  • Defining Discovery: Core Concepts

    - by Joe Lamantia
    Discovery tools have had a referencable working definition since at least 2001, when Ben Shneiderman published 'Inventing Discovery Tools: Combining Information Visualization with Data Mining'.  Dr. Shneiderman suggested the combination of the two distinct fields of data mining and information visualization could manifest as new category of tools for discovery, an understanding that remains essentially unaltered over ten years later.  An industry analyst report titled Visual Discovery Tools: Market Segmentation and Product Positioning from March of this year, for example, reads, "Visual discovery tools are designed for visual data exploration, analysis and lightweight data mining." Tools should follow from the activities people undertake (a foundational tenet of activity centered design), however, and Dr. Shneiderman does not in fact describe or define discovery activity or capability. As I read it, discovery is assumed to be the implied sum of the separate fields of visualization and data mining as they were then understood.  As a working definition that catalyzes a field of product prototyping, it's adequate in the short term.  In the long term, it makes the boundaries of discovery both derived and temporary, and leaves a substantial gap in the landscape of core concepts around discovery, making consensus on the nature of most aspects of discovery difficult or impossible to reach.  I think this definitional gap is a major reason that discovery is still an ambiguous product landscape. To help close that gap, I'm suggesting a few definitions of four core aspects of discovery.  These come out of our sustained research into discovery needs and practices, and have the goal of clarifying the relationship between discvoery and other analytical categories.  They are suggested, but should be internally coherent and consistent.   Discovery activity is: "Purposeful sense making activity that intends to arrive at new insights and understanding through exploration and analysis (and for these we have specific defintions as well) of all types and sources of data." Discovery capability is: "The ability of people and organizations to purposefully realize valuable insights that address the full spectrum of business questions and problems by engaging effectively with all types and sources of data." Discovery tools: "Enhance individual and organizational ability to realize novel insights by augmenting and accelerating human sense making to allow engagement with all types of data at all useful scales." Discovery environments: "Enable organizations to undertake effective discovery efforts for all business purposes and perspectives, in an empirical and cooperative fashion." Note: applicability to a world of Big data is assumed - thus the refs to all scales / types / sources - rather than stated explicitly.  I like that Big Data doesn't have to be written into this core set of definitions, b/c I think it's a transitional label - the new version of Web 2.0 - and goes away over time.

  • How Microsoft listens

    - by Stacy Vicknair
    This being my freshman year as an MVP, I had a realization that I perhaps should be embarrassed hasn’t happened sooner. The realization comes much like the iconic M&Ms commercial where the M&Ms run into Santa and exclaim, “He does exist!” My personal realization arguably has a greater implication: Microsoft does listen. This is the most important lesson that I received this year attending the MVP Summit. My hope is that I can convince you that we are empowered to make a difference. Instead of using “Man I hate how this works / doesn’t work!” as cooler conversation, we can use it as true interaction with Microsoft. We as customers to Microsoft need to stop asking the question “Will this work for me?” and instead ask “How can this work for me?” There are three quick resources that the average developer has access to today that they can use to be heard by the product teams, and by no means should you think twice if you have a concern that you’d like a real response on. MVPs MVPs are members of your community who have a deep relationship with Microsoft and will have connections to their associated product group. Don’t think of them as just a resource for answers, but also as your ambassador for getting your experiences heard. You can find your local MVPs by browsing the directory at: https://mvp.support.microsoft.com/communities/mvp.aspx Evangelists Evangelists are employees of Microsoft who work to foster and grow communities in their assigned region. They are first-class citizens of Microsoft and are often deeply involved with the product groups. As a result, they will be more than glad to direct your questions or concerns to those who can answer them most expertly. With that said, evangelists are also very busy people (who do amazing things for the community) and might not be able to get you that conversation as quickly as a local MVP. You can find your local evangelist at the following website: http://msdn.microsoft.com/en-us/bb905078.aspx Microsoft Connect This is one of the resources that I haven’t used enough, but it cannot be understated. Connect is the starting point of the social conversation that happens between Microsoft and the community daily. Connect acts as a portal where you can provide new feedback as well as comment and rate the feedback provided by others. Power is in numbers when it comes to Connect, so the exposure that your feedback can get not only lets you know that you aren’t the only one who wants change, but also lets Microsoft know the same. https://connect.microsoft.com   Technorati Tags: Microsoft,MVP,Feedback,Connect

  • Walking to the North Pole to raise money to protect children from cruelty.

