  • Top Tier, A-Game Talent - How to Land em'

    - by GeekAgilistMercenary
    Recently the question came up from a close friend of mine, "will my PhD help me attain a higher income in the north west?"  I had to tell him, that it might get him a little more, but it won't get him in the top income brackets for the occupation.  Another time, a few days later, someone else asked this too.  Then again, I see a job posting that requires a Bachelors Degree and some other nonsense.  The job posting even states they want "A-Game" talent. I am almost shocked at how poorly part of this industry doesn't realize how unimportant a degree is to getting real top tier, a-game talent.  (and yes, I get a little riled up about this matter) You Can't Make Good Software Developers.  No college out there is going to train someone to be in the top 10%, and absolutely not to be in the top 5% of skill levels.  Colleges can NOT do this.  It is up to the individual, and the individual alone.  If top tier talent seems to come from a college, one should check their premise and look at the motivations the individuals have to go to that school.  There is most likely a reason that top tier talent appears to be made there.  The college however, can only guide or assist, but I repeat that "top tier talent is a very individualistic endeavor". Some might say, well a group is needed, support is needed, this and that are needed.  True, an individual needs a support system and a college can provide that, but it generally ends there.  The support group helps, provides a sounding wall, and provides correlation to good ideas for the a-game top tier geek.  But again, the endeavor is the individuals desire. top tier talent is a very individualistic endeavor - Me Hiring Top Tier, A-Game Talent There are a few things when trying to hire this level of game player. The first thing is to not require a degree of any sort.  Sure, it looks good, but it won't dictate anything other than the individual was able to go through the regimented steps of college. List the skills and ideas that you would like to find in an individual.  Think of two people meeting for the first time, what do you want to know about the other individual.  Team fit is absolutely fundamental for top tier talent.  That support group that I mentioned above, top tier talent works best with a solid group of players. Keep your technology up to date, moving forward, and don't bore your top talent if you manage to get it.  If the company slows down, they will leave.  The more valuable they find out they are, the lower tolerance they'll have for this.  For managers, directors, and leaders in an organization this is THE challenge for them. Provide opportunities not just for advancement, but ways for them to advance their knowledge such as training, a book budget, or other means.  Even if some software they want to use isn't used ton the project, get it for them (within reason of course ? couple $100 or even a few $1000 for a good software license to MSDN, Tellerik, or other suite of software is ideal). Don't push them to, and don't let them overwork themselves into burnout.  This, as a leader in an organization is easy to do if one finds themselves actually hiring top talent.  Because top talent just provides results and more results.  But they are human, they will break, don't be the cause of that or you'll lose your talent. For now, that is it from me on this topic, back to the revenue, code, projects, and pushing forward. For the original entry, check out my personal blog with other juicy tech tidbits, rants, raves, and the like. Agilist Mercenary

  • MAA a Database Machine-nel, maximális rendelkezésre állás

    - by Fekete Zoltán
    Néhány napja jelent meg egy, a maximális rendelkezésre állást boncolgató Oracle fehérpapír :): Oracle Data Guard: Disaster Recovery for Sun Oracle Database Machine. Ez a dokumentum az Exadata környezetben az Oracle Data Guard használatát elemzi. Az utolsó oldalakon néhány rendkívül hasznos linket is találunk. Mire is használható a Data Guard? - katasztrófa helyzet kezelése - adatbázis gördülo upgrade - egy megoldás az Exadata környezetre migrálásra - a standby adatbázis kihasználása A Sun Oracle Database Machine háromféle konfigurációban kapható: Full Rack, Half Rack és Quarter Rack, azaz teljes, fél és negyed szekrény kiépítésben. Felfelé upgrade-elheto és akár sok Full Rack összekapcsolva is egyetlen gépként tud muködni. A határ tehát a csillagos ég! :) Hiszen a nap a legfontosabb csillagunk. A Database Machine már önmagában is magas rendelkezésreállást biztosít, hiszen minden - a muködés szempontjából fontos - minden komponense legalább duplikált! Természetesen ez az adatokra is vonatkozik. A Database Machine ideális gyors környezet mind OLTP, mind DW futtatására, mind adatbázis konszolidációra. A tranzakciós (OLTP) rendszereknél régóta fontos követelmény, hogy az elsodleges site mögött legyen egy katasztrófa site, mely át tudja venni az adatbázis-kezelés feladatát, ha árvíz, tuz, vagy más szomorú katasztrófa történne az elsodleges site-on. Manapság már az adattárházak (DW) üzemeltetésében is fontos szerepet kap az MAA architektúra, azaz a Maximum Availability Architecture.

  • Oracle AutoVue Key Highlights from Oracle OpenWorld 2012

    - by Celine Beck
    We closed another successful Oracle Open World for AutoVue. Thanks to everyone who joined us this year. As usual, from customer presentations to evening networking activities, there was enough to keep us busy during the entire event. Here is a summary of some of the key highlights of the conference: Sessions:We had two AutoVue-specific sessions during Oracle Open World this year. The first session was part of the Product Lifecycle Management track and covered how AutoVue can be used to help drive effective decision making and streamline design for manufacturing processes. Attendees had the opportunity to learn from customer speaker GLOBALFOUNDRIES how they have been leveraging Oracle AutoVue within Agile PLM to enable high degree of collaboration during the exceptionally creative phases of their product development processes, securely, without risking valuable intellectual property. If you are interested, you can actually download the presentation by visiting launch.oracle.com/?plmopenworld2012.AutoVue was also featured as part of the Utilities track. This session focused on how visualization solutions play a critical role in effective plant optimization and configuration strategies defined by owners and operators of power generation facilities. Attendees learnt how integrated with document management systems, and enterprise applications like Oracle Primavera and Asset Lifecycle Management, AutoVue improves change management processes; minimizes risks by providing access to accurate engineering drawings which capture and reflect the as-maintained status of assets; and allows customers to drive complex maintenance projects to successful completion.Augmented Business Visualization for Agile PLMDuring Oracle Open World, we also showcased an Augmented Business Visualization-based solution for Oracle Agile PLM. An Augmented Business Visualization (ABV) solution is one where your structured data (from Oracle Agile PLM for instance) and your unstructured data (documents, designs, 3D models, etc) come together to allow you to make better decisions (check out our blog posts on the topic: Augment the Value of Your Data (or Time to replace the “attach” button) and Context is Everything ). As part of the Agile PLM, the idea is to support more effective decision-making by turning 3D assemblies into color-coded reports, and streamlining business processes like Engineering Change Management by enabling the automatic creation of engineering change requests in Agile PLM directly from documents being viewed in AutoVue. More on this coming soon...probably during the Oracle Value Chain Summit to be held in San Francisco, from Feb. 4-6, 2013 in San Francisco! Mark your calendars and stay tuned for more information! And thanks again for joining us at Oracle OpenWorld!

