The Research And Development Of Enterprise Information System Based On Java And XML

With the globalization of economic and rapid development of Internet, the information becomes very important to enterprises. Modern enterprises face a great deal of information ereryday, how to do with and use this information rightly and rapidly is an important problem to enterprises. Person information is very basic for a enterprise, it includes Person basic archive, wages, education training, individual experience, individual chievements and outcome, work redeployment,the title of a technical post, cadre appoint and remove and so on. This information is large and complex. If they are managed by Person Management Software(PMS) of computerized management, work efficiency of enterprises will be improved greatly and manpower resource will be arranged correctly.The paper describes the development process of Person Management Software based on Java and XML technology. Firstly the paper introduces the development and change of architecture of Enterprise Information System(EIS), analyzes advantages of multy_layer architecture and feature of the B/S mode.Secondly the paper introduces Java relative technologies, including JSP, Servlet, JavaBean, JDBC etc, and explains the features of these technologies and XML' s ways of access to database. Thirdly the paper describes the development process of Person Management Software from system requirement analysis, database design and realization of three_layer architecture' s each layer. The paper emphasizes design and realization of Person Management Software' s several key technologies, including the design of main interface, login module, insert module, pagination display module, alter and delete module, database connection, database connection pool module, means of XML access to database, and last the paper discusses the system' s security and the resolve of JSP Chinese problem.The PMS adopts multy_layer archtecture,designing client layer, logic layer and data layer separately. The client layer is designed with JSP and JavaScript;logic layer with JSP and Servlet technology;data layer withJDBC and JavaBean, and main function of system is realized in logic layer. The system designs login security and insert, alter, seek and delete function.The paper uses Java,XML technology and multy_layer archtecture to realizes PMS, and explains the PMS development process from the system requiement analysis, function design, realization idea of key function and the pragram flow chart.
