Research And Implementation Of The Heterogeneous Target Platform-Oriented MDA

Model Driven Architecture (MDA) is a new software development framework proposed by the Object Management Group (OMG). Different from the traditional software development, MDA is model-centric, using the model to guide system design, development and maintenance. It makes model separated from implementation technology, which reduces the difficulty of software development and improves the efficiency of software development.With the development of information technology and a higher level of social information, information systems have more and more types of applications, application environments are increasingly complex, and between the different platforms, interoperability requirements are getting higher and higher. Combination of the SOA thought, this paper designs and implements a system of heterogeneous target platform oriented MDA, which can better achieve development of application systems in this complex environment.This paper analyzes the basic theory of MDA as beginning and further studies the modeling and model conversion technologies in MDA. On this basis, for e-government applications, this paper researches the content of following three aspects:First of all, this paper studies the goal operationalization based business modeling techniques, analyzes the PIM of business objectivesin the zero-code Portal platform, and defines the basic elements in the PIM meta-model elements. Secondly, according to the characteristics of the field of e-government, this paper proposes a based on heterogeneous platforms target application system architecture, and analyzes the PSM component model for heterogeneous target platform.Finally, this paper presents a system framework of heterogeneous target platform-oriented MDA. And then, this paper designed and implemented the model conversion module, bridge module, application integration module of the platform and analyzed the mechanism of model and code synchronization.
