• Oracle Announces Availability of Oracle Exaskeleton with Extreme Scale

  - by Bruce Tierney

  The World’s First Human Scale Body Surface (HSBS) Designed to Toughen Spineless Wimps April 1, 2012 Building on the success of Oracle Exalogic, Oracle Exadata, and Oracle Exalytics, Oracle today announced the general availability of Oracle Exaskeleton, toughening up spineless wimps across the globe through the introduction of extreme scalability over the human body leveraging a revolutionary new technology called Human Scale Body Surface (HSBS). First Customer Ship (FCS) was received by the little known and mostly unsuccessful superhero Awkwardman. After applying Oracle Exaskeleton with extreme scale, he has since rebranded himself as Aquaman. Said Aquaman, “I used to feel so helpless in my skin…now I feel like…well…a highly scaled Engineered System thanks to Oracle!” Thousand of meek and mild individuals eagerly lined up outside Oracle Corporation’s Redwood Shores office to purchase the new Oracle Exaskeleton, with the hope of finally gaining the spine they never had. Unfortunately for the individuals, a bully was spotted allegedly kicking the sand covering the beaches of Redwood Shores into the still spineless Exaskeleton hopefuls. Supporting Quotes “Industry analysts are inquiring if Oracle Exaskeleton is a radical departure from Oracle’s traditional enterprise focus into new markets”, said Oracle representative Sabrina Twich, “Oracle has extensive expertise in unified backbone solutions for application infrastructures…this is simply a new port to the human body combining our Business Intelligence (BI) and RDBC (Remote Direct Brain Cell) technologies.” “With this release of Oracle Exaskeleton, Oracle has redefined scalability. Software and hardware vendors had it all wrong” said the Director of Oracle Exaskeleton, “Scalability for hardware is like…um…you know…so scale-ful. No, wait…can I say that again? I didn’t get that right…Scalability is hardware-on-demand with public and private…hybrid clouds, no…<long pause>…Scalability for… nevermind, I don’t want to be in this stupid press release anyway” Releases An upcoming Oracle Exaskeleton service pack release will include a new datasheet with an extensive library of three-letter acronyms (TLAs) as well as the introduction of more four-letter acronyms (FLAs) since technologies vendors have used up almost all of the 17,576 TLA permutations (TLAPs). About Oracle Oracle engineers hardware and software to work together in the cloud and in your data center. It would be an amazing coincidence if any of this is true in some secret Oracle lab, but I doubt it. Trademarks Really…you’re still reading this? Cool!

• Advice on selecting programming languages to concentrate on? (2nd year IT security student)

  - by Tyler J Fisher

  I'm in the process of considering which programming languages I should devote the majority of my coding studies to. I'm a 2nd year CS student, majoring in IT security. What I want to do/work with: Intelligence gathering Relational databases Virus design Snort network IPS Current coding experience (what I'm going to keep): Java - intermediate HTML5 - intermediate SQL (MySQL, Oracle 11g) - basic BASH - basic I'm going to need to learn (at least) one of the following languages in order to be successful in my field. Languages to add (at least 1): Ruby (+Metasploit) C++ (virus design, low-level driver interaction, computationally intensive applications) Python (import ALL the things) My dilemma: If I diversify too broadly, I won't be able to focus on, and improve in a specific niche. Does anyone have any advice as to how I should select a language? What I'm considering + why I'm leaning towards Ruby because of Metasploit support, despite lower efficiency when compared to Python. Any suggestions based on real-world experience? Should I focus on Ruby, Python, or C++? Both Ruby, and Python have been regarded as syntactically similar to Java which my degree is based around. I'm going to be studying C++ in two years as a component of my malicious code class. Thanks, Tyler

• Structuring database for multi-object "activity" and "following" functionalities

  - by romaninsh

  I am working on a web application which operate with different types of objects such as user, profiles, pages etc. All objects have unique object_id. When objects interact it may produce "activity", such as user posting on the page or profile. Activity may be related to multiple objects through their object_id. Users may also follow "objects" and they need to be able to see stream of relevant activity. Could you provide me with some data structure suggestions which would be efficient and scalable? My goal is to show activity limited to the objects which user is following I am not limited by relational databases. Update As I'm getting advices on ORM and how index things, I'd like to again, stress my question. According to my current design model the database structure looks like this: As you can see - it's quite easy to implement database like that. Activity and Follower tables do contain much larger amount of records than the upper level but it's tolerable. But when it comes for me to create a "timeline" table, it becomes a nightmare. For every user I need to reference all the object activities which he follows. In terms of records it easily gets out of control. Please suggest me how to change this structure to avoid timeline creation and also be abel to quickly retrieve activity for any given user. Thanks.

