| This paper studies an existing distributed database synchronization model and proposes an architecture program of distributed heterogeneous databases synchronization which based on the integration of JMS and Web Service in order to improve system capacity and construct Information platform for SMEs. It Implements passing messages between systems with the use of JMS and achieves read and write of cross-platform data with the use of Web Service technology.It improves two-phase commit protocol in distributed transaction processing, reduces the probability of occurrence of system deadlocks and ensures the consistency of data distributed database effectively. It inducts the cache technology in enhancing the performance of distributed database system, and proposes a way to deal with integration of caching and database and ensures the validity of cached data effectively. The structure program is for program developers and they can develop efficient, convenient, distributed database system based on this structure program. Finally this structure program is used in background management system of mobile phone alerts service and the results show that it can meet the business need of synchronize distributed heterogeneous database system. |
