Research For Enterprise Application Integration(EAI) Based On Agent And XML

With the constant development of network technology and enterprise's informationization, IT environments of enterprise has been remarked by the characters of distribution and different construction. How to integrate each isolated system and merge existing resources , which have become the development direction of enterprise's informationization. In this case, Enterprise Application Integration (EAI) is brought forward.By joining together business flows, application software, hardware and various kinds of standards, EAI realizes no-sewing integration among two or more enterprise application systems, and makes them carry on business treatments and information sharing like a whole, which improves the efficiency of enterprise and offers flexible business service for customers. Divided by the integrated depth, EAI has three kinds of levels including data, application and business process. Business process EAI is one complete EAI realizing tactic, which makes enterprise's separate systems turn into a continuous system supporting business process, and meets the whole business process demands of enterprise.In this text, we structured one business process EAI framework model —NFMAS based on multi-agent system theory, mobile-agent technology and XML technology, and then explained the workflow modeling and the implement methodology of NFMAS. NFMAS can meet the demands of simple and swift development for EAI and integration of existing system. Four main respects are included in this text, as follows:(1) After discussing the general relation of application systems in enterprises, NFMAS framework is structured based on multi-agent system theory, which includes three function agents, the distributed and different application systems can be conveniently incorporated in the framework by these agents.(2) Information mutual mechanism of NFMAS is set up through adopting mobile-agent and XML technology. The problem of the conversion and storage about different structure data is solved by XML technology. And mobile-agent technology realized the work of data alternation under the different structure environments.(3) Dynamic planning and management of workflow are supported by NFMAS, and management agent is the engine of the workflow. In this text, according to the module structure of NFMAS and management agent, the workflow modeling of NFMAS is described.(4) Different from the general enterprise application system, the implementation of EAI has more risk. According to the structure characteristics of NFMAS, the implement methodology of EAI is discussed in this text.Finally, an integration case that is applied with the thought of NFMAS system is put up, by which the feasibility of NFMAS is verified in terms of experiment.
