分布式数据库通用查询对象模型

提出基于CORBA的分布式数据库通用查询对象模型，该模型结合目前最先进的分布式对象技术，异构数据库访问技术以及为了解决异构分布式计算机系统数据传输问题而提出了的数据类型鉴别器技术，为异构分布式数据库系统提供可跨平台移植的，跨数据库查询的具有统一接口的分布式数据库通用查询构件，利用分布式数据库通用查询对象模型概念的实现，成功开发出南方电力调度中心异构分布式计算机信息交换系统软件，给出了使用该软件在分布式异构系统中实现数据通用查询的实验结果，证明是可行的。

Object Model for General Query Distributed Database

Object model based on CORBA for general query distributed database combines technology of distributed object, technology of heterogeneous databases query and technology of data type discriminatior which resolves the problem of data transfer in heterogeneous distributed system and proviedes the same interface component for general query database which can transplant heterogeneous platforms and query and database. Using this model implementation, the author has successfully developed the information exchange soft for heterogeneous distributed system in South Electric Manager Center. At last, the results of tests which realize general query database on distributed system have been given, which proves that this model is feasible.
