Research On Credit Management Architecture Based On Meta-Model

Based on the software development of Integrated Electronic Commerce Software GECIS, this paper researches the software development of credit management using the method of object-oriented, the idea of meta-model and the technology of MDA.Firstly, the disadvantages of conventional software development method are analyzed. After comparing the method based on MDA to the conventional method, its advantages are expatiated, which can solve the problems of repeating modeling and so on. Then the frame and core criterion are researched. A language of model transformation is pesented. The 4-layer structure of OMG is researched. Then the advantages of meta-modeling and its uses in MDA are analyzed.Secondly, based on the method of object-oriented, the credit management software is analysed and designed on the domain. In the phase of domain analysis, the requirement of credit management is abstracted and described, then use case model and activity model are created. In the phase of domain design, object structure models are created. Also the Design Pattern is used to optimalize the design.At the end of this paper, the model transformation of credit management software is achieved. After comparing the source language to the target language, the rules of model transformation are analyzed. Then the formalized expression of model transformation is designed, based on which the transformations are done.Using the method of MDA can solve the problems of repeating modeling. The model transformation can not only reduces the time in the development greatly, but also improve the software quality and the efficiency of development.
