Research And Implement On MIS System Based On Service-oriented Smart Client

With the development of information technology in the enterprise information system, the traditional system exposes a rigid structure, not easy to deploy and update limitations. To overcome this deficiency, Smart Client emerges, its application demonstrates the tremendous superiority, and soon become a hot point.First of all, this paper introduces the technology and characters of Smart Client and SOA, and detailed analyze the Smart Client framework, SOA Protocols. Second, the paper discusses technical problems in research. In offline operating, the client cache minor mapping data in local which it operations base on and synchronizes the data with server while regain the connection. Due to importing Web Services to encapsulate the business logic. Comparing with the traditional middle ware technology, the method increases the develop efficiency, commonality, distributives and Platform diversity. Then encapsulating those obtains data, and format to XML pattern, so as to implement data integration within the heterogeneous system.At last, according to the hospital demand the paper develops a enterprise information management system for verifying the maneuverability of model, and then according to the possible technology difficult within the development of system, the paper give corresponding answers. It resolves the difficulties about the transplantation, maintenance and upgrading of C/S and slow response of B/S and dependence of the worse customer's experience and network Problems, and provide users with an online and offline smart system.
