摘    要:目的研制异构数据库系统HDBUS(heterogeneousdatabasesunitedsystem),它是一个在Intranet环境下,将分布在网络不同节点上的OracleSybaseSybase及SQLserver数据库服务中的本地库(localdatabase)集成为一个全局库(globaldatabase),并提供全局事务管理和并行查询处理的异构数据库联合使用系统,方法论述了HDBUS实现方法,在HDBUS的设计上提出了两个重要概念及其实现方法,即并行桥(parallelbridge)和异构表连接(heterogeneoustablesjoin).结果与结论并行桥解决了多个数据库服务器的井行查询问题,异构表连接则是异构数据库联合使用中的一项关键技*术。

关 键 词:Intranet  异构数据库  并行桥  异表连接

Abstract:Aim To develop a heterogeneous database united system(HDBUS)that combines the local database of Oracle, Sybase and SQL server distributed on different server into a global database,and supports the global transaction management and parallel query over the Intranet Methods In the designing and implementation of HDBUS two important concepts heterogeneous tables join. Results and Conclu- tion The first concept can be used to process the parallel query of multiple database server, the second one is the key technology of heterogeneous is the key technology of heterogeneous distribute database.
Keywords:Intranet  heterogeneous database  parallel bridge  heterogeneous tables join
