Research And Implementation On Model Transformation Method In MDA Model Transformation Platform

The software technique based on Web has been developed unprecedented with the continuously improvement in informatization and electronization of the society. Meanwhile, it has been made more difficult that synchronized maintaining between the models generated in designing stage and the codes, in traditional software developing with the push of the item.The changing of the demand of the customers and implementation technique causes the changing of the system code continually. These lead to the inefficiency in software development, interoperability , portability and high maintaining cost. In order to solve the problems above and accelerate the continuously development in software technique, OMG(Object Management Group)bring forward MDA (Model Driven Architecture) which is a new way to describe and establish system. This technique is more and more concerned and researched in order to achieve new change.Nowadays, the research of MDA is mostly focus on the model transformation technique which is the point of MDA implement. This article contains the works below combining the characters of Web application in research and implement.(1) The article designs the model tansfermation platform facing the Web application system and confirms the model transformation modul as the core, aiming at the MDA research situation and lack of tools.(2) The artielce anlysizes and designs the input and output models of the model tansfermation platform. It combines the functional demands and non-functional demands (MVC), and describe the source model as platform imformation model, interface model and business model, meanwhile describe the business model as static structure model and dynamic structure with details. And source model is formed by Web configuration files, architecture model and association model. It abstracts the key information of association model and association model according to the character of Web application to make the target system sytisfied by the MDA demand.(3) It indroduces the model implement based on the mapping of meta model with RDL rule aiming at the research and implement demand in model transformation platform. It defines the mapping relationship between the source model and target model totally and partially so that the details of the demand of model transfermaiton could be met and transformation rules could be compiled. And it improves the model transfermaiton quality and comfirms the implement of model transfermaiton process through increasing the information of steps saving the transfermaiton and model transfermaiton validation.(4) It brings out the GUI of the model transformation platform improved the practicability and friendliness of the software through interactive interface, and additionally brings forward the thinking of extension of model transformation platform.(5) It furtherly improves the flexibility of the method through capturing usre's demands in a Web application system development and completing the transfermaiton using the method mentioned above.Finally, it summarizes the research and brings forwords the prospect.