• Need help with Microsoft Access 07 & Reports

  - by Moe

  I'm finding it difficult to get MS reporting working to what I'd like to show. What I'm trying to do is: a) In my database store a URL file (HTTP external file), that is a .jpeg. I'd like to use that URL to call the image on the report sheet. I have tried to use 'Control source' on the data panel, but with no success. Any way I can get Dynamic Images to show up on each database. Also, I have a couple of Relational Databases. One Defines Values: For Example: DefinePets('petID','Name of Pet') The other one links the Main DB with the 'DefinePets' database. Eg: connect('petID','mainID','extraFeild') I'd like my report to Go into the "connect" Table, where the the currently viewed Record Value = mainID, then find petID and return Name of Pet. There is a many to many link between definePets and the main Table. (Therefore connect is joining them up) Or is that too much to ask from a simple package like Access?

• Will my self-taught code be fine, or should I take it to the professional level?

  - by G1i1ch

  Lately I've been getting professional work, hanging out with other programmers, and making friends in the industry. The only thing is I'm 100% self-taught. It's caused my style to extremely deviate from the style of those that are properly trained. It's the techniques and organization of my code that's different. It's a mixture of several things I do. I tend to blend several programming paradigms together. Like Functional and OO. I lean to the Functional side more than OO, but I see the use of OO when something would make more sense as an abstract entity. Like a game object. Next I also go the simple route when doing something. When in contrast, it seems like sometimes the code I see from professional programmers is complicated for the sake of it! I use lots of closures. And lastly, I'm not the best commenter. I find it easier just to read through my code than reading the comment. And most cases I just end up reading the code even if there are comments. Plus I've been told that, because of how simply I write my code, it's very easy to read it. I hear professionally trained programmers go on and on about things like unit tests. Something I've never used before so I haven't even the faintest idea of what they are or how they work. Lots and lots of underscores "_", which aren't really my taste. Most of the techniques I use are straight from me, or a few books I've read. Don't know anything about MVC, I've heard a lot about it though with things like backbone.js. I think it's a way to organize an application. It just confuses me though because by now I've made my own organizational structures. It's a bit of a pain. I can't use template applications at all when learning something new like with Ubuntu's Quickly. I have trouble understanding code that I can tell is from someone trained. Complete OO programming really leaves a bad taste in my mouth, yet that seems to be what EVERYONE else is strictly using. It's left me not that confident in the look of my code, or wondering whether I'll cause sparks when joining a company or maybe contributing to open source projects. In fact I'm rather scared of the fact that people will eventually be checking out my code. Is this just something normal any programmer goes through or should I really look to change up my techniques?

• What database is easy to maintain and manage in a cluster?

  - by Sanoj

  I'm looking for a database (DBMS) that is easy to scale out. I would like to have high availability so I need a multi-master cluster, where the data is replicated to two or more physical computers. I would also like to be able to start with one node (no replication), and then scale out to more nodes as needed without a reinstallation or downtime. I would like to have a DBMS that are easy to maintain and manage. It should be easy to add nodes, remove nodes, take live backup and monitor the use of resources. It doesn't have to be a relational database system, so a NoSQL is okey. And I would like to have a free version so I can test it in small scale and compare it with alternatives. What alternatives do I have?

• A tale from a Stalker

  - by Peter Larsson

  Today I thought I should write something about a stalker I've got. Don't get me wrong, I have way more fans than stalkers, but this stalker is particular persistent towards me. It all started when I wrote about Relational Division with Sets late last year(http://weblogs.sqlteam.com/peterl/archive/2010/07/02/Proper-Relational-Division-With-Sets.aspx) and no matter what he tried, he didn't get a better performing query than me. But this I didn't click until later into this conversation. He must have saved himself for 9 months before posting to me again. Well... Some days ago I get an email from someone I thought i didn't know. Here is his first email Hi, I want a proper solution for achievement the result. The solution must be standard query, means no using as any native code like TOP clause, also the query should run in SQL Server 2000 (no CTE use). We have a table with consecutive keys (nbr) that is not exact sequence. We need bringing all values related with nearest key in the current key row.

