【Abstract】 Heterogeneous DDB’s Integration is a hot topic and problem in application of MIS. This paper give out one extend model of EAI integrating heterogeneous database. By studying the EAI mode and the middleware technique of database integration,The methods of design and realization of middleware at the extend DDB’s integration mode is discussed in detail. It was proved out that the technique of middleware was valuable in applications for its easy expanding and stability and better updating.更多还原
