Research On SOA-based Education Information System Interoperability Model

With the rapid development of the computer network technology and communication technology, education is gradually informationized. All the departments of Colleges pay more attention to Informatization Construction. However because the traditional software development platform, development tools, operating system the tightly coupled in the structure, it is difficult to share information resources among various schools and departments.So "information islands" comes into being.Ministry of Education launched the Education Management Interoperability Framework specification, referred to as EMIF.It uses Regional Integration Server (ZIS) and Client Agent model to build to build campus network information sharing and data integration platform without need to change the the existing system.Through summarizing the traditional soluntions this paper researched on education Management Information Interoperability Framework specification and proposed education information system interoperability model by WCF technology based on SOA architecture. This paper also designed and developed the core component of the EMIF region - Regional Integration Server (ZIS), and made it work effectively with the agent and applications to achieve interoperability between education management information systems. It focused on building Web services of the ZIS, security packet communications services, message queuing services, message forwarding service and realized data sharing and interoperability system under distributed heterogeneous environment. This System achieved interoperability of message transmission through Web services and built a communication mode from a single access method to access a wide range of highly flexible system. Through the more stable and flexible asynchronous interaction mechanism provided by the MSMQ message queue,this system sloved the message stability and completed the packet processing and forwarding. This system used Multi-threaded mechanisms to achieve the monitor and the transponders of the respective message queue, and enhance the concurrent process ablity of the message of the system and improved the efficiency of the system.