And here is where the conversation derailed. First I got this response back Now my solutions: --My 1st Slt SELECT T2.*, T1.*, T3.*   FROM Nums AS T1        LEFT JOIN Nums AS T2          ON T2.nbr = (SELECT MAX(nbr)                         FROM Nums                        WHERE nbr < T1.nbr)        LEFT JOIN Nums AS T3          ON T3.nbr = (SELECT MIN(nbr)                         FROM Nums                        WHERE nbr > T1.nbr); --My 2nd Slt SELECT MAX(CASE WHEN N1.nbr > N2.nbr THEN N2.nbr ELSE NULL END) AS pre_nbr,        (SELECT val FROM Nums WHERE nbr = MAX(CASE WHEN N1.nbr > N2.nbr THEN N2.nbr ELSE NULL END)) AS pre_val,        N1.nbr AS cur_nbr, N1.val AS cur_val,        MIN(CASE WHEN N1.nbr < N2.nbr THEN N2.nbr ELSE NULL END) AS nxt_nbr,        (SELECT val FROM Nums WHERE nbr = MIN(CASE WHEN N1.nbr < N2.nbr THEN N2.nbr ELSE NULL END)) AS nxt_val   FROM Nums AS N1,        Nums AS N2  GROUP BY N1.nbr, N1.val;   /* My 1st Slt Table 'Nums'.