    - by jessica.ebbelaar
    Hi, my name is Luca. I joined Oracle in 2005 and I am currently working as a Dell EMEA Channel Manager UK, Ireland and Iberia and I am responsible for the Oracle Dell relationship for the above 3 countries. On the 31st of March 2011 I will set out to complete the ultimate challenge. I will walk and ski across the frozen Arctic to the Top of The World: the GEOGRAPHIC North Pole. While dragging all my supplies over 60 Nautical miles of moving sea ice, in temperatures as low as minus 30 degrees Celsius. I will spend 8 to 10 days preparing, working, living and travelling to the North Pole to 90 degree north. In November I spent a full week of training for this trip.( watch my video). This gave me the opportunity to meet the rest of the team, testing all the gear and carrying an 18inch tyre around the country side for 8 hours per day. I am honored to embark this challenging journey to support the National Society for the Prevention of Cruelty to Children (NSPCC). The NSPCC helped more than 750,000 young people to speak out for the first time about abuse they had suffered. I am a firm believer that in order to build a stronger, healthier and wiser society we need to support and help future generations from the beginning of their life journey. This is why cruelty to children must stop. FULL STOP.   Through Virgin Money Giving, you can sponsor me and donations will be quickly processed and passed to NSPCC. Virgin Money Giving is a non-profit organization and will claim gift aid on a charity's behalf where the donor is eligible for this. If you are a UK tax payer please don't forget to select Gift Aid. Gift Aid is great because it means charities get extra money added to their donations at no extra cost to the donor. For every £1 donated, the charity currently receives £1.28 when you add Gift Aid. Anyone who would like to find out more can visit my Facebook page ‘Luca North Pole charity fundraising trip’ I really appreciate all your support and thank you for supporting the NSPCC.

  • JavaScript Sucks.

    - by Matt Watson
    JavaScript Sucks. Yes, I said it. Microsoft's announcement of TypeScript got me thinking today. Is this a step in the right direction? It sounds like it fixes a lot of problems with JavaScript development. But is it really just duct tape and super glue for a programming model that needs to be replaced?I have had a love hate relationship with JavaScript, like most developers who would prefer avoiding client side code. I started doing web development over 10 years ago and I have done some pretty cool stuff with JavaScript. It has came a long ways and is the universal standard these days for client side scripting in the web browser. Over the years the browsers have become much faster at processing JavaScript. Now people are even trying to use it on the server side via node.js. OK, so why do I think JavaScript sucks?Well first off, as an enterprise web application developer, I don't like any scripting or dynamic languages. I like code that compiles for lots of obvious reasons. It is messy to code with and lacks all kinds of modern programming features. We spend a lot of time trying to hack it to do things it was never really designed for.Ever try to use different jQuery based plugins that require conflicting jQuery versions? Yeah, that sucks.How about trying to figure out how to make 20 javascript include files load quicker as one request? Yeah that sucks too.Performance? Let me just point to the old Facebook mobile app made with JS & HTML5. It sucked. Enough said.How about unit testing JavaScript? I've never tried it, but it sure sounds like fun.My biggest problem with JavaScript is code security. If I make some awesome product, there is no way to protect my code. How can we expect game makers to write apps in 100% JavaScript and HTML5 if they can't protect their intellectual property?There are compiling tools like Closure, unit test frameworks, minify, coffee script, TypeScript and a bunch of other tools. But to me, they all try to make up for the weaknesses and problems with JavaScript. JavaScript is a mess and we spend a lot of time trying to work around all of it's problems. It is possible to program in Silverlight, Java or Flash and run that in the browser instead of JavaScript, but they all have their own problems and lack universal mobile support. I believe Microsoft's new TypeScript is a step forward for JavaScript, but I think we need to start planning to go a whole different direction. We need a new universal client side programming model, because JavaScript sucks.

  • I Choose iNada

    - by Mark Treadwell
    As a laptop and Kindle user, I have been looking at the usual cyclical Apple frenzy in the press with the same kind of amused tolerance I give my three-year-old son.  They never seem to learn, and they keep repeating the same things.  However when I ready articles like this, I am reminded that that is not always the case. I am a happy user of a monster-sized HP HDX laptop, HP touch screen all-in-one system, and multi-screen Dell desktops at home as well as a HP business laptop at work.  I have no iPod, iMac, iTouch or any other relationship with the company who wants to trademark the prefix “i”. I have not missed them. That is not to say that I have no technological gadgets.  I do.  They just do not dominate Every company wants to preserve their customer base, but Apple just does it too rigidly.  The buy-in necessary rubs me wrong.  When the fanboys scream about the next great iApple thing which will kill off another market segment (this time, the iPad will kill off laptops), the amused tolerance returns. From what I have seen, the iPad virtual keyboard is a poor substitute for an actual keyboard.  It was intended to let you get some kind of text into a device that is not really intended for keyboard input, but rather for touch manipulation of a designed interface.  I like the virtual keyboard on my LG Dare cell phone, but you will not catch me writing my next novel with it.  But, you hear, you can connect a real keyboard and get info from another computer.  That is when you realize that the iPad is not a true standalone device like a laptop.  You have to make more hardware purchases to get what you truly want.  It is an expensive accommodation to get you a different form of freedom. So if Apple made a product with me in mind, you can have it.  Everyone gets to make their own choice.  My choice is the iNada.

