Model Driven Architecture Research

Model Driven Architecture is proposed by OMG in order to solve the problem which the software industry to face today. The key of MDA is that model is act as a very important role in software development period. The whole development process is driven by creating model for the system. The first period of MDA process is to abstract the core model (PIM) which is independent from the detail implement issue and can descript the business rules completely. Then define the different map rules for different implement platform. Then base on these map rules, transform the PIM into an application model (PSM) which depend on the implement platform. At last, transform the PSM into code in some extent.This paper regards the MDA software development method as the main topic. Base on the deeply research on the basic principle, basic architecture, software development circle, model independent, and model transform implement of MDA, this paper also research deeply on the core techniques of MDA such as UML, MOF, XMI, CWM, etc. Base on these research, the formal descript of model transform from PIM to DBMS PSM, EJB PSM and Web PSM are given. This paper also gives the transform rules about how to transform these PSMs into a Code Model. At last, we implement MDA in a real project. This paper descripts the whole development process.
