多数据库中间件中分布异构数据缓冲区系统的关键技术

Research on Key Technologies of the Distributed and Heterogeneous Data Buffer System in Multidatabase Middleware

对实现系统所需要的关键技术进行讨论,对数据的一致性管理方法进行分析并对传统方法进行改进,对系统的数据复制策略、局部数据源的即插即用机制、缓冲区系统中的数据名空间和系统的安全管理等关键技术进行深入探讨.

The Distributed and Heterogeneous Data Buffer （BHDB） is an important part of multi-database middleware. This paper discusses data consistency management of the system, improves the traditional technology, and lucubrates the data replication strategy,local data source＇ s plug-and-play mechanism,data namespace and system security management, which are the key technologies and the basis of the system realization.