  • Release Management as Orchestra

    - by ericajanine
    I read an excellent, concise article (http://www.buildmeister.com/articles/software_release_management_best_practices) on the basics of release management practices. In the article, it states "Release Management is often likened to the conductor of an orchestra, with the individual changes to be implemented the various instruments within it." I played in music ensembles for years, so this is especially close to my heart as example. I learned most of my discipline from hours and hours of practice at the hand of a very skilled conductor and leader. I also learned that the true magic in symphonic performance is one where everyone involved is focused on one sound, one goal. In turn, that solid focus creates a sound and experience bigger than just mechanics alone accomplish. In symphony, a conductor's true purpose is to make you, a performer, better so the overall sound and end product is better. The big picture (the performance of the composition) is the end-game, and all musicians in the orchestra know without question their part makes up an important but incomplete piece of that performance. A good conductor works with each section (e.g. group) to ensure their individual pieces are solid. Let's restate: The conductor leads and is responsible for ensuring those pieces are solid. While the performers themselves are doing the work, the conductor is the final authority on when the pieces are ready or not. If not, the conductor initiates the efforts to get them ready or makes the decision to scrap their parts altogether for the sake of an overall performance. Let it sink in, because it's clear--It is not the performer's call if they play their part as agreed, it's the conductor's final call to allow it. In comparison, if a software release manager is a conductor, the only way for that manager to be effective is to drive the overarching process and execution of individual pieces of a software development lifecycle. It does not mean the release manager performs each and every piece, it means the release manager has oversight and influence because the end-game is a successful software enhancin a useable environment. It means the release manager, not the developer or development manager, has the final call if something goes into a software release. Of course, this is not a process of autocracy or dictation of absolute rule, it's cooperative effort. But the release manager must have the final authority to make a decision if something is ready to be added to the bigger piece, the overall symphony of software changes being considered for package and release. It also goes without saying a release manager, like a conductor, must have full autonomy and isolation from other software groups. A conductor is the one on the podium waving a little stick at the each section and cueing them for their parts, not yelling from the back of the room while also playing a tuba and taking direction from the horn section. I have personally seen where release managers are relegated to being considered little more than coordinators, red-tapers to "satisfy" the demands of an audit group without being bothered to actually respect all that a release manager gives a group willing to employ them fully. In this dysfunctional scenario, development managers, project managers, business users, and other stakeholders have been given nearly full clearance to demand and push their agendas forward, causing a tail-wagging-the-dog scenario where an inherent conflict will ensue. Depending on the strength, determination for peace, and willingness to overlook a built-in expectation that is wrong, the release manager here must face the crafted conflict head-on and diffuse it as quickly as possible. Then, the release manager must clearly make a case why a change cannot be released without negative impact to all parties involved. If a political agenda is solely driving a software release, there IS no symphony, there is no "software lifecycle". It's just out-of-tune noise. More importantly, there is no real conductor. Sometimes, just wanting to make a beautiful sound is not enough. If you are a release manager, are you freed up enough to move, to conduct the sections of software creation to ensure a solid release performance is possible? If not, it's time to take stock in what your role actually is and see if that is what you truly want to achieve in your position. If you are, then you can successfully build your career and that of the people in your groups to create truly beautiful software (music) together.

  • C++ Little Wonders: The C++11 auto keyword redux

    - by James Michael Hare
    I’ve decided to create a sub-series of my Little Wonders posts to focus on C++.  Just like their C# counterparts, these posts will focus on those features of the C++ language that can help improve code by making it easier to write and maintain.  The index of the C# Little Wonders can be found here. This has been a busy week with a rollout of some new website features here at my work, so I don’t have a big post for this week.  But I wanted to write something up, and since lately I’ve been renewing my C++ skills in a separate project, it seemed like a good opportunity to start a C++ Little Wonders series.  Most of my development work still tends to focus on C#, but it was great to get back into the saddle and renew my C++ knowledge.  Today I’m going to focus on a new feature in C++11 (formerly known as C++0x, which is a major move forward in the C++ language standard).  While this small keyword can seem so trivial, I feel it is a big step forward in improving readability in C++ programs. The auto keyword If you’ve worked on C++ for a long time, you probably have some passing familiarity with the old auto keyword as one of those rarely used C++ keywords that was almost never used because it was the default. That is, in the code below (before C++11): 1: int foo() 2: { 3: // automatic variables (allocated and deallocated on stack) 4: int x; 5: auto int y; 6:  7: // static variables (retain their value across calls) 8: static int z; 9:  10: return 0; 11: } The variable x is assumed to be auto because that is the default, thus it is unnecessary to specify it explicitly as in the declaration of y below that.  Basically, an auto variable is one that is allocated and de-allocated on the stack automatically.  Contrast this to static variables, that are allocated statically and exist across the lifetime of the program. Because auto was so rarely (if ever) used since it is the norm, they decided to remove it for this purpose and give it new meaning in C++11.  The new meaning of auto: implicit typing Now, if your compiler supports C++ 11 (or at least a good subset of C++11 or 0x) you can take advantage of type inference in C++.  For those of you from the C# world, this means that the auto keyword in C++ now behaves a lot like the var keyword in C#! For example, many of us have had to declare those massive type declarations for an iterator before.  Let’s say we have a std::map of std::string to int which will map names to ages: 1: std::map<std::string, int> myMap; And then let’s say we want to find the age of a given person: 1: // Egad that's a long type... 2: std::map<std::string, int>::const_iterator pos = myMap.find(targetName); Notice that big ugly type definition to declare variable pos?  Sure, we could shorten this by creating a typedef of our specific map type if we wanted, but now with the auto keyword there’s no need: 1: // much shorter! 2: auto pos = myMap.find(targetName); The auto now tells the compiler to determine what type pos should be based on what it’s being assigned to.  This is not dynamic typing, it still determines the type as if it were explicitly declared and once declared that type cannot be changed.  That is, this is invalid: 1: // x is type int 2: auto x = 42; 3:  4: // can't assign string to int 5: x = "Hello"; Once the compiler determines x is type int it is exactly as if we typed int x = 42; instead, so don’t' confuse it with dynamic typing, it’s still very type-safe. An interesting feature of the auto keyword is that you can modify the inferred type: 1: // declare method that returns int* 2: int* GetPointer(); 3:  4: // p1 is int*, auto inferred type is int 5: auto *p1 = GetPointer(); 6:  7: // ps is int*, auto inferred type is int* 8: auto p2 = GetPointer(); Notice in both of these cases, p1 and p2 are determined to be int* but in each case the inferred type was different.  because we declared p1 as auto *p1 and GetPointer() returns int*, it inferred the type int was needed to complete the declaration.  In the second case, however, we declared p2 as auto p2 which means the inferred type was int*.  Ultimately, this make p1 and p2 the same type, but which type is inferred makes a difference, if you are chaining multiple inferred declarations together.  In these cases, the inferred type of each must match the first: 1: // Type inferred is int 2: // p1 is int* 3: // p2 is int 4: // p3 is int& 5: auto *p1 = GetPointer(), p2 = 42, &p3 = p2; Note that this works because the inferred type was int, if the inferred type was int* instead: 1: // syntax error, p1 was inferred to be int* so p2 and p3 don't make sense 2: auto p1 = GetPointer(), p2 = 42, &p3 = p2; You could also use const or static to modify the inferred type: 1: // inferred type is an int, theAnswer is a const int 2: const auto theAnswer = 42; 3:  4: // inferred type is double, Pi is a static double 5: static auto Pi = 3.1415927; Thus in the examples above it inferred the types int and double respectively, which were then modified to const and static. Summary The auto keyword has gotten new life in C++11 to allow you to infer the type of a variable from it’s initialization.  This simple little keyword can be used to cut down large declarations for complex types into a much more readable form, where appropriate.   Technorati Tags: C++, C++11, Little Wonders, auto

