Research On Approach Of System Integration Based On MDA

Along with unceasing exposition of traditional methods'shortcomings of Enterprise Application Integration, The enterprises urgently need a more economical, more effective integrated method to integrate all kinds of application systems. This article mainly aims at all sorts of insufficiencies of the traditional technology, using the Web Services'properties of the high loose, the easy extension, the high flexibility and the dynamic integration as well as MDA'merit that the design and the realization will be separated, a new system integration approach based on Web Services and the MDA is proposed.Compared with the traditional integration approach, system integration based on the Web Services demonstrated the obvious superiority, on the basis of the brief introduction to the key technologies that has been used in the Web Services, system integration framework with three levels based on the Web Services is proposed. According to MDA, entire Software development process is driven by the modeling behavior. Then the request of Cross-platform that the system integration need is easy to realize, therefore the proposed integrated framework, especially the third level- core support level is refined with the aid of the MDA technology, the complexity of integrated is simplified by the integration MDA thought to the system integration approach, services transfer technology in the system integration is the most difficult and key problem in the present studies, thus the following starts to introduce how to realize the Web Services dynamic synthesis question based on the MDA technology, the Web Services dynamic synthesis architecture is proposed, in which the establishment and the transformation of MDA model are key points in the research. According to the meta-model transformation profile of MDA, modeling and the model transformation method of Web Services dynamic composition is proposed.Finally take some manufacture enterprise as the example, the model is developed according to the thought of MDA based on Web Services, The establishment as well as the transformation of the model is completed using IBM Corporation's RSA(Rational Software Architect), then the system integration has been realized with the information sharing and reducing the cost and the time.