  • Managing Social Relationships for the Enterprise – Part 1

    - by Michael Hylton
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Reggie Bradford, Senior Vice President, Oracle Today, Mark Hurd, President of Oracle, Thomas Kurian, Executive Vice President of Oracle and I discussed the strategic importance of how social media is impacting the enterprise and how it is changing the way customers, prospects employees and investors interact with brands worldwide. Oracle understands that the consumer is in control and as such, brands must evolve and change to meet growing needs. In addition, according to social media thought leader and Analyst from Altimeter Group, Jeremiah Owyang, companies now average 178 corporate-owned social media accounts. When Oracle added leading social marketing, listening analytics and development tools from Vitrue, Collective Intellect and Involver to its Oracle’s Cloud Services Suite we went beyond providing a single set of tools. We developed an entire framework to include a comprehensive social relationship management suite to help companies move beyond the social enterprise and achieve the social-enabled enterprise. The fundamental shift from transaction to engagement means that enterprises need not only a social strategy, but should also ensure that the information and data received from social initiatives flow back to marketing, sales, support and service. Doing so enables companies to deliver a proactive and compelling experience and provides analytics to turn engagement into opportunity – and ultimately that opportunity into revenue. On September 13, 2012, I am delighted to sit down with Jeremiah to further the discussion about how enterprises are addressing social media strategies and managing content. In addition, we will be taking your questions after the webinar via Twitter (@Oracle, @ReggieBradford, @cwfinn, @jowyang). Use #oracle and #socbiz to submit questions and follow the conversation. I look forward to speaking with you and answering your questions online. For more information about becoming a social-enabled enterprise, visit www.oracle.com/social.

  • What Problems Are Better Solved By SOAP Over REST?

    In the battle for web service supremacy SOAP and REST have been battling for years. In my personal opinion this debate should have never existed. Yes, both forms can be used to create an interactive web service, but each form of a service was developed independent of each other to solve two different yet similar problems. Based my research and experience I would have to say that REST should be the preferred web service methodology and SOAP should only be used in specific situations. Note, I did not say that I was against SOAP, and in fact I actually like to use SOAP when it is needed. Criteria for using SOAP: Does the service need a guaranteed level of reliability and security? Did the provider and consumer of the service agreed on a standardized data exchange format? Does the service need data context and state management? If you answer yes to any of these questions, then you may want to consider SOAP as the format for the web service. Another way to look at the relationship between REST and SOAP is to look at the medical field.  For most things a general doctor or you family health care provider can acceptably treat most conditions from the case of a common cold to a broken bone. A general doctor more aligns with REST in my opinion because for most service requirements REST fulfills a projects needs, but what happens if you need more of an advanced examination, you would go to a specialist. A specialist would already have experience dealing with specific issues that you are experiencing giving them specific context to how best treat you going forward. SOAP acts more like a specialist doctor giving that they understand the context of an issue and can treat it based on the state of other patients they have already treated. An example of where I would use SOAP over REST in real life would be a single sign-on application. I n these cases I need to check validate a username and password for authentication and authorization of a web page request. This service would need to maintain state while it authenticated a user and while it validated access to a web page on a subsequent request. This service must process every request for access and not allow caching to ensure that every request is processed and the appropriate users are allowed to view selected web pages.

  • Creating metadata value relationships

    - by kyle.hatlestad
    I was recently asked an question about an interesting use case. They wanted content to be submitted into UCM with a particular ID in a custom metadata field. But they wanted that ID to be translated during submission into an employee name in another metadata field upon submission. My initial thought was that this could be done with a dependent choice list (DCL). One option list field driving the choices in another. But this didn't work in this case for a couple of reasons. First, the number of IDs could potentially be very large. So making that into a drop-down list would not be practical. The preference would be for that field to simply be a text field to type in the ID. Secondly, data could be submitted through different methods other then the web-based check-in form. And without an interface to select the DCL choices, the system needed a way to determine and populate the name field. So instead I went the approach of having the value of the ID field drive the value of the Name field using the derived field approach in my rule. In looking at it though, it was easy to simply copy the value of the ID field into the Name field...but to have it look up and translate the value proved to be the tricky part. So here is the approach I took... First I created my two metadata fields as standard text fields in the Configuration Manager applet. Next I create a table that stores the relationship between the IDs and Names. I then create a View into that table and set the column to the EmployeeID. I now create a new Application Field and set it as an option list using the View I created in the previous step. The reason I create it as an Application field is because I don't need to display the field or store a value in it. I simply need to make use of the option list in the next step... Finally, I create a Rule in which I select the Employee Name field and turn on the 'Is derived field' checkbox. I edit the derived value and add a new condition. Because the option list is a Application field and not an Information field, I can't use the Compute button. Instead, I insert this line directly in the Value field: @getFieldViewValue("EmployeeMapping",#active.xEmployeeID, "EmployeeName") The "EmployeeMapping" parameter designates that the value should be pulled from the EmployeeMapping Application field that I had created in the previous step. The #active.xEmployeeID field is the ID value that should be pulled from what the user entered. "EmployeeName" is the column name in the table which has the value which corresponds to the ID. The extracted name then becomes the value within our Employee Name field. That's it. You can then add additional Rules to make the Name field read-only/hidden on the check-in page and such.

