• 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.

• Car Modelling for race game

  - by Mert Toka

  I am taking Computer Graphics course this semester and we have a video game competition. I am making racing game with simulated dynamics. Our professor told us that we don't have to do much of a modelling but since we haven't started the gaming part and since I have free time I want to model the car. My question is firstly which software do you recommend to design game components? I know Maya right now. Secondly, if I design the car or any other part, what should its polygon count in order to run game smoothly? I can design pretty much everything but I assume that it is hard to design low-poly models.

• Isn't MVC anti OOP?

  - by m3th0dman

  The main idea behind OOP is to unify data and behavior in a single entity - the object. In procedural programming there is data and separately algorithms modifying the data. In the Model-View-Controller pattern the data and the logic/algorithms are placed in distinct entities, the model and the controller respectively. In an equivalent OOP approach shouldn't the model and the controller be placed in the same logical entity?

• How do you coordinate with interaction designers during implementation?

  - by Alex Feinman

  Programmers are largely responsible for helping move a product from design to implementation. This process is always full of snags: implementation details rear their ugly head and make parts of the design infeasible user feedback on early prototypes leads to changes in the design new technologies alter the field of what is possible, bringing back designs previously thought impossible priorities shift, schedules change, and requirements wander How do you keep design and implementation in contact during the implementation? What processes do you use? Tools? Artifacts? Guidelines? Communication strategies?

• Tips about how to spread Object Oriented practices

  - by Augusto

  I work for a medium company that has around 250 developers. Unfortunately, lots of them are stuck in a procedural way of thinking and some teams constantly deliver big Transactional Script applications, when in fact the application contains rich logic. They also fail to manage the design dependencies, and end up with services which depend on another large number of services (a clean example of Big Ball of Mud). My question is: Can you suggest how to spread this type of knowledge? I know that the surface of the problem is that these applications have a poor architecture and design. Another issue is that there are some developers who are against writing any kind of test. A few things I'm doing to change this (but I'm either failing or the change is too small are) Running presentations about design principles (SOLID, clean code, etc). Workshops about TDD and BDD. Coaching teams (this includes using sonar, findbugs, jdepend and other tools). IDE & Refactoring talks. A few things I'm thinking to do in the future (but I'm concern that they might not be good) Form a team of OO evangelists, who disseminate an OO way of thinking in differet teams (these people would need to change teams every few months). Running design review sessions, to criticise the design and suggest improvements (even if the improvements are not done because of time constraints, I think this might be useful) . Something I found with the teams I coach, is that as soon as I leave them, they revert back to the old practices. I know I don't spend a lot of time with them, usually just one month. So whatever I'm doing, it doesn't stick. I'm sorry this question is spattered with frustration, but the alterative to write this was to hit my head on the wall until I pass out.

• How many tiers should my models have in a DB driven web app?

  - by Hanno Fietz

  In my experience, the "Model" in MVC is often not really a single layer. I would regularly have "backend" models and "frontend" models, where the backend ones would have properties that I want to hide from the UI code, and the frontend ones have derived or composite properties which are more meaningful in the context of the UI. Recently, I have started to introduce a third layer in between when database normalization created tables that did not really match the conceptual domain objects anymore. In those projects I have model classes that are equivalent with the DB structure, these become components of objects that represent the domain model, and finally these are filtered and amended for displaying information to the user. Are there patterns or guidelines for how, when and why to organize the data model across application layers?

• Does MVC apply only to web

  - by Deeptechtons

  It is almost and instantaneous whenever I talk to developers about Model View Controller (MVC) they say you make a request to a url the server builds a entity (MODEL) and provides you with visual representation of that model. So does this mean MVC is only for the web or have I been meeting people who are just developers who employ MVC for writing web applications? Are there usages for MVC on desktop style applications? I for one am new to paradigm and would like to know of any super-set to MVC

• What is the best approach for creating a Common Information Model?

  - by Kaiser Advisor

  Hi, I would like to know the best approach to create a Common Information Model. Just to be clear, I've also heard it referred to as a canonical information model, semantic information model, and master data model - As far as I can tell, they are all referring to the same concept. I've heard in the past that a combined "top-down" and "bottom-up" approach is best. This has the advantage of incorporating "Ivory tower" architects and developers - The work will meet somewhere in the middle and usually be both logical and practical. However, this involves bringing in a lot of people with different skill sets. I've also seen a couple of references to the Distributed Management Task Force, but I can't glean much on best practices in terms of CIM development. This is something I'm quite interested in getting some feedback on since having a strong CIM is a prerequisite to SOA. Thanks for your help! KA Update I've heard another strategy goes along with overall SOA implementation: Get the business involved, and seek executive sponsorship. This would be part of the "Top-down" effort.

