Research and Application of Model Transformation Based on MDA

Model driven methods are to solve the low efficiency,poor portability in software development,model transformation is the key technology in development of application tools based on Model Driven Architecture(MDA).This paper introduces the theory about MDA technology,proposes the model transformation method of Platform Specific Model(PIM) to Platform Specific Model(PSM) based on pattern,according the transformation method to establish the transformation rules,it is verified in an instance of MDA application development,this method realizes the transformation from platform independent model to enterprise Java bean model of J2EE in platform specific model.
