L’approche Compuware: Model Driven Architecture

Object Management Group : Support de l’industrie OMG : 800 membres / 40 organisations Borland Son but: Résoudre les problèmes d’intégration de systèmes Augmenter la productivité Comment : Produire des spécifications, des standards. Exemples : CORBA UML MDA Codagen Technologies Compuware IBM InteractiveObjects SUN OMG has about 800 member companies, OMG continues to be the largest software standards organization of its kind. There are over 40 organizations that are committed and support the MDA. OMG’s focus has always been, and still is, to help users solve integration problems, in a productive way, by supplying open, vendor-neutral interoperability specifications, which is being achieved by the widely adopted CORBA standard . On the slide I have taken an extract of some of the companies that are fully committed to making MDA a success. So based on this I believe that in the next 2 to 3 years we will see the MDA will reach a maturity level status. Currently today, you see that MDA is been spoken about more and more and that vendors are announcing their support for MDA but there is a big difference between supporting it and actually implementing the MDA in its entirety. MDA will only deliver on its productivity promise when the transformations between the PIM and PSM and between the PSM and Code are automated. Currently one of the tools that is truly doing this is OptimalJ. Ruud will explain how our competitors are currently do this, or should I say not. It’s not only the support from vendors but as you can see on the slide there are a number of key analysts endorsing the MDA as the only way to move forward. Here we see Aberdeen’s take on MDA but analysts such as Meta, Gartner Group and Giga, to mention a few, have been quoted in saying that model driven and pattern based development is the way to go. For example Richard Buchanen VP, Meta Group was quoted in saying “If it’s easier to manage change using MDA then that’s the way to go” Together

La vision MDA Une nouvelle manière de spécifier et de construire des systèmes Basée sur la modélisation UML Modéliser au lieu de programmer Finance E-Commerce Santé Plus …... Transport Espace Fabrication Télécommunication MDA’s vision is define a new way of specifying and building systems which is based on modeling with the UML. The MDA captures the use of UML for more than just pretty pictures. For example in the past and even still today. You have designers modeling a system system. All these pretty pictures that are collected and bound into a document and sent over to the developers. What do you think the developers do with them? Most of time its put to one side and forgotten and developers carry an as normal. Or else its used at inception but over time the application is miantained but the model is never kept in never kept in sync. MDA’s vision is merge these two worlds and I’ll explain later how this will take place. MDA is not the next big thing. Let me explain. The problem is that every year we see a new infrastructure being introduced. If we look in the last 10 years. C C++, Java, J2EE, Web Services, .NET and who knows what’s coming out next year. But the nice thing about MDA is that it transcends the implementation infrastructure. Its simply a way of using UML to develop application architectures that be hosted on many different implementation infrastructures in the next years which will last 20 years. So in the meantime people aren’t worried about what the architecture of the application is and how I can ensure the architecture of my application outlasts the infrastructure that implements because that what weve got to do.

Les spécifications en MDA PIM Le Modèle Indépendant de la Plate-forme (PIM) représente les fonctionnalité du business et sa conduite sans rentrer dans les détails techniques. PSM Applique une correspondance standard pour créer ou générer un Modèle Spécifique à la Plate forme (PSM). Ceci à partir du PIM. Code Model Créer ou générer le code pour le PSM Platform Independent Model Platform Specific Model Intégration Lets now look at how applications are developed using the MDA. Step 1. All MDA development projects start with the creation of a Platform Independent Model(PIM), which is expressed in UML. The PIM expresses only business functionality and behavior. Built by business and modeling experts working together, this model expresses business rules and functionality undistorted, as much as possible, by technology. The clarity of this modeling environment allows business experts to ascertain, much better than they could if working with a technological model or application, that the business functionality embodied in the PIM is complete and correct. Another benefit: Because of its technological independence, the PIM retains its full value over the years, requiring change only when business conditions mandate. Step 2. Once the first iteration of the PIM is complete, it is stored in a MOF based Repository and input to the mapping step which will produce a Platform-Specific Model (PSM). To produce your PSM, you will have to select a target platform or platforms for the modules of your application. Such as J2EE, .NET etc. Step 3. Once the PSM has been created/generated, the 3rd and final step is to generate the code/implementation model. This will create/generate all of the files the platform requires. When I talk about platforms, I’m referring to the application server(s) your application will run on and programming languages, such as Java, C++ or C# your application will be generated into. This will result in a first cut working application, which can be further enhanced through the MDA process or by hand-coding. Take note that the mapping standard between PIM, PSM and the Code Model has been defined by OMG but the implementation not. MDA compliant tool vendors have implemented portions of the MDA, but OptimalJ is one of the few tools that has implemented the MDA completely to automatically generate a complete application from a PIM to PSM and finally to the Code Model, which I will explain in my next slide.

MDA Domain Model Platform Independent Model Platform Specific Model Code Model Now lets take a look at how OptimalJ has implemented MDA in its architecture? In line with MDA, there is a clear distinction between the models and the implementation of application components in OptimalJ. The models in OptimalJ have various abstraction levels, which include: The OptimalJ Domain Model, which maps to the MDA Platform Independent Model (PIM). The Domain Model defines the business domains without any specific application detail. It is defined by modeling the business application’s functionality and behavior, domain-specific information based on the Meta Object Facility (MOF) and Common Warehouse Model (CWM) in UML. The Domain Model is transformed automatically into an OptimalJ Application Model, which maps to the MDA Platform Specific Model (PSM). The Application Model defines the application, based on a chosen technology, which in the case of OptimalJ is J2EE. It describes what is to be generated in order to implement the application, by providing a logical overview of the components contained within each tier that makes up the application. The transformation from the OptimalJ Domain model to the application model takes place automatically via our Technology patterns. Finally, the Application Model is transformed automatically into an OptimalJ Code Model, which maps to the MDA Code Model. The Code Model defines the generated application code. In the case of OptimalJ, once the Web tier, EJB and DBMS tiers have been defined in the application model, the code implementations of defined components can be generated i.e. the Java classes, SQL scripts and other technical items that are needed for the components in the models. The transformation from the OptimalJ Application model to the Code model takes place automatically via our Implementation patterns. Both the Technology and Implementation pattern form part of Technology patterns, which will discussed in further detail in the “Patterns used in software development” webinar presented by Ton Blankers.

