MDA- Model Driven Architecture for Software Devlopment
Experienced application developers often invest more time in building models than they do in actually writing code. Well-constructed models make it easier to deliver large, complex enterprise systems on time and within budget.
MDA is a framework advanced by the Object Management Group (OMG) allows developers to build systems according to their core business logic and data—independently of any particular hardware, operating system, or middleware.
This framework is based on UML and other industry standards for visualizing, storing, and exchanging software designs and models.This Framework emphasizes on importance of models in the software development process.
In MDA the software development is done by evolving models of the system to be developed.
MDA software development life cycle
MDA identifies same process that is present in traditional software development for developing a System.
1) Platform Independent Model
2) Platform Specific Model
Platform Independent Model
Platform Specific Model
PIM is transformed into one or more Platform Specific Models (PSMs). A PSM is tailored to specify your system in terms of the implementation constructs that are available in one specific implementation technology. For example, an EJB PSM is a model of the system in terms of EJB structures. It typically contains EJB-specific terms like “home interface,” “entity bean,” “session bean,” and so on. A relational database PSM includes terms like “table,” “column,” “foreign key,” and so on.
At every step the level of Abstraction increases. PIM, PSM, and code are shown as artifacts of different steps in the development life cycle.
The three major steps in the MDA development process
Rational product support for MDAs
Rational Software Architect supports both the principles of MDA as well as the standards upon which MDA is based. It adds full support for MDD, including UML Version 2.0 modeling, code generation, patterns and model transformations, and a new approach to implementing the MDA style of development.
In general purpose category for Java™-based MDA applications IBM provide
MDA toolkit for Rational XDE Java which is an Eclipse plug-in that complements existing patterns and code template features and adds some additional capabilities.
In the domain-specific category IBM Rational System Developer provides a complete UML-based design and development environment optimized for engineering and other types of technical applications developed in C or C++.
In the supporting category, IBM WebSphere Business Modeler is used to model and simulate business processes. As new business processes are developed, models can be exported from the tool and imported into Rational Software Architect or Rational Rose XDE Developer to drive an MDA development process.