Scan count 0, logical reads 7 Table 'Nums'. Scan count 1, logical reads 2 Table '#Temp'. Scan count 3, logical reads 16 */  To this, I emailed him back asking for a scalability test What if you try with a Nums table with 100,000 rows? His response to that started to get nasty.  I have to say Peso 2 is not acceptable. As I said before the solution must be standard, ORDER BY is not part of standard SELECT. Try this without ORDER BY:  Truncate Table Nums INSERT INTO Nums (nbr, val) VALUES (1, 0),(9,4), (5, 7)  So now we have new rules. No ORDER BY because it's not standard SQL! Of course I asked him  Why do you have that idea? ORDER BY is not standard? To this, his replies went stranger and stranger Standard Select = Set-based (no any cursor) It’s free to know, just refer to Advanced SQL Programming by Celko or mail to him if you accept comments from him. What the stalker probably doesn't know, is that I and Mr Celko occasionally are involved in some conversation and thus we exchange emails. I don't know if this reference to Mr Celko was made to intimidate me either. So I answered him, still polite, this What do you mean? The SELECT itself has a ”cursor under the hood”. Now the stalker gets rude  But however I mean the solution must no containing any order by, top... No problem, I do not like Peso 2, it’s very non-intelligent and elementary. Yes, Peso 2 is elementary but most performing queries are... And now is the time where I started to feel the stalker really wanted to achieve something else, so I wrote to him So what is your goal? Have a query that performs well, or a query that is super-portable? My Peso 2 outperforms any of your code with a factor of 100 when using more than 100,000 rows. While I awaited his answer, I posted him this query Ok, here is another one -- Peso 3 SELECT             MAX(CASE WHEN d = 1 THEN nbr ELSE NULL END) AS pre_nbr,                    MAX(CASE WHEN d = 1 THEN val ELSE NULL END) AS pre_val,                    MAX(CASE WHEN d = 0 THEN nbr ELSE NULL END) AS nbr,                    MAX(CASE WHEN d = 0 THEN val ELSE NULL END) AS val,                    MAX(CASE WHEN d = -1 THEN nbr ELSE NULL END) AS nxt_nbr,                    MAX(CASE WHEN d = -1 THEN val ELSE NULL END) AS nxt_val FROM               (                              SELECT    nbr,                                        val,                                        ROW_NUMBER() OVER (ORDER BY nbr) AS SeqID                              FROM      dbo.Nums                    ) AS s CROSS JOIN         (                              VALUES    (-1),                                        (0),                                        (1)                    ) AS x(d) GROUP BY           SeqID + x.d HAVING             COUNT(*) > 1 And here is the stats Table 'Nums'. Scan count 1, logical reads 2, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. It beats the hell out of your queries…. Now I finally got a response from my stalker and now I also clicked who he was. This is his reponse Why you post my original method with a bit change under you name? I do not like it. See: http://www.sqlservercentral.com/Forums/Topic468501-362-14.aspx ;WITH C AS ( SELECT seq_nbr, k,        DENSE_RANK() OVER(ORDER BY seq_nbr ASC) + k AS grp_fct   FROM [Sample]         CROSS JOIN         (VALUES (-1), (0), (1)         ) AS D(k) ) SELECT MIN(seq_nbr) AS pre_value,        MAX(CASE WHEN k = 0 THEN seq_nbr END) AS current_value,        MAX(seq_nbr) AS next_value   FROM C GROUP BY grp_fct HAVING min(seq_nbr) < max(seq_nbr); These posts: Posted Tuesday, April 12, 2011 10:04 AM Posted Tuesday, April 12, 2011 1:22 PM Why post a solution where will not work in SQL Server 2000? Wait a minute! His own solution is using both a CTE and a ranking function so his query will not work on SQL Server 2000! Bummer... The reference to "Me not like" are my exact words in a previous topic on SQLTeam.com and when I remembered the phrasing, I also knew who he was. See this topic http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=159262 where he writes a query and posts it under my name, as if I wrote it. So I answered him this (less polite). Like I keep track of all topics in the whole world… J So you think you are the only one coming up with this idea? Besides, “M S solution” doesn’t work.   This is the result I get pre_value        current_value                             next_value 1                           1                           5 1                           5                           9 5                           9                           9   And I did nothing like you did here, where you posted a solution which you “thought” I should write http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=159262 So why are you yourself using ranking function when this was not allowed per your original email, and no cte? You use CTE in your link above, which do not work in SQL Server 2000. All this makes no sense to me, other than you are trying your best to once in a lifetime create a better performing query than me? After a few hours I get this email back. I don't fully understand it, but it's probably a language barrier. >>Like I keep track of all topics in the whole world… J So you think you are the only one coming up with this idea?<< You right, but do not think you are the first creator of this.   >>Besides, “M S Solution” doesn’t work. This is the result I get <<   Why you get so unimportant mistake? See this post to correct it: Posted 4/12/2011 8:22:23 PM >> So why are you yourself using ranking function when this was not allowed per your original email, and no cte? You use CTE in your link above, which do not work in SQL Server 2000. <<  Again, why you get some unimportant incompatibility? You offer that solution for current goals not me  >> All this makes no sense to me, other than you are trying your best to once in a lifetime create a better performing query than me? <<  No, I only wanted to know who you will solve it. Now I know you do not have a special solution. No problem. No problem for me either. So I just answered him I am not the first, and you are not the first to come up with this idea. So what is your problem? I am pretty sure other people have come up with the same idea before us. I used this technique all the way back to 2007, see http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=93911 Let's see if he returns...  He did! >> So what is your problem? << Nothing Thanks for all replies; maybe we have some competitions in future, maybe. Also I like you but you do not attend it. Your behavior with me is not friendly. Not any meeting… Regards //Peso

• Using XML as data storage

  - by Kian Mayne

  I was thinking about the XML format and the following quote: “XML is not a database. It was never meant to be a database. It is never going to be a database. Relational databases are proven technology with more than 20 years of implementation experience. They are solid, stable, useful products. They are not going away. XML is a very useful technology for moving data between different databases or between databases and other programs. However, it is not itself a database. Don't use it like one.“ -Effective XML: 50 Specific Ways to Improve Your XML by Elliotte Rusty Harold (page 230, Part 4, Item 41, 2nd paragraph) This seems to really stress that XML should not be used for data storage and should only be used for program to program interoperability. Personally, I disagree and .NET's app.config file that's used to store a program's settings is an example of data storage in an XML file. However for databases rather than configurations etc XML should not be used. To develop my point, I will use two examples: A) Data about customers with fields that are all on one level i.e. there are a number of fields all relating to one customer with no children B) Data about configuration of an application where nested fields and properties make a lot of sense So my question is, Is this still a valid statement and is it now acceptable to store data using XML? EDIT: I've sent an email to the author of that quote to ask for his input/extra context.