Conclusion

La technologie évolue surtout dans le monde J2EE Application Framework JDK 1.3 JSP 1.0 Servlet 2.2 EJB 1.1 JDBC 2.0 JSP 2.0 Servlet 2.3 EJB 2.0 JCA 1.0 JSP 3.x Servlet 2.4 JDK1.4 Lets have a look at another challenge and that is to keep up with changes in technology. Although everything is standardized in the Java world that doesn’t mean you don’t have to cope with technology change. As standards evolve and new functionality will be added you have to make a decision which new version of technology you are going to implement and when. The costs of technology change are hidden in many cases because what you see in a lot of projects is that adding new functionality and upgrading to new versions of technology are done in one and the same project. <Ask your audience if they do the same and ask them if they have ever made separate calculations for technology upgrades and functionality upgrades for a project> Lets have a look at what typically happens in an application over time, when new versions of technology need to be implemented in subsequent versions of the application. Of course with version 1 of the application everything is still under control. In the application a fixed set of standards are implemented. Lets have a look at version 2.3 of the application.

Les Promotions package Promotion OptimalJ has 4 cornerstones: - Model-based - CBD - Pattern-based - Rule-based We see 3 groups of models: We have the domain model, that is aimed at the business level. It is where you model your business and completely technology independent The development and integration model are technology dependent (EJB), but are code independent. We could replace for example the current development model with a .Net model based on the DNA architecture. Finally we have the real source code. From the domain model, the development models are generated and from the the development models the code is generated. The 3 models are not 1-1, but have different abstraction levels. So to generate from one abstraction level to another, you need to add knowlegde and this is done in the form of patterns. It is not a one time generation, the links between all model element are saved, so we can change the models manually and regenerate to propagate all the changes to the related models, without losing the manual changes. We are also working on the integration model, consisting of connectors to the outside world (for example CICS) and transformations. we discriminated 7 layers of transformation (for example data transformation, API transformation, protocol transformation). Next step is to upgrade the domain model to a full flash business model, by adding the process and organizational model. Of course we have this functionality already in optimal flow, but we want to move to one unified architecture. At this moment we are adding this integration modules as add-ons to the OptimalJ product. the domain model is part of the Optimalj product that that will change in the future. We move to (at least) 3 products, once each of these products have enough critical mass to stand on its own. The integration part is being development by Loek Gherings group, The business Product will be developed by Ronald Verloo group and The optimalJ product will move to Herman Meeuwsen groups. The vision to reality group will focus on the architecture and foundation of these products. If you want to look at the optimalJ product in action, please visit one of the demo areas. Henk will show how to generate applications from the domain model. wim will show how the models are synchronized. Arjan will show the pattern for wireless devices and Eric van HInte will do the graphical editor demo's.

Les autres possibilités de modélisation

Le Modèle When the model is built, the business rules are added and the application is generated. Changes will be made to the application, both during development and after the first release of the production version of the application. This is where the active synchronization comes in. Active synchronization ensures that when a developer makes changes to the models, model and code are kept in sync automatically. Active synchronization is a smart process as it recognizes which pieces of the application are affected by the change and which not, only re-generating the modified components. This ensures that the impact on the application will be minimized. In addition, the active synchronization functionality distinguishes between generated code and code developed by a developer. The process will preserve the developer extensions.

Les bénéfices de MDA Intégrer les systèmes, les implémentations actuelles et futures Simplifier le changement d’infrastructures Pérenniser les applications Réduire les coûts pendant toute la durée de vie de l’application Augmenter le “ROI” « Les entreprises qui suivront la démarche de MDA, soit la séparation de l’architecture de la technologie et de la technologie de déploiement, feront un grand pas en avant et rendront leur infrastructure informatique plus souple, apte à s’adapter aux transformations de l’entreprise, et libre d’intégrer de nouvelles technologies. Cette souplesse est également la garantie pour les entreprises d’un excellent ROI en matière d’investissement informatique. » Michele Rosen, IDC The benefits of the MDA are significant-to business leaders and developers alike : It allows you to integrate what you’ve built, with what you’re building, with what you will build in the future. To quote OMG “…. MDA is always ready to deal with yesterday’s, today's and tomorrow’s ‘next big thing’” Its remains flexible in the face of constantly changing infrastructure. MDA provides a solid framework that frees system infrastructures to evolve in response to a never-ending parade of platforms, while preserving and leveraging existing technology investments. It enables system integration strategies that are better, faster and cheaper. It reduces costs throughout the application lifecycle, extending beyond design and coding stages through deployment and into maintenance and, ultimately, evolution of the application, which results in lengthening the usable lifetime of software and application systems Reduction in development time when building and implementing new applications, without sacrificing application quality but rather improving it. MDA increases the return on investment through the reuse of applications and domain models, which in turn can be adopted to ongoing business and technology changes. It allows a software environment to evolve and change while the business model (PIM) remains stable. This stable base is necessary to cope with the constantly changing environment of today’s market.
