The Structure of EMIF and its Model for Data Exchange and Message Processing

Among the numerous EMISs (education management information system), the ubiquitous problems such as the difficulties for data sharing and the limited abilities for interoperating make the information systems of different colleges and different departments isolated. Therefore,the committee of Educational Information Technology Standardization (belong to Ministry of Education of China) issued specifications, education management information system interoperability framework, which are good solutions for those problems. In this paper, the framework structures and data exchange models as well as the message formate of EMIF are discussed. The systematic analyses for functional demands of a zone integration server (ZIS), the core component of the EMIF, are made, also its functional model is given. The implementation mechanism and algorithm based on message services, message transportation, and message management for the key functions such as message processing are given, and an instance for providing message processing is presented. Finally, the structure for the data interoperation among multi-EMIS on the campus net based on EMIF is discussed.