• Asp.Net MVC - Binding of parameter to model value!

  - by Pino

  This seems like the model binding is causing me issues. Essentially I have a model called ProductOption and for the purpose of this question it has 2 fields ID (Int) PK ProductID (Int) FK I have a standard route set-up context.MapRoute( "Product_default", "Product/{controller}/{action}/{id}", new { controller = "Product", action = "Index", id = UrlParameter.Optional } ); and if the user wants to add an option the URL is, /Product/Options/Add/1 in the above URL 1 is the ProductID, I have the following code to return a blank model the the view, [HttpGet] public ActionResult Add(int id) { return View("Manage", new ProductOptionModel() { ProductID = id }); } Now in my view I keep a hidden field <%= Html.HiddenFor(x=>x.ID) %> This is used to determine (on submit) if we are editing or adding a new option. However the Model binder in .net seems to replace .ID (Which was 0 when leaving the above get actionresult) with 1 (or the value of the id parameter in the URL) How can I stop or work around this? ViewModel public class ProductExtraModel { //Database public int ID { get; set; } public string Name { get; set; } public int ProductID { get; set; } public ProductModel Product { get; set; } }

• What are the benefits and risks of moving to a Model Driven Architecture approach?

  - by Tone

  I work for a company with about 350 employees and we are in the process of growing. Our current codebase is not structured very well and we are looking both at how to improve it immediately (by organizing objects into namespaces, separating concerns, etc.) and moving to a model driven architecture approach, where we model and design everything first with uml, then generate code from that model. We have been looking heavily at Sparx Systems Enterprise Architect (EA) (which is UML 2.0 capable) and we are also considering the tools in VS 2010. I know there are other tools out there (Rational XDE being one) but I really do not think we can spend $1500+ per license at this point. I'm not looking for answers on which tool is better than another but more for experiences moving from a cowboy coding environment (that is, little planning and design, just jump in and start coding) to a model driven architecture. Looking back was it helpful to your organization? What are the pain points? What are the risks? What are the benefits?

• Does the Java Memory Model (JSR-133) imply that entering a monitor flushes the CPU data cache(s)?

  - by Durandal

  There is something that bugs me with the Java memory model (if i even understand everything correctly). If there are two threads A and B, there are no guarantees that B will ever see a value written by A, unless both A and B synchronize on the same monitor. For any system architecture that guarantees cache coherency between threads, there is no problem. But if the architecture does not support cache coherency in hardware, this essentially means that whenever a thread enters a monitor, all memory changes made before must be commited to main memory, and the cache must be invalidated. And it needs to be the entire data cache, not just a few lines, since the monitor has no information which variables in memory it guards. But that would surely impact performance of any application that needs to synchronize frequently (especially things like job queues with short running jobs). So can Java work reasonably well on architectures without hardware cache-coherency? If not, why doesn't the memory model make stronger guarantees about visibility? Wouldn't it be more efficient if the language would require information what is guarded by a monitor? As i see it the memory model gives us the worst of both worlds, the absolute need to synchronize, even if cache coherency is guaranteed in hardware, and on the other hand bad performance on incoherent architectures (full cache flushes). So shouldn't it be more strict (require information what is guarded by a monitor) or more lose and restrict potential platforms to cache-coherent architectures? As it is now, it doesn't make too much sense to me. Can somebody clear up why this specific memory model was choosen? EDIT: My use of strict and lose was a bad choice in retrospect. I used "strict" for the case where less guarantees are made and "lose" for the opposite. To avoid confusion, its probably better to speak in terms of stronger or weaker guarantees.

