Research On Integration Platform Of Message Service Based On EMIF

With development of the educational information based on Information Platform of Computer Network in School, the problem in data sharing and exchanging becomes more and more visible and important. As a result, a series of criterions in educational Information management is needed urgently. Education Management Information System Interoperability Framework is a kind of such criterion, its purpose is to solve the differ of Data Formats and difficult to integrate. This criterion describes a data sharing and integrates Platform by the model of Agent/ZIS without changing legacy systems. Under such backgrounds, this paper make a study of the ZIS, explores how to solve the problem in data sharing and exchanging among the variable system and database system.In this paper, we discuss three kinds of mechanisms for exchanging data. By analyzing EMIF and the characteristic of Education Management Information System, a schema of key component named ZIS in the EMIF is built up. In the schema we focus on the services of message transform, the services of queue and Security of data exchanging. A prototype system of data sharing and exchanging in the distributed and heterogeneous systems is also implemented. In the prototype system, we use HTTPS to offer the message transforming and the security of data exchanging. In order to guarantee the storage of message steadily and permanently, we use JMS to offer the storage of message queue. We also design a component named Router to transform message. It is a good scheme to solve the problem in data sharing and exchanging. Because of adopting the component design principle, the application integration frame of the component based loose coupling enterprise is built up; the complete system can be constructed by assembling these components in a plug-and-play fashion. With the interoperation of ZIS and user agent, the system can discover and retrieve information in an open and dynamically changing environment.
