Design And Implementation Of Integrated Management Information System Of School Of Distance Education Of Southwest Jiaotong University Based On SSH And JBPM

With the rapid development of information & communication technology and update of digitalization and networking in education concepts within universities, it is an important means to improve office business efficiency by information digitalization and networking transformation. Information system is used to help people in daily work; at the same time, it is also expected to offer information supports in decision making and have agilities so as to be adapted to continuous changes in office business requirements.In this thesis, we use Integrated management information system (MIS) in school of distance education of southwest jiaotong university as the research object. According to this background, user requirements are analyzed and research targets are confirmed. Based on technology of Java EE, frameworks of Struts2,Spring and Hibernate are analyzed. Struts2 is a framework which applies idea of Web Work in key design and also adopts some advantages of struts 1. It is a MVC framework which is compatible to both Struts 1 and WebWork and it divides information system into levels, so that coupling of system is decreased and at the same time expansibility is increased. Spring is a light weight container, which uses IOC to implement coupling relationship injections among components so that coupling relationship among components can be minimized and components can be reused easily. Hibernate is a framework for objects relationship mapping, which can implement mapping of java class to database table (or database table to java class). In this way, developers can manipulate database in idea of objects and database migration can also be achieved easily. At the same time, work flow technology of JBPM is also imported in this paper. JBPM is a lightweight work flow management system based on java EE which can be integrated with SSH architecture and offer functions of process definition, deployment, execution and management in environment of any database system on any server. Finally, technology of Single Sign-On CAS is also applied in system of MIS. Based on these technologies mentioned above, with author's experience of design and development of MIS as an example, business functions are implemented with SSH,flow of office business is managed by JBPM and Single Sign-on/Sign-out is achieved through CAS.Finally, sub systems of students recruit, documents flow management and permissions management based on ACL are analyzed in detail. In these sub systems, multiple system levels, main functions and implementation of key technologies are introduced. Currently, MIS is an important and essential assistant in daily business in school of distance education of southwest jiaotong university. With its application, it shows that design objectives are achieved with reliable performances and satisfactory effects.