  • Le Logiciel Libre – Omniprésent dans le secteur public

    - by gravax
    NOTE : Cet article a servi de base à du contenu publié en Juin 2011 dans le magazine Acteurs Publics. Créé il y a plusieurs décennies déjà, pour répondre à un besoin de partage de savoir, et de compétences, le Logiciel Libre existe sous plusieurs appellations, à l'origine anglo-saxonnes, dont « Free Software » et « Open Source » sont les plus utilisées. En Anglais, le mot « Free » pouvant signifier à la fois libre et gratuit, cela a créé une certaine confusion qui n'existe pas en Français avec le mot « libre ». Du coup, on voit souvent l’acronyme FOSS ou FLOSS, pour « Free, Libre, Open Source Software » afin d'éliminer l’ambiguïté. De nos jours, dans le secteur public, le logiciel libre est, depuis, devenu omniprésent. Il répond à plusieurs besoins critiques dont le contrôle des coûts, le choix (de partenaire, de logiciel, de fonctionnalités), la liberté de pouvoir modifier les applications pour les adapter à ses propres besoins, la sécurité provenant du fait que de nombreux développeurs et utilisateurs ont pu contrôler la qualité du code. Un autre aspect très présent dans les logiciels libres et l'adhérence quasi-systématique aux standards de l'industrie, qui garantit une intégration simple et facile au système d'information existant. Il y a cependant des éléments à prendre en compte lors des choix de logiciels libres stratégiques. Si l'aspect coûts est clairement un élément de choix qui peut conduire aux logiciels libres, il est principalement dû au fait qu'un logiciel libre existe souvent en version gratuite, librement téléchargeable. Mais ceci n'est que le le sommet de l'iceberg. Lors de la mise en production de logiciels il va falloir s'entourer de services dont l'intégration, où les possibilités de choix d'un partenaire seront d'autant plus grandes que le logiciel choisi est populaire et connu, ce qui conduira à des coups tirés vers le bas grâce à une concurrence saine. Mais il faudra aussi prévoir le support technique. La encore, la popularité du logiciel choisi augmentera la palette de prestataires de support possible. Le choix devra se faire suivant des critères très solides, et en particulier la capacité à s'engager sur des niveaux de service, la disponibilité 24 heures sur 24, 7 jours sur 7 (le pays ne s’arrête pas de fonctionner le week-end ou la nuit), et, éventuellement, la couverture géographique correspondant aux métiers que l'on exerce (un pays comme la France couvrant avec ses DOM et ses TOM une grande partie des fuseaux horaires et zones géographiques de la planète). La plus part des services publics, que ce soit éducation, santé, ou gouvernement, utilisent déjà des logiciels libres. On les retrouve coté infrastructure, avec des produits comme la base de données MySQL, fortement appréciée dans le monde de l'éducation pour construire des plate-formes d'e-éducation en conjonction avec d'autres produits libres tels Moodle, ou GlassFish, le serveur d'applications très prisé des développeurs pour son adhérence au standard Java EE version 6 et sa simplicité de mise-en-œuvre. Linux est extrêmement présent comme système d'exploitation libre dans le datacenter, mais aussi sur le poste de travail. On retrouve des outils de virtualisation tels Oracle VM, issu de Xen, dans le datacenter, et VirtualBox sur le poste du développeur. Avec une telle palette de solutions et d'outils dans le monde du Logiciel libre, Oracle se apporte au secteur public des réponses ciblées, efficaces, aux besoins du marché, y compris en matière de support technique et qualité de service associée.

