随着社会的发展, 越来越多的企业开始将工作重心向集成体系结构转移。因此,对异构
信息源集成的要求是非常迫切并会长期存在下去。本文提出了一种基于Java 的关系数据模型(JIDM)作为集成系统的公共数据模型。在该模型的基础上,介绍了全局模式、输出模式以及局部模式之间的映射关系,解决了JIDM 模型与关系模型、XML 文件以及面向对象模型之间的映射问题。
关键字: 信息集成,模式映射,关系数据模型
Abstract: With the development of the society, more and more enterprises have set up to change their focus to the structure of system integration. So, the needs for the integration of
heterogeneous data sources will be urgent and last long. The dissertation presents a common data model (JIDM) which is a relational data model based on java. The mapping between global schema, export schema and local schema is presented based on the model, which solves the problem of mapping between JIDM and relational data, XML files, object-oriented data model.