• OSI Model

  - by kaleidoscope

  The Open System Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model. A layer is a collection of conceptually similar functions that provide services to the layer above it and receives service from the layer below it. Description of OSI layers: Layer 1: Physical Layer ·         Defines the electrical and physical specifications for devices. In particular, it defines the relationship between a device and a physical medium. ·         Establishment and termination of a connection to a communications medium. ·         Participation in the process whereby the communication resources are effectively shared among multiple users. ·         Modulation or conversion between the representation of digital data in user equipment and the corresponding signals transmitted over a communications channel. Layer 2: Data Link Layer ·         Provides the functional and procedural means to transfer data between network entities. ·         Detect and possibly correct errors that may occur in the Physical Layer. The error check is performed using Frame Check Sequence (FCS). ·         Addresses is then sought to see if it needs to process the rest of the frame itself or whether to pass it on to another host. ·         The Layer is divided into two sub layers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. ·         MAC sub layer controls how a computer on the network gains access to the data and permission to transmit it. ·         LLC layer controls frame synchronization, flow control and error checking.   Layer 3: Network Layer ·         Provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks. ·         Performs network routing functions, and might also perform fragmentation and reassembly, and report delivery errors. ·         Network Layer Routers operate at this layer—sending data throughout the extended network and making the Internet possible.   Layer 4: Transport Layer ·         Provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. ·         Controls the reliability of a given link through flow control, segmentation/de-segmentation, and error control. ·         Transport Layer can keep track of the segments and retransmit those that fail. Layer 5: Session Layer ·         Controls the dialogues (connections) between computers. ·         Establishes, manages and terminates the connections between the local and remote application. ·         Provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. ·         Implemented explicitly in application environments that use remote procedure calls. Layer 6: Presentation Layer ·         Establishes a context between Application Layer entities, in which the higher-layer entities can use different syntax and semantics, as long as the presentation service understands both and the mapping between them. The presentation service data units are then encapsulated into Session Protocol data units, and moved down the stack. ·         Provides independence from differences in data representation (e.g., encryption) by translating from application to network format, and vice versa. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. It is sometimes called the syntax layer. Layer 7: Application Layer ·         This layer interacts with software applications that implement a communicating component. ·         Identifies communication partners, determines resource availability, and synchronizes communication. o       When identifying communication partners, the application layer determines the identity and availability of communication partners for an application with data to transmit. o       When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists. o       In synchronizing communication, all communication between applications requires cooperation that is managed by the application layer.

• Bancassurers Seek IT Solutions to Support Distribution Model

  - by [email protected]

  Oracle Insurance's director of marketing for EMEA, John Sinclair, attended the third annual Bancassurance Forum in Vienna last month. He reports that the outlook for bancassurance in EMEA remains positive, despite changing market conditions that have led a number of bancassurers to re-examine their business models. Vienna is at the crossroads between mature Western European markets, where bancassurance is now an established best practice, and more recently tapped Eastern European markets that offer the greatest growth potential. Attendance at the Bancassurance Forum was good, with 87 bancassurance attendees, most in very senior positions in the industry. The conference provided the chance for a lively discussion among bancassurers looking to keep abreast of the latest trends in one of Europe's most successful distribution models for insurance. Even under normal business conditions, there is a great demand for best practice sharing within the industry as there is no standard formula for success.  Each company has to chart its own course and choose the strategies for sales, products development and the structure of ownership that make sense for their business, and as soon as they get it right bancassurers need to adapt the mix to keep up with ever changing regulations, completion and economic conditions.  To optimize the overall relationship between banking and insurance for mutual benefit, a balance needs to be struck between potentially conflicting interests. The banking side of the house is looking for greater wallet share from its customers and the ability to increase profitability by bundling insurance products with higher margins - especially in light of the recent economic crisis, where margins for traditional banking products are low and completion high. The insurance side of the house seeks access to new customers through a complementary distribution channel that is efficient and cost effective. To make the relationship work, it is important that both sides of the same house forge strategic and long term relationships - irrespective of whether the underlying business model is supported by a distribution agreement, cross-ownership or other forms of capital structure. However, this third annual conference was not held under normal business conditions. The conference took place in challenging, yet interesting times. ING's forced spinoff of its insurance operations under pressure by the EU Commission and the troubling losses suffered by Allianz as a result of the Dresdner bank sale were fresh in everyone's mind. One year after markets crashed, there is now enough hindsight to better understand the implications for bancassurance and best practices that are emerging to deal with them. The loan-driven business that has been crucial to bancassurance up till now evaporated during the crisis, leaving bancassurers grappling with how to change their overall strategy from a loan-driven to a more diversified model.  Attendees came to the conference to learn what strategies were working - not only to cope with the market shift, but to take advantage of it as markets pick up. Over the course of 14 customer case studies and numerous analyst presentations, topical issues ranging from getting the business model right to the impact on capital structuring of Solvency II were debated openly. Many speakers alluded to the need to specifically design insurance products with the banking distribution channel in mind, which brings with it specific requirements such as a high degree of standardization to achieve efficiency and reduce training costs. Moreover, products must be engineered to suit end consumers who consider banks a one-stop shop. The importance of IT to the successful implementation of bancassurance strategies was a theme that surfaced regularly throughout the conference.  The cross-selling opportunity - that will ultimately determine the success or failure of any bancassurance model - can only be fully realized through a flexible IT architecture that enables banking and insurance processes to be integrated and presented to front-line staff through a common interface. However, the reality is that most bancassurers have legacy IT systems, which constrain the businesses' ability to implement new strategies to maintaining competitiveness in turbulent times. My colleague Glenn Lottering, who chaired the conference, believes that the primary opportunities for bancassurers to extract value from their IT infrastructure investments lie in distribution management, risk management with the advent of Solvency II, and achieving operational excellence. "Oracle is ideally suited to meet the needs of bancassurance," Glenn noted, "supplying market-leading software for both banking and insurance. Oracle provides adaptive systems that let customers easily integrate hybrid business processes from both worlds while leveraging existing IT infrastructure." Overall, the consensus at the conference was that the outlook for bancassurance in EMEA remains positive, despite changing market conditions that have led a number of bancassurers to re-examine their business models. John Sinclair is marketing director for Oracle Insurance in EMEA. He has more than 20 years of experience in insurance and financial services.