• JQuery / JSON + .Net Service Layer - to WCF or Not to WCF?

  - by hanzolo

  I Recently had a discussion with a colleague of mine about the pros / cons of WCF. He mentioned about how much code is generated to support WCF, and also the overhead required. It was mentioned that a simple jQuery /Ajax post to a .aspx page (or a handler for that matter) that returns JSON would work more efficiently and takes much less code to implement. I am also aware of the new WCF Web API and feel that technology may solve the "bloated"-ness required in attaining a proxy etc... by just outputting JSON. So when developing a relational DB (MSSQL) storage model, with a fairly complex Business Layer (C#) and Data Access Layer (EntityFW).. what's a good technology for creating a "service layer" which will spit out View Models represented in JSON, with a CQRS(Command Query..) approach in mind.. The app would use the service layer to support it's required UI, as well as provide an available subset of services (outputting JSON data) for service subscribers.. In other words an admin panel to support the admin UI, and service endpoints that return JSON to access the configurations made from the administration UI. What are some potential technologies to use as the transport / communication layer. I'd like to use a pure RESTful approach, but am not against doing some URL rewriting with IIS. Obviously some of the available technologies are: WCF WCF Web API (should this even be separate?) Straight request / response (query string to .aspx / handler) Would using MVC .Net solve this entire problem? maybe their single page app approach? any suggestions / feedback from developing this type of application? Thanks,

• Choosing between PHP and Java

  - by user996459

  I've recently started University, studying Computing and IT. My Uni focuses on Java. My study will consist of mathematics, 'boring' IT related stuff and several Java units such as: -Software development with Java, -Object-oriented Java programming, -Relational databases: theory and practice (using Java), -Developing concurrent distributed systems (using Java), -Software engineering with objects (using Java). I'm trying to determine whenever I should focus on Java and self study it in my free time so that I can actually learn and become a competent Java programmer by the time I graduate, or, only do enough Java to get the degree but in my free time self study PHP and related web technologies. Job market in my area appears to be balanced for the two, salary and availability wise. Regardless of which patch I'd take getting a job should not be a problem however Java does seem to pay almost insignificantly more. In terms of my interest and career expectations, I don't have anything specific planned. I very much enjoy writing code but I don't really care what kind. So far I equally enjoyed writing C, AutoIT, vb.net, PHP and even Java. Basically, I'm happy as long as I get to type in code (be it low level programming or web back-end scripting). So the question really is, would my Uni and their Java focus profit me should I choose PHP? Or should I buy what my university is selling and stick to Java like a fly sticks to poop...? Apologies for cryptic writing, still learning English

• Internship in License Contract Management

  - by cristian.condurache(at)oracle.com

  Hi Everyone, My name is Luca. I am an intern in the License Contract Management team in Italy. I have studied Economics and Business in Pescara and finished my Master’s Degree in July 2009. After a short work experience near my home town I decided to look for a job in an International Company. I got in touch with Oracle in January 2010. I had a telephone interview and then a face-to-face interview. On a cold and grey morning, I arrived in Milan....my first impression was fantastic....a big modern building with wide TVs everywhere. I was a little nervous but very excited. I understood this could be a great opportunity... The interview went well and I started to work in March. After a training period I was quickly involved in the closing of the last quarter of the fiscal year - of which May is the last month at Oracle. Working as a License Contract Manager is a real challenge for a fresh graduate. It involves thoroughly understanding the Oracle Policies and Practices with regards to License Contracts. In my experience, especially in May, I learnt to work under high pressure, within time constrains, and to keep up with constant changes. In this period I also had the opportunity to be involved in different negotiations, being directly in contact with the customers. This helped me to develop my relational skills during complex transactions. Looking back at the nine months at Oracle I can say I have a better understanding of the IT world. It is a complex environment that changes continously, offering new challenges to learn from everytime. If you have any questions related to this article feel free to contact [email protected]. You can find our job opportunities via http://campus.oracle.com. Technorati Tags: License Contract Management,oppotunity,Oracle Policies,internship