  • Tips On Using The Service Contracts Import Program

    - by LuciaC
    Prior to release 12.1 there was no supported way to import contracts into the EBS Service Contracts application - there were no public APIs nor contract load programs provided.  From release 12.1 onwards the 'Service Contracts Import Program' is provided to load service contracts into the application. The Service Contracts Import functionality is explained in How to Use the Service Contracts Import Program - Scope and Limitations (Doc ID 1057242.1).  This note includes an attached document which explains the program architecture, shows the Entity Relationship Diagram and details the interface table definitions. The Import program takes data from the interface tables listed below and populates the contracts schema tables:  OKS_USAGE_COUNTERS_INTERFACE OKS_SALES_CREDITS_INTERFACEOKS_NOTES_INTERFACEOKS_LINES_INTERFACEOKS_HEADERS_INTERFACEOKS_COVERED_LEVELS_INTERFACEThese interface tables must be loaded via a custom load program.The Service Contracts Import concurrent request is then submitted to create contracts from this legacy data. The parameters to run the Import program are:  Parameter Description  Mode Validate only, Import  Batch Number Batch_Id (unique id populated into the OKS_HEADERS_INTERFACE table)  Number of Workers Number of workers required (these are spawned as separate sub-requests)  Commit size Represents number of successfully processed contracts commited to database The program spawns sub-requests for the import worker(s) and the 'Service Contracts Import Report'.  The data is validated prior to import and into the Contracts tables and will report errors in the Service Contracts Import Report program output file (Import Execution Report).  Troubleshooting tips are provided in R12.1 - Common Service Contract Import Errors (Doc ID 762545.1); this document lists some, but not all, import errors.  The document will be updated over time.  Additional help is given in Debugging Tip for Service Contracts Import Errors (Doc ID 971426.1).After you successfully import contracts, you can purge the records from the interface tables by running the Service Contracts Import Purge concurrent program. Note that there is no supported way to mass delete data from the Contracts schema tables once they are populated, so data loaded by the Import program must be fully tested and verified before the program is run to load data into a Production system.A Service Contracts Import Test program has been provided which will take an existing contract in the application and load the interface tables using the data from that contract.  This can be used as an example for guidance on how to load the interface tables.  The Test program functionality is explained in How to Use the Service Contracts Test Import Program Provided in Release 12.1 (Doc ID 761209.1).  Note that the Test program has some limitations which do not apply to the full Import program and is not a supported program, it is simply a testing tool.

  • How To Build An Enterprise Application - Introduction

    - by Tuan Nguyen
    An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure

  • TechEd 2010 Day Three: The Database Designer (Isn't)

    - by BuckWoody
    Yesterday at TechEd 2010 here in New Orleans I worked the front-booth, answering general SQL Server questions for the masses. I was actually a little surprised to find most of the questions I got were from folks that wanted to know more about Stream Insight and Master Data Services. In past conferences I've been asked a lot of "free consulting" questions, about problems folks have had from older products. I don't mind that a bit - in fact, I'm always happy to help in any way I can. But this time people are really interested in the new features in the product, and I like that they are thinking ahead, not just having to solve problems in production. My presentation was on "Database Design in an Hour". We had the usual fun, and SideShow Bob made an appearance - I kid you not. The guy in the back of the room looked just like Sideshow Bob, so I quickly held a "bes thair" contest, and he won. Duing the presentation, I explain the tools you can use to design databases. I also explain that the "Database Designer" tool in SQL Server Management Studio (SSMS) isn't truly a desinger - it uses non-standard notation, doesn't have a meta-data dictionary, and worst of all, it works at the physical level. In other words, whatever you do in SSMS will automatically change the field/table/relationship structures in the database. We fixed this in SSMS 2008 and higher by adding an option to block that, but the tool is not a good design function nonetheless. To be fair, no one I know of at Microsoft recommends that it is - but I was shocked to hear so many developers in the room defending it as a good tool. I think the main issue for someone who doesn't have to work with Relational Systems a great deal is that it can be difficult to figure out Foreign Keys. The syntax makes them look "backwards", so it's just easier to grab a field and place it on the table you want to point to. There are options. You can download a couple of free tools (CA has a community edition of ER-WIN, Quest has one, and Embarcadero also has one) and if you design more than one or two databases a year, it may be worth buying a true design tool. For years I used Visio, but we changed it so that it doesn't forward-engineer (create the DDL) any more, so it isn't a true design tool either. So investigate those free and not-so-free tools. You'll find they help you in your job - but stay away from the Database Designer in SSMS. Or I'll send Sideshow Bob over there to straighten you out.

The way we work and connect with our customers is changing dramatically and this means re-thinking how we secure the interaction and enable the experience. Work is an activity not a place - mobile access enables employees to work from any device anywhere and anytime. Organizations are utilizing "flash teams" - instead of a dedicated group to solve problems, organizations utilize more cross-functional teams. Work is now social - email collaboration will be replaced by dynamic social media style interaction.

