基于CORBA的分布式通用数据库查询对象模型的研究

Research on CORBA-based Object Model for Distributed General Query Database

本文提出基于CORBA的分布式通用数据库查询对象模型,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通用数据库查询构件。利用分布式通用数据库查询对象模型概念的实现成功开发出某电力部门异构分布式计算机信息交换系统软件。

This paper has presented a CORBA-based model for distributed g eneral query database,this model combines technolog y of distributed object,technolog y of heterog eneous databases query and technolog y of data type discriminator which resolve the problem of data transfer in heterog eneous distributed system,pro-vide the same interface component for g eneral query database which can transplant heterog eneous platforms and query any database.Used this model implementation I have successfully developed the information ex-chang e soft for heterog eneous distributed system in South Electric Manag er Center.