• ODSI + weblogic = JDBC problem

  - by Giuseppe Di Federico

  I'm currently developing a web service using ODSI through Oracle Workshop for WebLogic (ex AquaLogic). I created a datasource on weblogic using the driver "Oracle thin driver 10g", the test succeed on WebLogic. (My Database is Oracle 10 10.2.0.1.0) The problem occours when I try to create the Phisical Data Service in the Oracle Workshop. I choose the following options: Data source type = Relational Data source = [THE CORRECT NAME OF THE SOURCE SET ON WEBLOGIC] Database type = ??? Aqualogic, doesn't allow me to select the database type. I guess is a problem related to the driver set on weblogic... but I ain't sure.Does someone know the nature of my problem ? Tnx

• Best Persistence choice for J2EE-App with frequently changing Data Model

  - by Ben-G

  Whenever I develop a J2EE-Application, I at some point decide to switch from my dummy Persistence (Simply Using Lists and other Data Structures) to some Sort of Database Persistence. Mostly when I hope the Data Model is more or less complete. From this point on, changes to the data model become exhausting, but unluckily they occur rather often. I've used different Object-Relational-Mappers (iBatis, Hibernate) for my projects. They definitely reduce the pain coming with Data Model changes, but they anyway let me adjust code/configuration at 3 or 4 places for every single change. To me, that's cumbersome and error prone. I made a better experience with DB4O, which simply persists Java Objects as they are, but I believe it's performance does not scale for huge applications. Is there anyway to maintain performance while letting out all the ugly configuration work? I'm seeking a performant framework which really hides persistence from my code. Wish for thinking? Or am I missing out THE technology? Hope you can help.

• Key ATG architecture principles

  - by Glen Borkowski

  Overview The purpose of this article is to describe some of the important foundational concepts of ATG.  This is not intended to cover all areas of the ATG platform, just the most important subset - the ones that allow ATG to be extremely flexible, configurable, high performance, etc.  For more information on these topics, please see the online product manuals. Modules The first concept is called the 'ATG Module'.  Simply put, you can think of modules as the building blocks for ATG applications.  The ATG development team builds the out of the box product using modules (these are the 'out of the box' modules).  Then, when a customer is implementing their site, they build their own modules that sit 'on top' of the out of the box ATG modules.  Modules can be very simple - containing minimal definition, and perhaps a small amount of configuration.  Alternatively, a module can be rather complex - containing custom logic, database schema definitions, configuration, one or more web applications, etc.  Modules generally will have dependencies on other modules (the modules beneath it).  For example, the Commerce Reference Store module (CRS) requires the DCS (out of the box commerce) module. Modules have a ton of value because they provide a way to decouple a customers implementation from the out of the box ATG modules.  This allows for a much easier job when it comes time to upgrade the ATG platform.  Modules are also a very useful way to group functionality into a single package which can be leveraged across multiple ATG applications. One very important thing to understand about modules, or more accurately, ATG as a whole, is that when you start ATG, you tell it what module(s) you want to start.  One of the first things ATG does is to look through all the modules you specified, and for each one, determine a list of modules that are also required to start (based on each modules dependencies).  Once this final, ordered list is determined, ATG continues to boot up.  One of the outputs from the ordered list of modules is that each module can contain it's own classes and configuration.  During boot, the ordered list of modules drives the unified classpath and configpath.  This is what determines which classes override others, and which configuration overrides other configuration.  Think of it as a layered approach. The structure of a module is well defined.  It simply looks like a folder in a filesystem that has certain other folders and files within it.  Here is a list of items that can appear in a module: MyModule: META-INF - this is required, along with a file called MANIFEST.MF which describes certain properties of the module.  One important property is what other modules this module depends on. config - this is typically present in most modules.  It defines a tree structure (folders containing properties files, XML, etc) that maps to ATG components (these are described below). lib - this contains the classes (typically in jarred format) for any code defined in this module j2ee - this is where any web-apps would be stored. src - in case you want to include the source code for this module, it's standard practice to put it here sql - if your module requires any additions to the database schema, you should place that schema here Here's a screenshots of a module: Modules can also contain sub-modules.  A dot-notation is used when referring to these sub-modules (i.e. MyModule.Versioned, where Versioned is a sub-module of MyModule). Finally, it is important to completely understand how modules work if you are going to be able to leverage them effectively.  There are many different ways to design modules you want to create, some approaches are better than others, especially if you plan to share functionality between multiple different ATG applications. Components A component in ATG can be thought of as a single item that performs a certain set of related tasks.  An example could be a ProductViews component - used to store information about what products the current customer has viewed.  Components have properties (also called attributes).  The ProductViews component could have properties like lastProductViewed (stores the ID of the last product viewed) or productViewList (stores the ID's of products viewed in order of their being viewed).  The previous examples of component properties would typically also offer get and set methods used to retrieve and store the property values.  Components typically will also offer other types of useful methods aside from get and set.  In the ProductViewed component, we might want to offer a hasViewed method which will tell you if the customer has viewed a certain product or not. Components are organized in a tree like hierarchy called 'nucleus'.  Nucleus is used to locate and instantiate ATG Components.  So, when you create a new ATG component, it will be able to be found 'within' nucleus.  Nucleus allows ATG components to reference one another - this is how components are strung together to perform meaningful work.  It's also a mechanism to prevent redundant configuration - define it once and refer to it from everywhere. Here is a screenshot of a component in nucleus:  Components can be extremely simple (i.e. a single property with a get method), or can be rather complex offering many properties and methods.  To be an ATG component, a few things are required: a class - you can reference an existing out of the box class or you could write your own a properties file - this is used to define your component the above items must be located 'within' nucleus by placing them in the correct spot in your module's config folder Within the properties file, you will need to point to the class you want to use: $class=com.mycompany.myclass You may also want to define the scope of the class (request, session, or global): $scope=session In summary, ATG Components live in nucleus, generally have links to other components, and provide some meaningful type of work.  You can configure components as well as extend their functionality by writing code.

