MDA-based Modeling and Transformation Approach for WEB Applications

Platform independent models (PIMs), platform specific models (PSMs) and the transformation between them are key technologies in OMG's MDA. But there is no effective solution until now. Starting from software architecture modeling, a modeling approach was proposed to build platform independent models for Web applications by extending UML and adding user-interface presentation views. Based on this approach, an abstract algebra method is employed to realize the transformation from PIMs to PSMs according to the mapping relations between architectures. This solution makes better use of traceable links established by software architecture between the phases of software lifecycle, and it can support model driven software engineering effectively for keeping independency for PIMs. Software architecture becomes the basis of system analysis and model transformation at the same time. J2EE was used as a target platform to help interpreting the process of using this approach
