Research and Application of Middleware Technique in Heterogeneous System and Interoperability Environment

The management and operation of a modern enterprise demands its EIS should have the characteristics of distributive, expansible and reusable. It causes the complication of structure designation of EIS and the prominence of interoperability and data sharing among the heterogeneous systems. Middleware technique simplifies the development of EIS by its own structure characteristic and effectively solves the problem of interoperability of system. In this paper, the requirement of EIS is analyzed and the middleware is introduced firstly. Then EIS structure based on J2EE middleware technique is designed. Finally, an accessing middleware model based on Java technique is designed and interoperability is realized in heterogeneous database environment.