Data Anywhere Architecture) is the mechanism that ATG uses to access data primarily stored in relational databases, but also LDAP or other backend systems.  ATG applications are required to be very high performance, and data access is critical in that if not handled properly, it could create a bottleneck.  ATG's repository functionality has been around for a long time - it's proven to be extremely scalable.  Developers new to ATG need to understand how repositories work as this is a critical aspect of the ATG architecture.   Repositories essentially map relational tables to objects in ATG, as well as handle caching.  ATG defines many repositories out of the box (i.e. user profile, catalog, orders, etc), and this is comprised of both the underlying database schema along with the associated repository definition files (XML).  It is fully expected that implementations will extend / change the out of the box repository definitions, so there is a prescribed approach to doing this.  The first thing to be sure of is to encapsulate your repository definition additions / changes within your own module (as described above).  The other important best practice is to never modify the out of the box schema - in other words, don't add columns to existing ATG tables, just create your own new tables.  These will help ensure you can easily upgrade your application at a later date. xml-combination As mentioned earlier, when you start ATG, the order of the modules will determine the final configpath.  Files within this configpath are 'layered' such that modules on top can override configuration of modules below it.  This is the same concept for repository definition files.  If you want to add a few properties to the out of the box user profile, you simply need to create an XML file containing only your additions, and place it in the correct location in your module.  At boot time, your definition will be combined (hence the term xml-combination) with the lower, out of the box modules, with the result being a user profile that contains everything (out of the box, plus your additions).  Aside from just adding properties, there are also ways to remove and change properties. types of properties Aside from the normal 'database backed' properties, there are a few other interesting types: transient properties - these are properties that are in memory, but not backed by any database column.  These are useful for temporary storage. java-backed properties - by nature, these are transient, but in addition, when you access this property (by called the get method) instead of looking up a piece of data, it performs some logic and returns the results.  'Age' is a good example - if you're storing a birth date on the profile, but your business rules are defined in terms of someones age, you could create a simple java-backed property to look at the birth date and compare it to the current date, and return the persons age. derived properties - this is what allows for inheritance within the repository structure.  You could define a property at the category level, and have the product inherit it's value as well as override it.  This is useful for setting defaults, with the ability to override. caching There are a number of different caching modes which are useful at different times depending on the nature of the data being cached.  For example, the simple cache mode is useful for things like user profiles.  This is because the user profile will typically only be used on a single instance of ATG at one time.  Simple cache mode is also useful for read-only types of data such as the product catalog.  Locked cache mode is useful when you need to ensure that only one ATG instance writes to a particular item at a time - an example would be a customers order.  There are many options in terms of configuring caching which are outside the scope of this article - please refer to the product manuals for more details. Other important concepts - out of scope for this article There are a whole host of concepts that are very important pieces to the ATG platform, but are out of scope for this article.  Here's a brief description of some of them: formhandlers - these are ATG components that handle form submissions by users. pipelines - these are configurable chains of logic that are used for things like handling a request (request pipeline) or checking out an order. special kinds of repositories (versioned, files, secure, ...) - there are a couple different types of repositories that are used in various situations.  See the manuals for more information. web development - JSP/ DSP tag library - ATG provides a traditional approach to developing web applications by providing a tag library called the DSP library.  This library is used throughout your JSP pages to interact with all the ATG components. messaging - a message sub-system used as another way for components to interact. personalization - ability for business users to define a personalized user experience for customers.  See the other blog posts related to personalization.