  • Interview with Koen Aben, Supply Chain Director of WE Fashion

    - by user801960
    We recently spoke to Koen Aben, the Supply Chain Director of WE Fashion, who gave us some insight into how Oracle supported the international fashion retailer through the completion of a large scale integration project across its 340 European stores. Koen explains the reasoning behind the project which was to create a common retail foundation and to integrate and align working processes to drive insight and enable continued growth. It is always good to hear from someone of Koen’s experience who can articulate the benefits of partnering with the right company for such an extensive project as this. Koen explains that a crucial element of such a project is to unify business applications into a common platform, adding that for successful growth, retailers really need to achieve enterprise-wide alignment. At the start of the three year project, WE Fashion’s application platform was fragmented impacting the company’s ability to support sustained growth. In light of this, WE Fashion invested in its processes, systems, teams and partnerships to build the needed retail foundation. Now after successfully completing the project, the basis is in place to ensure that growth is unimpeded. In the video, Koen Aben highlights some of the factors necessary for the success of the project as: Having an understanding that the process of creating a growth platform for a company is a long journey Accepting that during a lengthy project such as this, there will be high and low points experienced within the project team and the business, but that the relationship with your partners is crucial to the success of the project. Having the correct team in place will prove to be the “lynch –pin” of any successful project Oracle supported Koen and his team in implementing this project, and is recognised for the role it played during this development in partnership with the company. On his experience with working with the Oracle team, Koen points out that in the critical situations, Oracle was there to ensure that the right people were in place whenever needed and this was key to ensuring the project’s success. Since Oracle is one of the few providers that can offer an enterprise-wide retail platform, our best practice approach is key to connecting interactions throughout the business to enable insight and optimise operations. This is a great example of a large scale international retail project, where the true success of its completion is reflected in how proud the company is about what has been achieved, and the fact that results are already being seen.

  • What are the tradeoffs for using 'partial view models'?

    - by Kenny Evitt
    I've become aware of an itch due to some non-DRY code pertaining to view model classes in an (ASP.NET) MVC web application and I'm thinking of scratching my itch by organizing code in various 'partial view model' classes. By partial-view-model, I'm referring to a class like a view model class in an analogous way to how partial views are like views, i.e. a way to encapsulate common info and behavior. To strengthen the 'analogy', and to aid in visually organizing the code in my IDE, I was thinking of naming the partial-view-model classes with a _ prefix, e.g. _ParentItemViewModel. As a slightly more concrete example of why I'm thinking along these lines, imagine that I have a domain-model-entity class ParentItem and the user-friendly descriptive text that identifies these items to users is complex enough that I'd like to encapsulate that code in a method in a _ParentItemViewModel class, for which I can then include an object or a collection of objects of that class in all the view model classes for all the views that need to include a reference to a parent item, e.g. ChildItemViewModel can have a ParentItem property of the _ParentItemViewModel class type, so that in my ChildItemView view, I can use @Model.ParentItem.UserFriendlyDescription as desired, like breadcrumbs, links, etc. Edited 2014-02-06 09:56 -05 As a second example, imagine that I have entity classes SomeKindOfBatch, SomeKindOfBatchDetail, and SomeKindOfBatchDetailEvent, and a view model class and at least one view for each of those entities. Also, the example application covers a lot more than just some-kind-of-batches, so that it wouldn't really be useful or sensible to include info about a specific some-kind-of-batch in all of the project view model classes. But, like the above example, I have some code, say for generating a string for identifying a some-kind-of-batch in a user-friendly way, and I'd like to be able to use that in several views, say as breadcrumb text or text for a link. As a third example, I'll describe another pattern I'm currently using. I have a Contact entity class, but it's a fat class, with dozens of properties, and at least a dozen references to other fat classes. However, a lot of view model classes need properties for referencing a specific contact and most of those need other properties for collections of contacts, e.g. possible contacts to be referenced for some kind of relationship. Most of these view model classes only need a small fraction of all of the available contact info, basically just an ID and some kind of user-friendly description (i.e. a friendly name). It seems to be pretty useful to have a 'partial view model' class for contacts that all of these other view model classes can use. Maybe I'm just misunderstanding 'view model class' – I understand a view model class as always corresponding to a view. But maybe I'm assuming too much.

  • Explanation of the definition of interface inheritance as described in GoF book

    - by Geek
    I am reading the first chapter of the Gof book. Section 1.6 discusses about class vs interface inheritance: Class versus Interface Inheritance It's important to understand the difference between an object's class and its type. An object's class defines how the object is implemented.The class defines the object's internal state and the implementation of its operations.In contrast,an object's type only refers to its interface--the set of requests on which it can respond. An object can have many types, and objects of different classes can have the same type. Of course, there's a close relationship between class and type. Because a class defines the operations an object can perform, it also defines the object's type . When we say that an object is an instance of a class, we imply that the object supports the interface defined by the class. Languages like c++ and Eiffel use classes to specify both an object's type and its implementation. Smalltalk programs do not declare the types of variables; consequently,the compiler does not check that the types of objects assigned to a variable are subtypes of the variable's type. Sending a message requires checking that the class of the receiver implements the message, but it doesn't require checking that the receiver is an instance of a particular class. It's also important to understand the difference between class inheritance and interface inheritance (or subtyping). Class inheritance defines an object's implementation in terms of another object's implementation. In short, it's a mechanism for code and representation sharing. In contrast,interface inheritance(or subtyping) describes when an object can be used in place of another. I am familiar with the Java and JavaScript programming language and not really familiar with either C++ or Smalltalk or Eiffel as mentioned here. So I am trying to map the concepts discussed here to Java's way of doing classes, inheritance and interfaces. This is how I think of of these concepts in Java: In Java a class is always a blueprint for the objects it produces and what interface(as in "set of all possible requests that the object can respond to") an object of that class possess is defined during compilation stage only because the class of the object would have implemented those interfaces. The requests that an object of that class can respond to is the set of all the methods that are in the class(including those implemented for the interfaces that this class implements). My specific questions are: Am I right in saying that Java's way is more similar to C++ as described in the third paragraph. I do not understand what is meant by interface inheritance in the last paragraph. In Java interface inheritance is one interface extending from another interface. But I think the word interface has some other overloaded meaning here. Can some one provide an example in Java of what is meant by interface inheritance here so that I understand it better?

