摘要
围绕信息系统集成的核心问题——数据集成展开研究,分析和阐述了信息系统集成和数据集成的基本概念,信息系统集成与数据集成的关系,详细介绍了数据集成的模型分类及数据集成的主要难点——数据源的异构性及异构数据源之间数据转换的方法。最后,对数据集成的研究与应用前景进行了展望。
This article focuses on the core issue of data integration in order to analyze and elaborate the basic concepts and relationship between information system integration and data integration. It also introduces a classification model and the main difficulty of data integration, the methods of translation between the heterogeneity of data sources and the heterogeneous data sources. Finally, the future research in the field of data integration is predicted.