  • Motores tecnológicos para el crecimiento económico

    - by Fabian Gradolph
    Oracle ha participado hoy en el IV Curso de Verano AMETIC-UPM. La presentación a corrido a cargo de José Manuel Peláez, director de Preventa de Tecnología de Oracle Ibérica, quien ha hecho una completa revisión de cuáles son los impulsores actuales de la innvovación y del desarrollo en el entorno de las tecnologías, haciendo honor al título del curso:  Las TIC en el nuevo entorno socio-económico: Motores de la recuperación económica y el empleo. Peláez, en su presentación "De la tecnología a la innovación: impulsores de la actividad económica",  ha comenzado destacando la importancia estratégica que hoy en día tienen las tecnologías para cualquier modelo de negocio. No se trata ya de hacer frente a la crisis económica, que también, sino sobre todo de hacer frente a los desafíos presentes y futuros de las empresas. En este sentido, es esencial hacer frente a un reto: el alto coste que tiene para las organizaciones la complejidad de sus sistemas tecnológicos. Hay un ejemplo que Oracle utiliza con frecuencia. Si un coche se comprase del mismo modo en que las empresas adquieren los sistemas de información, compraríamos por un lado la carrocería, por otro lado el motor, las ventanas, el cambio de marchas, etc... y luego pasaríamos un tiempo muy interesante montándolo todo en casa. La pregunta clave es: ¿por qué no adquirir los sistemas de información ya preparados para funcionar, al igual que compramos un coche?. El sector TI, con Oracle a la cabeza, está dando uina respuesta adecuada con los sistemas de ingenería conjunta. Se trata de sistemas de hardware y software diseñados y concebidos de forma integrada que reducen considerablemente el tiempo necesario para la implementación, los costes de integración y los costes de energía y mantenimiento. La clave de esta forma de adquirir la tecnología, según ha explicado Peláez, es que al reducir la complejidad y los costes asociados, se están liberando recursos que pueden dedicarse a otras necesidades. Según los datos de Gartner, de la cantidad de recursos invertidos por las empresas en TI, el 63% se dedica a tareas de puro funcionamiento, es decir, a mantener el negocio en marcha. La parte de presupuesto que se dedica a crecimiento del negocio es el 21%, mientras que sólo un 16% se dedica a transformación, es decir, a innovación. Sólo mediante la utilización de tecnologías más eficientes -como los sistemas de ingeniería conjunta-, que lleven aparejados menores costes, es viable reducir ese 63% y dedicar más recursos al crecimiento y la innovación. Ahora bien, una vez liberados los recursos económicos, ¿hacia dónde habría que dirigir las inversiones en tecnología?. José Manuel Peláez ha destacado algunas áreas esenciales como son Big Data, Cloud Computing, los retos de la movilidad y la necesidad de mejorar la experiencia de los clientes, entre otros. Cada uno de estos aspectos lleva aparejados nuevos retos empresariales, pero sólo las empresas que sean capaces de integrarlos en su ADN e incorporarlos al corazón de su estrategia de negocio, podrán diferenciarse en el panorama competitivo del siglo XXI. Desde estas páginas los iremos desgranando poco a poco.

  • New Whitepaper: Planning Your E-Business Suite Upgrade from Release 11i to 12.1

    [Editor:  This guest article has been contributed by Anne Carlson]Premier Support for Oracle E-Business Suite Release 11i ends in November 2010.  At Oracle OpenWorld last fall, it was standing room only at several EBS upgrade sessions.  Responding to the increased interest in upgrades, I set to work on a new Release 12.1 version of our popular whitepaper, Best Practices for Adopting E-Business Suite, Release 12 (Note 580299.1). Here is that new whitepaper, which features the latest Release 12.1 upgrade planning advice from Oracle's Support, Consulting, Development and IT organizations:Planning Your E-Business Suite Upgrade from 11i to Release 12.1 (Note 987516.1)The paper is directed at IT professionals who are planning, managing, or running a Release 12.1 upgrade project.  After briefly reviewing the Release 12.1 value proposition, the paper launches into specific upgrade planning tips to help you:

  • Oracle is a Leader again in Gartner’s Magic Quadrant for E-commerce

    - by David Dorf
    Although e-commerce represents only 10% of the typical brick-and-mortar retailer’s sales, that percentage continues to climb.  So it’s no wonder that many retailers are considering the purchase of new e-commerce platforms to provide a commerce experience that keeps customers coming back.  And once again, Oracle and IBM lead the pack, identified as leaders in Gartner’s 2013 Magic Quadrant for E-Commerce along with hybris.  Many retailers are realizing the need to support Commerce Anywhere, allowing customers to interact with brands on their own terms.  Gartner reinforces this trend saying, “E-commerce is moving beyond just an online selling channel to integrated platforms delivering a unified customer experience. Traditionally, most organizations have been investing in the online channels with the objective of driving additional sales. However, customers increasingly are expecting a seamless buying experience across all channels, and e-commerce is a critical part of this evolution since it is a point where other channels are integrating to synchronize the customer experience across channels." Oracle saw this trend coming and acquired ATG, FatWire, and Endeca, all leaders in their respective markets, starting back in 2010.  The assets have been combined as Oracle Commerce and represent a comprehensive solution for retailers to sell via the Web while offering the best customer experience possible.  Retailers like JCPenney, American Apparel, and Kohl’s have recently licensed Oracle Commerce as part of their transformations. In the next two years we’ll begin to see more separation between the retailers that have a Commerce Anywhere strategy, and those that continue to flail with separate channels.  Integrating online and offline commerce, along with mobile and social aspects are becoming crucial to success in the industry.

  • Would You Like It In Green?

    - by steve.diamond
    OK, so admittedly, this is already a TIRED and HACKNEYED term, but it applies here, so please endure the following. If you would like it in green, then yes, "We have an app for that!" In the soon-to-be-introduced next release of Oracle CRM On Demand, organizations gain unprecedented flexibility in their ability to optimize the look and feel of the Oracle CRM On Demand user interface. So if you want it in green, you can have it in green. And on this topic, I must say...our product development team seems to be taking unabashed pleasure in displaying this new color flexibility. Their demos are increasingly displaying a color palette that would make Martha Stewart hurl. And when I offer any feedback in my typically "direct" manner, they respond with, "Well Diamond, we can't show red or blue now, can we? It would just look like...everything else!" Yeah....but....but...I'm wearing a white shirt today, just like the white shirt I wore yesterday. And my wife has a fondness for "Shabby Chic," which is an interior design style deploying mostly white backdrops. Therefore, I guess I'm not the best one to critique. In all seriousness, although we'll be profiling far meatier features in the next release of Oracle CRM On Demand, this is important for organizations that want to match the look and feel of their CRM application to their corporate branding standards. Oh, and Happy St. Patrick's Day.