  • The Case for Complimentary Software Copies

    - by GGBlogger
    As the Geriatric Geek you can understand that I’ve been writing and studying for over 60 years. That means that I’ve seen insane changes in the computer software industry. I’ve made the joke that I get a new college education every 6 months or so. Of course that’s an exaggeration but it doesn’t make the feeling go away. I have a long standing and strong relationship with Microsoft so I’m armed with virtually every tool they make. It also means that I have access to tons of training material. But here’s the rub… Last year I started a definitive read of Professional Visual Basic 2008. The purpose was to fill in holes in my understanding of various things. I’m currently on page 1119 of some 1400 pages. During this sojourn I’ve decided that the future is web related which is to say that the future of “thick client” applications running as Windows applications is likely to slowly disappear. To that end I’ve taken a side trip or two into the world of ASP (including XML), Silverlight and cloud development. After carefully avoiding (that’s tongue in cheek) XML for years I finally had to bite the bullet, so to speak, and start learning XML in earnest. The most recent result of that was trail downloads of Altova’s MissionKit 2010 for Software Architects and Liquid Technologies Liquid XML Studio Developer Edition. These are both beautiful products and I want to learn them and write about them. Now comes the rub… While 30 day evaluations are generous in allowing casual users to assess these technologies for purchase they are NOT long enough to allow an author to evaluate, learn and ultimately write about them. Even if I devoted the full 30 days to learning, using and writing about say Altova’s suite I wouldn’t have enough time. Liquid XML may be a little easier to learn (one product as opposed to 8).  Add to that the fact that I frequently get sidetracked to add to my kit and it really blows out. It can be extremely frustrating when I’ve devoted hours to a project and suddenly discover that to complete it I will either need to purchase a license or abandon the project. Since my life blood does not depend on the product I end up abandoning the project and moving on. So to the folks from whom I request complimentary copies… I guarantee that if I convert your product to doing paid development work I will purchase a license to do that but as long as I am using your product to study for the purpose of writing samples, teaching use or otherwise promoting your product to other paying customers I will ask that you give me a license so that I can do that without facing the dread expiration of a 30 day trial.

  • Failing report subscriptions

    - by DavidWimbush
    We had an interesting problem while I was on holiday. (Why doesn't this stuff ever happen when I'm there?) The sysadmin upgraded our Exchange server to Exchange 2010 and everone's subscriptions stopped. My Subscriptions showed an error message saying that the email address of one of the recipients is invalid. When you create a subscription, Reporting puts your Windows user name into the To field and most users have no permissions to edit it. By default, Reporting leaves it up to exchange to resolve that into an email address. This only works if Exchange is set up to translate aliases or 'short names' into email addresses. It turns out this leaves Exchange open to being used as a relay so it is disabled out of the box. You now have three options: Open up Exchange. That would be bad. Give all Reporting users the ability to edit the To field in a subscription. a) They shouldn't have to, it should just work. b) They don't really have any business subscribing anyone but themselves. Fix the report server to add the domain. This looks like the right choice and it works for us. See below for details. Pre-requisites: A single email domain name. A clear relationship between the Windows user name and the email address. eg. If the user name is joebloggs, then joebloggs@domainname needs to be the email address or an alias of it. Warning: Saving changes to the rsreportserver.config file will restart the Report Server service which effectively takes Reporting down for around 30 seconds. Time your action accordingly. Edit the file rsreportserver.config (most probably in the folder ..\Program Files[ (x86)]\Microsoft SQL Server\MSRS10_50[.instancename]\Reporting Services\ReportServer). There's a setting called DefaultHostName which is empty by default. Enter your email domain name without the leading '@'. Save the file. This domain name will be appended to any destination addresses that don't have a domain name of their own.

  • How to get tens of millions of pages indexed by Google bot?

