Based On Model-driven Architecture, Enterprise Application Systems Development

Model Driven Architecture(MDA) is a general modeling standard for software systems.It is proposed by Object Management Group(OMG), the largest organization of softwareindustry standard around the world. MDA's main content includes: a unified and precisePlatform Independent Model(PIM) should be created at first, then with the help oftransforming tools, this PIM will be transformed automatically to Platform SpecificModel(PSM), which may be based different concrete technologies. Finally, code anddeployment archive will also be generated. Through this process, MDA will improve theproductivity of software, and make it easier to develop platform-crossing systems.This research is based on the basic theories of MDA, and make some extentions to them.The aim of this research is to develop a complete MDA process, which starts from Metamodel design and model creating to model transformation and system generation. Moreimportant things is the extension of the process to the general MDA process. It reflects on aextended UML meta model and a new transformation process which is lighter weighted andeasier to use.In the beginning part of this work, some problems that happen often in the EnterpriseApplications' development will be proposed, then I will give a brief introduction aboutMDA's basic thoery. The main part of this work is composed of 3 topics. Firstly, it will creata Enterprise domain Metamodel, as well as the description of the meatamodel by a UML2profile. The second part is a light weight model transformation approach and its realizationwith several open source softwares and a technical framework. The last part analyzed modelconfiguration management and other possible topics about MDA.