  • ?Portal Content Personalization

    - by john.brunswick
    To make the most effective use of a portal and content management platform, personalization is a critical component of delivering the most value to end users. Regardless of what type of constituents you may be serving, content relevance is critical to support business goals like self-service, communication within a geographically distributed organization, lead generation and customer loyalty effectively. This especially holds true when serving external parties, as they generally have a lower threshold for digging through your site to locate a particular item of interest and are apt to leave or dial a helpdesk if their efforts cannot locate the relevant information. Optimal delivery of content can be achieved through a variety of methods, but it is generally a blend of security and filtering via meta data that can drive the most return with the least amount of upfront effort and ongoing upkeep. In a portal environment various platform components have their strong suits and by combining the capabilities of enterprise portal and content platforms much of the groundwork for personalization can be achieved in a configuration-based manner. In our discussion we will cover terminology and concepts, example scenarios and technical implementation strategies to help showcase how personalization of content can be achieved within a portal from a technical and strategic standpoint. Read on to better understand the chart below and the components at our disposal to personalize content delivery. Read on... click here to view a full size chart

  • How-to tell the ViewCriteria a user chose in an af:query component

A View Criteria is a named where clauses that you can create declaratively on the ADF Business Component View Object. A default View Criteria that allows users to search in all attributes exists by default and exposed in the Data Controls panel. To create an ADF Faces search form, expand the View Object node that contains the View Criteria definition in the Data Controls panel. Drag the View Criteria that should be displayed as the default criteria onto the page and choose Query in the opened context menu. One of the options within the Query option is to create an ADF Query Panel with Table, which displays the result set in a table view, which can have additional column filters defined. Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} To intercept the user query for modification, or just to know about the selected View Criteria, you override the QueryListener property on the af:query component of the af:table component. Overriding the QueryListener on the table makes sense if the table allows users to further filter the result set using column filters.To override the default QueryListener, copy the existing string referencing the binding layer to the clipboard and then select Edit from the field context menu (press the arrow icon to open it) to selecte or create a new managed bean and method to handle the query event.  The code below is from a managed bean with custom query listener handlers defined for the af:query component and the af:table component. The default listener entry copied to the clipboard was "#{bindings.ImplicitViewCriteriaQuery.processQuery}"  public void onQueryList(QueryEvent queryEvent) {   // The generated QueryListener replaced by this method   //#{bindings.ImplicitViewCriteriaQuery.processQuery}        QueryDescriptor qdes = queryEvent.getDescriptor();          //print or log selected View Criteria   System.out.println("NAME "+qdes.getName());           //call default Query Event        invokeQueryEventMethodExpression("      #{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);  } public void onQueryTable(QueryEvent queryEvent) {   // The generated QueryListener replaced by this method   //#{bindings.ImplicitViewCriteriaQuery.processQuery}   QueryDescriptor qdes = queryEvent.getDescriptor();   //print or log selected View Criteria   System.out.println("NAME "+qdes.getName());                   invokeQueryEventMethodExpression(     "#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent); } private void invokeQueryEventMethodExpression(                        String expression, QueryEvent queryEvent){   FacesContext fctx = FacesContext.getCurrentInstance();   ELContext elctx = fctx.getELContext();   ExpressionFactory efactory   fctx.getApplication().getExpressionFactory();     MethodExpression me =     efactory.createMethodExpression(elctx,expression,                                     Object.class,                                     new Class[]{QueryEvent.class});     me.invoke(elctx, new Object[]{queryEvent}); } Of course, this code also can be used as a starting point for other query manipulations and also works with saved custom criterias.

