异构分布计算环境中多数据库的集成与互操作是CIMS环境下信息集成的一个主要研究领域。本文在分析这方面研究成果的基础上,结合CIMS环境下信息集成的需求,提出了一种基于视图对象(ViewObject)机制的多库集成与互操作技术,其基本思想是通过视图对象的机制对多种数据源中的数据进行多层抽象与封装,以满足CIMS环境下不同层次的应用集成需求。文中还以公共对象请求代理结构(CORBA)为基础提出了基于对象请求代理(ORB)的多数据库集成与互操作系统VO-MDBS的实现机制。
The integration and interoperation of multi-database in heterogeneous distributed computing environment is one of the main research fields of information integration in CIMS environment. On the basis of analyzing the research results in this field and combining the requirements of information integration in CIMS environment, this paper proposes a multi-library integration and interoperability technology based on ViewObject mechanism. The basic idea of this method is to use the view object mechanism Multiple data sources in multi-layer abstraction and encapsulation of data to meet the different levels of CIMS application integration needs. In this paper, based on the Common Object Request Broker Architecture (CORBA), a multi-database integration and interoperability system VO-MDBS based on Object Request Broker (ORB) is proposed.