• InfoPath 2010 Form Design and Web Part Deployment

  - by JKenderdine

  In January I had the pleasure to speak at SharePoint Saturday Virginia Beach.  I presented a session on InfoPath 2010 forms design which included some of the basics of Forms Design, description of some of the new options with InfoPath 2010 and SharePoint 2010, and other integration possibilities.  Included below is the information presented as well as the solution to create the demo: First thing you need to understand is what the difference is between an InfoPath List form and a Form Library Form?  SharePoint List Forms:  Store data directly in a SharePoint list.  Each control (e.g. text box) in the form is bound to a column in the list. SharePoint list forms are directly connected to the list, which means that you don’t have to worry about setting up the publish and submit locations. You also do not have the option for back-end code. Form Library Forms:  Store data in XML files in a SharePoint form library.  This means they are more flexible and you can do more with them.  For example, they can be configured to save drafts and submit to different locations. However, they are more complex to work with and require more decisions to be made during configuration.  You do have the option of back-end code with these type of forms. Next steps: You need to create your File Architecture Plan.  Plan the location for the saved template – both Test and Production (This is pretty much a given, but just in case - Always make sure to have a test environment) Plan for the location of the published template Then you need to document your Form Template Design Plan.  Some questions to ask to gather your requirements: What will the form be designed to do? Will it gather user information? Will it display data from a data source? Do we need to show different views to different users? What do we base this on? How will it be implemented for the users? Browser or Client based form Site collection content type – Published through Central Admin Form Library – Published directly to form library So what are the requirements for this template?  Business Card Request Form Template Design Plan Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Show and hide fields as necessary for requirements Create multiple views – one for those submitting the form and another view for the executive assistants placing the orders. Browser based form integrated into SharePoint team site Published directly to form library The form was published through Central Administration and incorporated into the site as a content type. Utilizing the new InfoPath Web part, the form is integrated into the page and the users can complete the form directly from within that page. For now, if you are interested in the final form XSN, contact me using the Contact link above.   I will post soon with the details on how the form was created and how it integrated the requirements detailed above.

