Research And Practice Of MDA Software Development Approach With XUML

All the time, the business rules of the organizations and enterprises are continuously adjusted to adapt to the market requirement. As the result, MIS of enterprises must be adapted to requirement continuously.At present, OOP develops rapidly, especially modeling in UML technology, while it has some shortcoming: Firstly, the system models in UML are not executable, and these models can not be verified, thus increase the risk of the stage of system implement. Secondly, with the business rules changing, the system models in different platforms are hardly consistent. The reusability of models becomes poor, so new methods of the MIS system developing and modeling are needed to meet the new requirements or changed business rules to the model and code of the MIS system dynamically and smoothly.In this case, a new modeling technology based on eXecutable UML and RUP(Rational Unified Process) is discussed in this paper, Meanwhile as foundation of MDA(Model Driven Architecture) conception in a way, by which we can get executable, more abstract models and test models to verify models, decreases the risk of project.The groundwork of this text includes:1) Have analyzed the state of development of the present soft Engineering, has introduced MDA software development approach based on xUML;2) Have introduced the basic general pictures of MDA and xUML briefly, has explained executable MDA system structure and relevant basic conception;3) Introduced briefly Rational Unified Process and characteristic, and has explained the lifecycle based on the Rational Unified Process of executable MDA in detail;4) Have introduced basic method and principle based on MDA software development approach of xUML in detail;5) Apply basic method and principle that introduce described above to a concrete project;In this paper, based on Web teaching system of project, this technology is studied and system is modeled by this modeling technology.