• SQL Server 2008 R2: These are a Few of My Favorite Things

  - by smisner

  This month's T-SQL Tuesday is hosted by Jorge Segarra (blog | twitter) who decided that we should write about our favorite new feature in SQL Server 2008 R2. The majority of my published works concentrates on Reporting Services, so the obious answer for me is about favorite new features is...Reporting Services. I can't pick just one thing in Reporting Services, so instead I thought I'd compile a list of my posts of the new features in Reporting Services 2008 R2: Map Wizard for spatial data (The World is But a Stage) Pagination features (I've Got Your Page Number) Lookup functions (Look Up, Look Down, Look All Around - Part I, Part II, Part III) Test Connection button (Testing, Testing 1-2-3) Conditional formatting based on format, i.e. RenderFormat (As You Like It) And I wrote an overview of the business intelligence features in SQL Server 2008 R2 for Microsoft Press in the free e-book, Introducing Microsoft SQL Server 2008 R2, if you're curious about what else is new in both the BI platform as well as the relational engine.

• django & postgres linux hosting (with SSH access) recommendations

  - by Justin Grant

  We're looking for a good place to host our custom Django app (a fork of OSQA) and its postgresql backend. Requirements include: Linux Python 2.6 or (ideally) Python 2.7 Django 1.2 Postgres 8.4 or later DB backup/restore handled by the hoster, not us OS & dev-platform-stack patching/maintenance handled by the hoster, not us SSH access (so we can pull source code from GitHub, so we can install python eggs, etc.) ability to set up cron jobs (e.g. to send out dail email updates) ability to send up to 10K emails/day good performance (not ganged up with a zillion other sites on one CPU, not starved for RAM) FTP or SCP access to web logs dedicated public IP SSL support Costs under $1000/month for a relatively small site (<5M pageviews/month) Good customer service We already have a prototype site running on EC2 on top of a Bitnami DjangoStack. The problem is that we have to patch the OS, patch postgres, etc. We'd really prefer a platform-as-a-service (PaaS) offering, like Heroku offers for Rails apps, where all we need to worry about is deploying our code instead of worrying about system software patching and maintenance. Google App Engine is closest to what we're looking for, but they don't offer relational DB access (not yet at least). Anyone have a recommendation?

• Why isn't DSM for unstructured memory done today?

  - by sinned

  Ages ago, Djikstra invented IPC through mutexes which then somehow led to shared memory (SHM) in multics (which afaik had the necessary mmap first). Then computer networks came up and DSM (distributed SHM) was invented for IPC between computers. So DSM is basically a not prestructured memory region (like a SHM) that magically get's synchronized between computers without the applications programmer taking action. Implementations include Treadmarks (inofficially dead now) and CRL. But then someone thought this is not the right way to do it and invented Linda & tuplespaces. Current implementations include JavaSpaces and GigaSpaces. Here, you have to structure your data into tuples. Other ways to achieve similar effects may be the use of a relational database or a key-value-store like RIAK. Although someone might argue, I don't consider them as DSM since there is no coherent memory region where you can put data structures in as you like but have to structure your data which can be hard if it is continuous and administration like locking can not be done for hard coded parts (=tuples, ...). Why is there no DSM implementation today or am I just unable to find one?