• Multitenant Design for SQL Azure: White Paper Available

  - by Herve Roggero

  Cloud computing is about scaling out all your application tiers, from web application to the database layer. In fact, the whole promise of Azure is to pay for just what you need. You need more IIS servers? No problemo... just spin another web server. You expect to double your storage needs for Azure Tables? No problemo; you are covered there too... just pay for your storage needs. But what about the database tier, SQL Azure? How do you add new databases easily, and transparently, so that your application simply uses more of SQL Azure if its needs to? Without changing a single line of code? And what if you need to scale back down? Welcome to the world of database scalability. There are many terms that describe database scalability, including data federation, multitenant designs, and even NoSQL depending on the technical solution you are implementing.  Because SQL Azure is a transactional database system, NoSQL is not really an option. However data federation and multitenant designs offer some very interesting scalability options that are worth considering. Data federation, a feature of SQL Azure that will be offered in the future, offers very interesting capabilities available natively on the SQL Azure platform. More to come in a few weeks... Multitenant designs on the other hand are design practices and technologies designed to help you reach flexible scalability options not available otherwise. The first incarnation of such a method was made available on CodePlex as an open source project (http://enzosqlshard.codeplex.com).  This project was an attempt to provide a sharding library for educational purposes.  All that sounds really cool... and really esoteric... almost a form of database "voodoo"... However after being on multiple Azure projects I am starting to see a real need. Customers want to be able to free themselves from the database tier, so that if they have 10 new customers tomorrow, all they need to do is add 2 more SQL Azure instances. It's that simple. How you achieve this, and suggested application design guidelines, are available in a white paper I just published.  The white paper offers two primary sections. The first section describes the business and technical problem at hand, and how to classify it according to specific design patterns. For example, I discuss compressed shards through schema separation. The second section offers a method for addressing the needs of a multitenant design using a new library, the big bother of the codeplex project mentioned previously (that I created earlier this year), complete with management interface and such. A Beta of this platform will be made available within weeks; as soon as the documentation will be ready.   I would like to ask you to drop me a quick email at [email protected] if you are going to download the white paper. It's not required, but it would help me get in touch with you for feedback.  You can download this white paper here:   http://www.bluesyntax.net/files/EnzoFramework.pdf . Thank you, and I am looking for feedback, thoughts and implementation opportunities.

Array ( [Receipt] => Array ( [ID] => 566 [ObjectType] => 84 [TXNName] => bbnm [TXNDate] => 03-06-2014 [BranchID] => 1 [Narration1] => 267 [Narration] => Cheque Received [ExecutiveID] => 805 [AccountType] => 104 [Account] => 68 [ReferenceNo] => [TXNCurrencyID] => 3 [ExchangeRate] => 1.00000 [ManualAdiustment] => 0 [RevisionNumber] => 1 [CompanyID] => 1 [Status] => 633 ) [ReceiptLine] => Array ( [0] => Array ( [TXNID] => 566 [LineNo] => 0 [LineType_072] => 429 [BranchID] => 1 [AccountID] => 68 [ContactID] => [Amount] => 0 [CancelAmount] => 0 [OpenAmount] => 0 [Narration] => Cheque Received [CreatedBy] => 229 [ModifiedBy] => 229 [CreatedDate] => 2014-06-03 00:00:00 [ModifiedDate] => 2014-06-03 00:00:00 [Status] => 1 [RevisionNumber] => 1 [RowState] => [tmpInstrumentDate] => ) [1] => Array ( [LineNo] => 0 [RowState] => 436 [TXNID] => 0 [BranchID] => 1 [ContactID] => [AccountID] => 68 [Narration] => Cheque Received [Amount] => 0 [RevisionNumber] => 1 [LineType_072] => 460 [CancelAmount] => 0 [OpenAmount] => 0 [Status] => 1 ) ) [OpeningBankStatement] => Array ( [ObjectType] => 131 [TXNSeries] => 1 [TXNNo] => 12345 [TXNName] => bbnm [TXNDate] => 03-06-2014 [CompanyID] => 1 [AccountID] => 68 [ExecutiveID] => 805 [Narration] => Cheque Received [ReferenceNo] => [ParentObjectType] => 84 [ParentTXNID] => 1 [CancelledBy] => 1 [CancelledDate] => 2014-02-02 [CancellationRemarks] => hfg [Status] => 1 [RevisionNumber] => 1 ) ) By any dyanamic model association or callback method it solve? suggest solution.

