| A new method, which guides the course of software development by models, is provided by Model Driven Architecture (MDA). It improves the reusability and portability of software by separating concept from technology. Since 2000, after OMG proposed MDA (Model Driven Architecture), many domestic and foreign research institutes and large companies have engaged in research in this area, and achieved certain results. A variety of MDA tools sprung up such as the domestically well-known MDA tool trufun, Borland's Together Architect 2006 and so on.Firstly, in this paper, we analyzed and compared the functional properties of the current MDA products/tools. Put their existent question as a starting point, Further pointed out the core issue of MDA- Model Transformation.Secondly, we introduce the field of business process oriented MDA tools which based on the objectives modeling technology - the Magic MDA Platform. Around the workflow, operation, the principal part and the object four elements we launched a detailed analysis to the business process oriented meta model, and be portrayed by MOF.Finally, the model transformation technology as the center, we focus on the transformation method from PIM to PSM of the magic MDA platform, set up a PSM meta model structure, define the description of the transformation rules, in order to give the transformation rules from PIM to PSM of the magic MDA platform. Further give the PSM to code transformation rules; design and implement the magic MDA platform transformation framework.At present, the magic MDA platform has been completed and put into use, good performance. |
