摘要
通过基于组件对象模型 /分布式组件对象模型 COM/ DCOM组件标准开发的事务逻辑组件构成系统功能层 ,活动服务器页面 ( ASP)用于客户端页面管理和组件调用 ,并由微软事务服务器 MTS负责组件管理的方式实现 GSQL语言 .该语言屏蔽了各局部数据库的异构性 ,实现了各局部数据库的并行处理 .采用组件方式集成的异构数据库使得系统的可伸缩性大大提高 。
To implement united use of heterogeneous databases. The system function layer is composed of transaction logic components, which are designed and developed on the basis of COM/DCOM. ASP is used to call components and manage Web pages of clients. And MTS is in charge of administration of components. As a result GSQL language is provided for users and heterogeneity of local databases is shielded with use of GSQL. Parallel processing is implemented in UUHDB. And the system design and implementation based on COM/DCOM component model is feasible and effective, especially for expanding use in more information sources.