  • Flow-Design Cheat Sheet &ndash; Part I, Notation

    - by Ralf Westphal
    You want to avoid the pitfalls of object oriented design? Then this is the right place to start. Use Flow-Oriented Analysis (FOA) and –Design (FOD or just FD for Flow-Design) to understand a problem domain and design a software solution. Flow-Orientation as described here is related to Flow-Based Programming, Event-Based Programming, Business Process Modelling, and even Event-Driven Architectures. But even though “thinking in flows” is not new, I found it helpful to deviate from those precursors for several reasons. Some aim at too big systems for the average programmer, some are concerned with only asynchronous processing, some are even not very much concerned with programming at all. What I was looking for was a design method to help in software projects of any size, be they large or tiny, involing synchronous or asynchronous processing, being local or distributed, running on the web or on the desktop or on a smartphone. That´s why I took ideas from all of the above sources and some additional and came up with Event-Based Components which later got repositioned and renamed to Flow-Design. In the meantime this has generated some discussion (in the German developer community) and several teams have started to work with Flow-Design. Also I´ve conducted quite some trainings using Flow-Orientation for design. The results are very promising. Developers find it much easier to design software using Flow-Orientation than OOAD-based object orientation. Since Flow-Orientation is moving fast and is not covered completely by a single source like a book, demand has increased for at least an overview of the current state of its notation. This page is trying to answer this demand by briefly introducing/describing every notational element as well as their translation into C# source code. Take this as a cheat sheet to put next to your whiteboard when designing software. However, please do not expect any explanation as to the reasons behind Flow-Design elements. Details on why Flow-Design at all and why in this specific way you´ll find in the literature covering the topic. Here´s a resource page on Flow-Design/Event-Based Components, if you´re able to read German. Notation Connected Functional Units The basic element of any FOD are functional units (FU): Think of FUs as some kind of software code block processing data. For the moment forget about classes, methods, “components”, assemblies or whatever. See a FU as an abstract piece of code. Software then consists of just collaborating FUs. I´m using circles/ellipses to draw FUs. But if you like, use rectangles. Whatever suites your whiteboard needs best.   The purpose of FUs is to process input and produce output. FUs are transformational. However, FUs are not called and do not call other FUs. There is no dependency between FUs. Data just flows into a FU (input) and out of it (output). From where and where to is of no concern to a FU.   This way FUs can be concatenated in arbitrary ways:   Each FU can accept input from many sources and produce output for many sinks:   Flows Connected FUs form a flow with a start and an end. Data is entering a flow at a source, and it´s leaving it through a sink. Think of sources and sinks as special FUs which conntect wires to the environment of a network of FUs.   Wiring Details Data is flowing into/out of FUs through wires. This is to allude to electrical engineering which since long has been working with composable parts. Wires are attached to FUs usings pins. They are the entry/exit points for the data flowing along the wires. Input-/output pins currently need not be drawn explicitly. This is to keep designing on a whiteboard simple and quick.   Data flowing is of some type, so wires have a type attached to them. And pins have names. If there is only one input pin and output pin on a FU, though, you don´t need to mention them. The default is Process for a single input pin, and Result for a single output pin. But you´re free to give even single pins different names.   There is a shortcut in use to address a certain pin on a destination FU:   The type of the wire is put in parantheses for two reasons. 1. This way a “no-type” wire can be easily denoted, 2. this is a natural way to describe tuples of data.   To describe how much data is flowing, a star can be put next to the wire type:   Nesting – Boards and Parts If more than 5 to 10 FUs need to be put in a flow a FD starts to become hard to understand. To keep diagrams clutter free they can be nested. You can turn any FU into a flow: This leads to Flow-Designs with different levels of abstraction. A in the above illustration is a high level functional unit, A.1 and A.2 are lower level functional units. One of the purposes of Flow-Design is to be able to describe systems on different levels of abstraction and thus make it easier to understand them. Humans use abstraction/decomposition to get a grip on complexity. Flow-Design strives to support this and make levels of abstraction first class citizens for programming. You can read the above illustration like this: Functional units A.1 and A.2 detail what A is supposed to do. The whole of A´s responsibility is decomposed into smaller responsibilities A.1 and A.2. FU A thus does not do anything itself anymore! All A is responsible for is actually accomplished by the collaboration between A.1 and A.2. Since A now is not doing anything anymore except containing A.1 and A.2 functional units are devided into two categories: boards and parts. Boards are just containing other functional units; their sole responsibility is to wire them up. A is a board. Boards thus depend on the functional units nested within them. This dependency is not of a functional nature, though. Boards are not dependent on services provided by nested functional units. They are just concerned with their interface to be able to plug them together. Parts are the workhorses of flows. They contain the real domain logic. They actually transform input into output. However, they do not depend on other functional units. Please note the usage of source and sink in boards. They correspond to input-pins and output-pins of the board.   Implicit Dependencies Nesting functional units leads to a dependency tree. Boards depend on nested functional units, they are the inner nodes of the tree. Parts are independent, they are the leafs: Even though dependencies are the bane of software development, Flow-Design does not usually draw these dependencies. They are implicitly created by visually nesting functional units. And they are harmless. Boards are so simple in their functionality, they are little affected by changes in functional units they are depending on. But functional units are implicitly dependent on more than nested functional units. They are also dependent on the data types of the wires attached to them: This is also natural and thus does not need to be made explicit. And it pertains mainly to parts being dependent. Since boards don´t do anything with regard to a problem domain, they don´t care much about data types. Their infrastructural purpose just needs types of input/output-pins to match.   Explicit Dependencies You could say, Flow-Orientation is about tackling complexity at its root cause: that´s dependencies. “Natural” dependencies are depicted naturally, i.e. implicitly. And whereever possible dependencies are not even created. Functional units don´t know their collaborators within a flow. This is core to Flow-Orientation. That makes for high composability of functional units. A part is as independent of other functional units as a motor is from the rest of the car. And a board is as dependend on nested functional units as a motor is on a spark plug or a crank shaft. With Flow-Design software development moves closer to how hardware is constructed. Implicit dependencies are not enough, though. Sometimes explicit dependencies make designs easier – as counterintuitive this might sound. So FD notation needs a ways to denote explicit dependencies: Data flows along wires. But data does not flow along dependency relations. Instead dependency relations represent service calls. Functional unit C is depending on/calling services on functional unit S. If you want to be more specific, name the services next to the dependency relation: Although you should try to stay clear of explicit dependencies, they are fundamentally ok. See them as a way to add another dimension to a flow. Usually the functionality of the independent FU (“Customer repository” above) is orthogonal to the domain of the flow it is referenced by. If you like emphasize this by using different shapes for dependent and independent FUs like above. Such dependencies can be used to link in resources like databases or shared in-memory state. FUs can not only produce output but also can have side effects. A common pattern for using such explizit dependencies is to hook a GUI into a flow as the source and/or the sink of data: Which can be shortened to: Treat FUs others depend on as boards (with a special non-FD API the dependent part is connected to), but do not embed them in a flow in the diagram they are depended upon.   Attributes of Functional Units Creation and usage of functional units can be modified with attributes. So far the following have shown to be helpful: Singleton: FUs are by default multitons. FUs in the same of different flows with the same name refer to the same functionality, but to different instances. Think of functional units as objects that get instanciated anew whereever they appear in a design. Sometimes though it´s helpful to reuse the same instance of a functional unit; this is always due to valuable state it holds. Signify this by annotating the FU with a “(S)”. Multiton: FUs on which others depend are singletons by default. This is, because they usually are introduced where shared state comes into play. If you want to change them to be a singletons mark them with a “(M)”. Configurable: Some parts need to be configured before the can do they work in a flow. Annotate them with a “(C)” to have them initialized before any data items to be processed by them arrive. Do not assume any order in which FUs are configured. How such configuration is happening is an implementation detail. Entry point: In each design there needs to be a single part where “it all starts”. That´s the entry point for all processing. It´s like Program.Main() in C# programs. Mark the entry point part with an “(E)”. Quite often this will be the GUI part. How the entry point is started is an implementation detail. Just consider it the first FU to start do its job.   Patterns / Standard Parts If more than a single wire is attached to an output-pin that´s called a split (or fork). The same data is flowing on all of the wires. Remember: Flow-Designs are synchronous by default. So a split does not mean data is processed in parallel afterwards. Processing still happens synchronously and thus one branch after another. Do not assume any specific order of the processing on the different branches after the split.   It is common to do a split and let only parts of the original data flow on through the branches. This effectively means a map is needed after a split. This map can be implicit or explicit.   Although FUs can have multiple input-pins it is preferrable in most cases to combine input data from different branches using an explicit join: The default output of a join is a tuple of its input values. The default behavior of a join is to output a value whenever a new input is received. However, to produce its first output a join needs an input for all its input-pins. Other join behaviors can be: reset all inputs after an output only produce output if data arrives on certain input-pins

  • The APEX of Business Value...or...the Business Value of APEX? Oracle Cloud Takes Oracle APEX to New Heights!