• JMX Based Monitoring - Part Two - JVM Monitoring

  - by Anthony Shorten

  This the second article in the series focussing on the JMX based monitoring capabilities possible with the Oracle Utilities Application Framework. In all versions of the Oracle utilities Application Framework, it is possible to use the basic JMX based monitoring available with the Java Virtual Machine to provide basic statistics ablut the JVM. In Java 5 and above, the JVM automatically allowed local monitoring of the JVM statistics from an approporiate console. When I say local I mean the monitoring tool must be executed from the same machine (and in some cases the same user that is running the JVM) to connect to the JVM directly. If you are using jconsole, for example, then you must have access to a GUI (X-Windows or Windows) to display the jconsole output. This is the easist way of monitoring without doing too much configration but is not always practical. Java offers a remote monitorig capability to allow yo to connect to a remotely executing JVM from a console (like jconsole). To use this facility additional JVM options must be added to the command line that started the JVM. Details of the additional options for the version of the Java you are running is located at the JMX information site. Typically to remotely connect to a running JVM that JVM must be configured with the following categories of options: JMX Port - The JVM must allow connections on a listening port specified on the command line Connection security - The connection to the JVM can be secured. This is recommended as JMX is not just a monitoring protocol it is a managemet protocol. It is possible to change values in a running JVM using JMX and there are NO "Are you sure?" safeguards. For a Oracle Utilities Application Framework based application there are a few guidelines when configuring and using this JMX based remote monitoring of the JVM's: Online JVM - The JVM used to run the online system is embedded within the J2EE Web Application Server. To enable JMX monitoring on this JVM you can either change the startup script that starts the Web Application Server or check whether your J2EE Web Application natively supports JVM statistics collection. Child JVM's (COBOL only) - The Child JVM's should not be monitored using this method as they are recycled regularly by the configuration and therefore statistics collected are of little value. Batch Threadpoools - Batch already has a JMX interface (which will be covered in another article). Additional monitoring can be enabled but the base supported monitoring is sufficient for most needs. If you are an Oracle Utilities Application Framework site, then you can specify the additional options for JMX Java monitoring on the OPTS paramaters supported for each component of the architecture. Just ensure the port numbers used are unique for each JVM running on any machine.

• C# Domain-Driven Design Sample Released

  - by Artur Trosin

  In the post I want to declare that NDDD Sample application(s) is released and share the work with you. You can access it here: http://code.google.com/p/ndddsample. NDDDSample from functionality perspective matches DDDSample 1.1.0 which is based Java and on joint effort by Eric Evans' company Domain Language and the Swedish software consulting company Citerus. But because NDDDSample is based on .NET technologies those two implementations could not be matched directly. However concepts, practices, values, patterns, especially DDD, are cross-language and cross-platform :). Implementation of .NET version of the application was an interesting journey because now as .NET developer I better understand the differences positive and negative between these two platforms. Even there are those differences they can be overtaken, in many cases it was not so hard to match a java libs\framework with .NET during the implementation. Here is a list of technology stack: 1. .net 3.5 - framework 2. VS.NET 2008 - IDE 3. ASP.NET MVC2.0 - for administration and tracking UI 4. WCF - communication mechanism 5. NHibernate - ORM 6. Rhino Commons - Nhibernate session management, base classes for in memory unit tests 7. SqlLite - database 8. Windsor - inversion of control container 9. Windsor WCF facility - for better integration with NHibernate 10. MvcContrib - and in particular its Castle WindsorControllerFactory in order to enable IoC for controllers 11. WPF - for incident logging application 12. Moq - mocking lib used for unit tests 13. NUnit - unit testing framework 14. Log4net - logging framework 15. Cloud based on Azure SDK These are not the latest technologies, tools and libs for the moment but if there are someone thinks that it would be useful to migrate the sample to latest current technologies and versions please comment. Cloud version of the application is based on Azure emulated environment provided by the SDK, so it hasn't been tested on ‘real' Azure scenario (we just do not have access to it). Thanks to participants, Eugen Gorgan who was involved directly in development, Ruslan Rusu and Victor Lungu spend their free time to discuss .NET specific decisions, Eugen Navitaniuc helped with Java related questions. Also, big thank to Cornel Cretu, he designed a nice logo and helped with some browser incompatibility issues. Any review and feedback are welcome! Thank you, Artur Trosin

• Constraint-based expert systems design and development [on hold]

  - by Alex B.

  I would appreciate some recommendations & resources on design and development of expert systems, in particular, knowledge-based & constraint-based (not recommendation) systems. Ideally, your answers should consider the perspective (context) of using a SaaS business model and open source rules engine. How would you advise to address performance, scalability and other architectural criteria? Any other considerations on undertaking such project will be appreciated. Thanks much in advance!

• Linux based audio prodcuction tutorials

  - by thelinuxer

  I have been searching for a while for Linux based audio production tutorials. All I can find is tool based tutorials. For example I found tutorials on how to use jack, ardour, lmms ..etc. What I need is tutorials that teaches professional audio production with opensource/free tools, like those already available for protools and likes. If any one can guide me to any videos/articles available it would be highly appreciated. Thanks.