    - by Chris Adragna
    We are currently developing a site that currently has 8 million unique pages that will grow to about 20 million right away, and eventually to about 50 million or more. Before you criticize... Yes, it provides unique, useful content. We continually process raw data from public records and by doing some data scrubbing, entity rollups, and relationship mapping, we've been able to generate quality content, developing a site that's quite useful and also unique, in part due to the breadth of the data. It's PR is 0 (new domain, no links), and we're getting spidered at a rate of about 500 pages per day, putting us at about 30,000 pages indexed thus far. At this rate, it would take over 400 years to index all of our data. I have two questions: Is the rate of the indexing directly correlated to PR, and by that I mean is it correlated enough that by purchasing an old domain with good PR will get us to a workable indexing rate (in the neighborhood of 100,000 pages per day). Are there any SEO consultants who specialize in aiding the indexing process itself. We're otherwise doing very well with SEO, on-page especially, besides, the competition for our "long-tail" keyword phrases is pretty low, so our success hinges mostly on the number of pages indexed. Our main competitor has achieved approx 20MM pages indexed in just over one year's time, along with an Alexa 2000-ish ranking. Noteworthy qualities we have in place: page download speed is pretty good (250-500 ms) no errors (no 404 or 500 errors when getting spidered) we use Google webmaster tools and login daily friendly URLs in place I'm afraid to submit sitemaps. Some SEO community postings suggest a new site with millions of pages and no PR is suspicious. There is a Google video of Matt Cutts speaking of a staged on-boarding of large sites, too, in order to avoid increased scrutiny (at approx 2:30 in the video). Clickable site links deliver all pages, no more than four pages deep and typically no more than 250(-ish) internal links on a page. Anchor text for internal links is logical and adds relevance hierarchically to the data on the detail pages. We had previously set the crawl rate to the highest on webmaster tools (only about a page every two seconds, max). I recently turned it back to "let Google decide" which is what is advised.

  • Business Insight, IT Execution: 9 Project Management Tips

    - by Sylvie MacKenzie, PMP
    Excerpt from Profit Magazine - by David Rosenbaum When Marcos Baccetto was first asked to be the business-side project lead on Eaton Corporation’s Vehicle Group South America (VGSA) Oracle project, the operations services manager responsible for running manufacturing was, he confesses, “a little afraid” because of his lack of IT experience. Today, Baccetto calls the project “a fantastic experience,” and he is a true believer in the benefits of a close relationship between IT implementers and their line-of-business peers. Through his partnership with Jesiele Lima, then VGSA IT manager, Baccetto and Eaton’s South American operations team came to understand several important principles of business and IT. Here he shares nine tips managers should consider when working on an enterprise technology project. 1. Make it a business project, not an IT project. All levels of functional management must have ownership, responsibility, and accountability for the success of the implementation. 2. Share responsibility. Business owners should sign off on tests and data conversion. 3. Clean your data. Dedicating a team to improve core data quality prior to project launch can be a significant time-saver. 4. Select resources properly. Have functional people who can translate business needs to IT and can influence organizational change. 5. Manage scope. Follow project management methodologies and disciplines. 6. Adopt common processes, global solutions. Avoid customized, local solutions. The big-picture business goals can get lost in the details. 7. Implement processes prior to the go-live date. Change management can be key. Keep the workforce informed and train users in advance. 8. Define metrics milestones. Assume there will be a crisis during deployment. Having baseline metrics to compare against will help implementers keep their cool—and the project moving forward. 9. The sponsor’s commitment is critical. It is needed to support the truly difficult decisions.

  • In an Entity-Component-System Engine, How do I deal with groups of dependent entities?

    - by John Daniels
    After going over a few game design patterns, I have settle with Entity-Component-System (ES System) for my game engine. I've reading articles (mainly T=Machine) and review some source code and I think I got enough to get started. There is just one basic idea I am struggling with. How do I deal with groups of entities that are dependent on each other? Let me use an example: Assume I am making a standard overhead shooter (think Jamestown) and I want to construct a "boss entity" with multiple distinct but connected parts. The break down might look like something like this: Ship body: Movement, Rendering Cannon: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled Core: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled, Disabling (er...destroying) all other entities in the ship group My goal would be something that would be identified (and manipulated) as a distinct game element without having to rewrite subsystem form the ground up every time I want to build a new aggregate Element. How do I implement this kind of design in ES System? Do I implement some kind of parent-child entity relationship (entities can have children)? This seems to contradict the methodology that Entities are just empty container and makes it feel more OOP. Do I implement them as separate entities, with some kind of connecting Component (BossComponent) and related system (BossSubSystem)? I can't help but think that this will be hard to implement since how components communicate seem to be a big bear trap. Do I implement them as one Entity, with a collection of components (ShipComponent, CannonComponents, CoreComponent)? This one seems to veer way of the ES System intent (components here seem too much like heavy weight entities), but I'm know to this so I figured I would put that out there. Do I implement them as something else I have mentioned? I know that this can be implemented very easily in OOP, but my choosing ES over OOP is one that I will stick with. If I need to break with pure ES theory to implement this design I will (not like I haven't had to compromise pure design before), but I would prefer to do that for performance reason rather than start with bad design. For extra credit, think of the same design but, each of the "boss entities" were actually connected to a larger "BigBoss entity" made of a main body, main core and 3 "Boss Entities". This would let me see a solution for at least 3 dimensions (grandparent-parent-child)...which should be more than enough for me. Links to articles or example code would be appreciated. Thanks for your time.