    - by Gene Eun
    The attraction of Oracle Application Express (APEX) has increased tremendously with the recent launch of the Oracle Cloud. APEX already supported departmental development and deployment of business applications with minimal involvement from the IT department. Positioned as the ideal replacement for MS Access, APEX probably has managed better to capture the eye of developers and was used for enterprise application development at least as much as for the kind of tactical applications that Oracle strategically positioned it for. With APEX as PaaS from the Oracle Cloud, a leap is made to a much higher level of business value. Now the IT department is not even needed to make infrastructure available with a database running  on it. All the business needs is a credit card. And the business application that is developed, managed and used from the cloud through a standard browser can now just as easily be accessed by users from around the world as by users from the business department itself. As a bonus – the development of the APEX application is also done in the cloud – with no special demands on the location or the enterprise access privileges of the developers. To sum it up: APEX from Oracle Cloud Database Service get the development environment up and running in minutes no involvement from the internal IT department required (not for infrastructure, platform, or development) superior availability and scalability is offered by Oracle users from anywhere in the world can be invited to access the application developers from anywhere in the world can participate in creating and maintaining the application In addition: because the Oracle Cloud platform is the same as the on-premise platform, you can still decide to move the APEX application between the cloud and the local environment – and back again. The REST-ful services that are available through APEX allow programmatic interaction with the database under the APEX application. That means that this database can be synchronized with on premise databases or data stores in (other) clouds. Through the Oracle Cloud Messaging Service, the APEX application can easily enter into asynchronous conversations with other APEX applications, Fusion Middleware applications (ADF, SOA, BPM) and any other type of REST-enabled application. In my opinion, now, for the first time perhaps, APEX offers the attraction to the business that has been suggested before: because of the cloud, all the business needs is  a credit card (a budget of $175 per month), an internet-connection and a browser. Not like before, with a PC hidden under a desk or a database running somewhere in the data center. No matter how unattended: equipment is needed, power is consumed, the database needs to be kept running and if Oracle Database XE does not suffice, software licenses are required as well. And this set up always has a security challenge associated with it. The cloud fee for the Oracle Cloud Database Service includes infrastructure, power, licenses, availability, platform upgrades, a collection of reusable application components and the development and runtime environments containing the APEX platform. Of course this not only means that business departments can move quickly without having to convince their IT colleagues to move along – it also means that small organizations that do not even have IT colleagues can do the same. Getting tailored applications or applications up and running to get in touch with users and customers all over the world is now within easy reach for small outfits – without any investment. My misunderstanding For a long time, I was under the impression that the essence of APEX was that the business could create applications themselves – meaning that business ‘people’ would actually go into APEX to create the application. To me APEX was too much of a developers’ tool to see that happen – apart from the odd business analyst who missed his or her calling as an IT developer. Having looked at various other cloud based development offerings – including Force.com, Mendix, WaveMaker, WorkXpress, OrangeScape, Caspio and Cordys- I have come to realize my mistake. All these platforms are positioned for 'the business' but require a fair amount of coding and technical expertise. However, they make the business happy nevertheless, because they allow the  business to completely circumvent the IT department. That is the essence. Not having to go through the red tape, not having to wait for IT staff who (justifiably) need weeks or months to provide an environment, not having to deal with administrators (again, justifiably) refusing to take on that 'strange environment'. Being able to think of an initiative and turn into action right away. The business does not have to build the application - it can easily hire some external developers or even that nerdy boy next door. They can get started, get an application up and running and invite users in – especially external users such as customers. They will worry later about upgrades and life cycle management and integration. To get applications up and running quickly and start turning ideas into action and results rightaway. That is the key selling point for all these cloud offerings, including APEX from the Cloud. And it is a compelling story. For APEX probably even more so than for the others. While I consider APEX a somewhat proprietary framework compared with ‘regular’ Java/JEE web development (or even .NET and PHP  development), it is still far more open than most cloud environments. APEX is SQL and PL/SQL based – nothing special about those languages – and can run just as easily on site as in the cloud. It has been around since 2004 (that is not including several predecessors that fed straight into APEX) so it can be considered pretty mature. Oracle as a company seems pretty stable – so investments in its technology are bound to last for some time to come. By the way: neither APEX nor the other Cloud DevaaS offerings are targeted at creating applications with enormous life times. They fit into a trend of agile development and rapid life cycle management, with fairly light weight user interfaces that quickly adapt to taste, technology trends and functional requirements and that are easily replaced. APEX and ADF – a match made in heaven?! (or at least in the sky) Note that using APEX only for cloud based database with REST-ful Services is also a perfectly viable scenario: any UI – mobile or browser based – capable of consuming REST-ful services can be created against such a business tier. Creating an ADF Mobile application for example that runs aginst REST-ful services is a best practice for mobile development. Such REST-ful services can be consumed from any service provider – including the Cloud based APEX powered REST-ful services running against the Oracle Cloud Database Service! The ADF Mobile architecture overview can easily be morphed to fit the APEX services in – allowing for a cloud based mobile app: Want to learn more about Oracle Database Cloud Service or Oracle Cloud, just visit cloud.oracle.com  or oracle.com/cloud.

