摘要
提出一个基于CORBA(commonobjectrequestbrokerarchitecture)的即插即用的异构多数据源集成系统的设计方案.由于采用具有较强描述能力的OIM(objectmodelforintegration)对象模型作为集成系统的公共数据模型,该系统不仅能集成各种异构数据源,包括数据库系统、文件系统、WWW上HTML文件中的数据,而且能集成随时插入的新数据源中的数据.着重讨论系统的总体结构、OIM对象模型。
A scheme, designed for integration of heterogeneous data sources based on CORBA(common object request broker architecture) in a plug & play way, is put forward in this paper. An object model, named OIM(object model for integration), is proposed as the common data model for integration. The system can integrate various heterogeneous data sources, ranging from database systems, file systems, to hypertext files in World Wide Web. Any other data source, if wrapped according to the specified way can be integrated into the system, whenever necessary. The architecture, OIM, query processing, user interface design are introduced in some detail in the paper.