  • Oracle OpenWorld Call for MDM Papers

    - by david.butler(at)oracle.com
    As the MDM Track owner, I would like to invite everyone to respond to the Oracle OpenWorld (October 2-6, Moscone Center, San Francisco) Call for Papers (https://oracleus.wingateweb.com/portal/cfp/ ). The Call for Papers is open now through Sunday, March 27. This is an outstanding opportunity for organizations familiar with MDM to tell their story to a very large, knowledgeable and intensely interested community. Opportunities for feedback and networking abound.  I would love to see MDM papers on: business drivers; business benefits; quantified ROI stories; business process optimization; implementation styles; implementation lessons learned; using master data as a service; data governance best practices; end-to-end data quality experiences; support for SOA; Chart of Accounts issues fixed; how to leverage reference data; improving EPM and/or BI across the board; operationalizing a data warehouse; support for cloud computing; compliance success stories; architecture, scalability, and mixed workload RAC platform performance examples; industry specific value propositions (Financial Services; Retail, Telecom; Manufacturing, High Tech Manufacturing, Public Sector, Health Care, …); and line of business specific value propositions (CRM, ERP, PLM, SCM, …); etc. In fact, given that MDM positively impacts all areas of operations and analytics, there are no limits to the ideas you may have for an OpenWorld presentation. When you follow the submission process, be sure to use “Master Data Management” for either the Primary or Optional track. Add “Master Data Management” as an Optional track if you are adding MDM content to a presentation on one of the following tracks: Agile; Customer Relationship Management, Oracle E-Business Suite, Product Lifecycle Management, Siebel, Sourcing and Procurement, Supply Chain Management, or one of the 18 available industry tracks. If Cloud Computing is included, please add “Cloud Computing” as a Cross-Stream Track. And don’t forget to make “MDM” a Tag, along with Business Intelligence, Cloud, CRM, Data Integration, Data Migration, Data Warehousing, EPM, or Service-Oriented Architecture whenever your content includes these items. I will personally review each submission. I hope you all keep me very busy over the next few weeks.

  • Who should control navigation in an MVVM application?

    - by SonOfPirate
    Example #1: I have a view displayed in my MVVM application (let's use Silverlight for the purposes of the discussion) and I click on a button that should take me to a new page. Example #2: That same view has another button that, when clicked, should open up a details view in a child window (dialog). We know that there will be Command objects exposed by our ViewModel bound to the buttons with methods that respond to the user's click. But, what then? How do we complete the action? Even if we use a so-called NavigationService, what are we telling it? To be more specific, in a traditional View-first model (like URL-based navigation schemes such as on the web or the SL built-in navigation framework) the Command objects would have to know what View to display next. That seems to cross the line when it comes to the separation of concerns promoted by the pattern. On the other hand, if the button wasn't wired to a Command object and behaved like a hyperlink, the navigation rules could be defined in the markup. But do we want the Views to control application flow and isn't navigation just another type of business logic? (I can say yes in some cases and no in others.) To me, the utopian implementation of the MVVM pattern (and I've heard others profess this) would be to have the ViewModel wired in such a way that the application can run headless (i.e. no Views). This provides the most surface area for code-based testing and makes the Views a true skin on the application. And my ViewModel shouldn't care if it displayed in the main window, a floating panel or a child window, should it? According to this apprach, it is up to some other mechanism at runtime to 'bind' what View should be displayed for each ViewModel. But what if we want to share a View with multiple ViewModels or vice versa? So given the need to manage the View-ViewModel relationship so we know what to display when along with the need to navigate between views, including displaying child windows / dialogs, how do we truly accomplish this in the MVVM pattern?

  • Cloud Computing: Start with the problem

    - by BuckWoody
    At one point in my life I would build my own computing system for home use. I wanted a particular video card, a certain set of drives, and a lot of memory. Not only could I not find those things in a vendor’s pre-built computer, but those were more expensive – by a lot. As time moved on and the computing industry matured, I actually find that I can buy a vendor’s system as cheaply – and in some cases far more cheaply – than I can build it myself.   This paradigm holds true for almost any product, even clothing and furniture. And it’s also held true for software… Mostly. If you need an office productivity package, you simply buy one or use open-sourced software for that. There’s really no need to write your own Word Processor – it’s kind of been done a thousand times over. Even if you need a full system for customer relationship management or other needs, you simply buy one. But there is no “cloud solution in a box”.  Sure, if you’re after “Software as a Service” – type solutions, like being able to process video (Windows Azure Media Services) or running a Pig or Hive job in Hadoop (Hadoop on Windows Azure) you can simply use one of those, or if you just want to deploy a Virtual Machine (Windows Azure Virtual Machines) you can get that, but if you’re looking for a solution to a problem your organization has, you may need to mix Software, Infrastructure, and perhaps even Platforms (such as Windows Azure Computing) to solve the issue. It’s all about starting from the problem-end first. We’ve become so accustomed to looking for a box of software that will solve the problem, that we often start with the solution and try to fit it to the problem, rather than the other way around.  When I talk with my fellow architects at other companies, one of the hardest things to get them to do is to ignore the technology for a moment and describe what the issues are. It’s interesting to monitor the conversation and watch how many times we deviate from the problem into the solution. So, in your work today, try a little experiment: watch how many times you go after a problem by starting with the solution. Tomorrow, make a conscious effort to reverse that. You might be surprised at the results.