  • Caching NHibernate Named Queries

    - by TStewartDev
    I recently started a new job and one of my first tasks was to implement a "popular products" design. The parameters were that it be done with NHibernate and be cached for 24 hours at a time because the query will be pretty taxing and the results do not need to be constantly up to date. This ended up being tougher than it sounds. The database schema meant a minimum of four joins with filtering and ordering criteria. I decided to use a stored procedure rather than letting NHibernate create the SQL for me. Here is a summary of what I learned (even if I didn't ultimately use all of it): You can't, at the time of this writing, use Fluent NHibernate to configure SQL named queries or imports You can return persistent entities from a stored procedure and there are a couple ways to do that You can populate POCOs using the results of a stored procedure, but it isn't quite as obvious You can reuse your named query result mapping other places (avoid duplication) Caching your query results is not at all obvious Testing to see if your cache is working is a pain NHibernate does a lot of things right. Having unified, up-to-date, comprehensive, and easy-to-find documentation is not one of them. By the way, if you're new to this, I'll use the terms "named query" and "stored procedure" (from NHibernate's perspective) fairly interchangeably. Technically, a named query can execute any SQL, not just a stored procedure, and a stored procedure doesn't have to be executed from a named query, but for reusability, it seems to me like the best practice. If you're here, chances are good you're looking for answers to a similar problem. You don't want to read about the path, you just want the result. So, here's how to get this thing going. The Stored Procedure NHibernate has some guidelines when using stored procedures. For Microsoft SQL Server, you have to return a result set. The scalar value that the stored procedure returns is ignored as are any result sets after the first. Other than that, it's nothing special. CREATE PROCEDURE GetPopularProducts @StartDate DATETIME, @MaxResults INT AS BEGIN SELECT [ProductId], [ProductName], [ImageUrl] FROM SomeTableWithJoinsEtc END The Result Class - PopularProduct You have two options to transport your query results to your view (or wherever is the final destination): you can populate an existing mapped entity class in your model, or you can create a new entity class. If you go with the existing model, the advantage is that the query will act as a loader and you'll get full proxied access to the domain model. However, this can be a disadvantage if you require access to the related entities that aren't loaded by your results. For example, my PopularProduct has image references. Unless I tie them into the query (thus making it even more complicated and expensive to run), they'll have to be loaded on access, requiring more trips to the database. Since we're trying to avoid trips to the database by using a second-level cache, we should use the second option, which is to create a separate entity for results. This approach is (I believe) in the spirit of the Command-Query Separation principle, and it allows us to flatten our data and optimize our report-generation process from data source to view. public class PopularProduct { public virtual int ProductId { get; set; } public virtual string ProductName { get; set; } public virtual string ImageUrl { get; set; } } The NHibernate Mappings (hbm) Next up, we need to let NHibernate know about the query and where the results will go. Below is the markup for the PopularProduct class. Notice that I'm using the <resultset> element and that it has a name attribute. The name allows us to drop this into our query map and any others, giving us reusability. Also notice the <import> element which lets NHibernate know about our entity class. <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <import class="PopularProduct, Infrastructure.NHibernate, Version=1.0.0.0"/> <resultset name="PopularProductResultSet"> <return-scalar column="ProductId" type="System.Int32"/> <return-scalar column="ProductName" type="System.String"/> <return-scalar column="ImageUrl" type="System.String"/> </resultset> </hibernate-mapping>  And now the PopularProductsMap: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="GetPopularProducts" resultset-ref="PopularProductResultSet" cacheable="true" cache-mode="normal"> <query-param name="StartDate" type="System.DateTime" /> <query-param name="MaxResults" type="System.Int32" /> exec GetPopularProducts @StartDate = :StartDate, @MaxResults = :MaxResults </sql-query> </hibernate-mapping>  The two most important things to notice here are the resultset-ref attribute, which links in our resultset mapping, and the cacheable attribute. The Query Class – PopularProductsQuery So far, this has been fairly obvious if you're familiar with NHibernate. This next part, maybe not so much. You can implement your query however you want to; for me, I wanted a self-encapsulated Query class, so here's what it looks like: public class PopularProductsQuery : IPopularProductsQuery { private static readonly IResultTransformer ResultTransformer; private readonly ISessionBuilder _sessionBuilder;   static PopularProductsQuery() { ResultTransformer = Transformers.AliasToBean<PopularProduct>(); }   public PopularProductsQuery(ISessionBuilder sessionBuilder) { _sessionBuilder = sessionBuilder; }   public IList<PopularProduct> GetPopularProducts(DateTime startDate, int maxResults) { var session = _sessionBuilder.GetSession(); var popularProducts = session .GetNamedQuery("GetPopularProducts") .SetCacheable(true) .SetCacheRegion("PopularProductsCacheRegion") .SetCacheMode(CacheMode.Normal) .SetReadOnly(true) .SetResultTransformer(ResultTransformer) .SetParameter("StartDate", startDate.Date) .SetParameter("MaxResults", maxResults) .List<PopularProduct>();   return popularProducts; } }  Okay, so let's look at each line of the query execution. The first, GetNamedQuery, matches up with our NHibernate mapping for the sql-query. Next, we set it as cacheable (this is probably redundant since our mapping also specified it, but it can't hurt, right?). Then we set the cache region which we'll get to in the next section. Set the cache mode (optional, I believe), and my cache is read-only, so I set that as well. The result transformer is very important. This tells NHibernate how to transform your query results into a non-persistent entity. You can see I've defined ResultTransformer in the static constructor using the AliasToBean transformer. The name is obviously leftover from Java/Hibernate. Finally, set your parameters and then call a result method which will execute the query. Because this is set to cached, you execute this statement every time you run the query and NHibernate will know based on your parameters whether to use its cached version or a fresh version. The Configuration – hibernate.cfg.xml and Web.config You need to explicitly enable second-level caching in your hibernate configuration: <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> [...] <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider,NHibernate.Caches.SysCache</property> <property name="cache.use_query_cache">true</property> <property name="cache.use_second_level_cache">true</property> [...] </session-factory> </hibernate-configuration> Both properties "use_query_cache" and "use_second_level_cache" are necessary. As this is for a web deployement, we're using SysCache which relies on ASP.NET's caching. Be aware of this if you're not deploying to the web! You'll have to use a different cache provider. We also need to tell our cache provider (in this cache, SysCache) about our caching region: <syscache> <cache region="PopularProductsCacheRegion" expiration="86400" priority="5" /> </syscache> Here I've set the cache to be valid for 24 hours. This XML snippet goes in your Web.config (or in a separate file referenced by Web.config, which helps keep things tidy). The Payoff That should be it! At this point, your queries should run once against the database for a given set of parameters and then use the cache thereafter until it expires. You can, of course, adjust settings to work in your particular environment. Testing Testing your application to ensure it is using the cache is a pain, but if you're like me, you want to know that it's actually working. It's a bit involved, though, so I'll create a separate post for it if comments indicate there is interest.

  • My New BDD Style

    - by Liam McLennan
    I have made a change to my code-based BDD style. I start with a scenario such as: Pre-Editing * Given I am a book editor * And some chapters are locked and some are not * When I view the list of chapters for editing * Then I should see some chapters are editable and are not locked * And I should see some chapters are not editable and are locked and I implement it using a modified SpecUnit base class as: [Concern("Chapter Editing")] public class when_pre_editing_a_chapter : BaseSpec { private User i; // other context variables protected override void Given() { i_am_a_book_editor(); some_chapters_are_locked_and_some_are_not(); } protected override void Do() { i_view_the_list_of_chapters_for_editing(); } private void i_am_a_book_editor() { i = new UserBuilder().WithUsername("me").WithRole(UserRole.BookEditor).Build(); } private void some_chapters_are_locked_and_some_are_not() { } private void i_view_the_list_of_chapters_for_editing() { } [Observation] public void should_see_some_chapters_are_editable_and_are_not_locked() { } [Observation] public void should_see_some_chapters_are_not_editable_and_are_locked() { } } and the output from the specunit report tool is: Chapter Editing specifications    1 context, 2 specifications Chapter Editing, when pre editing a chapter    2 specifications should see some chapters are editable and are not locked should see some chapters are not editable and are locked The intent is to provide a clear mapping from story –> scenarios –> bdd tests.
