对多应用系统的数据集成

针对解决因分时建设开发造成应用系统的应用环境和数据规范不一、信息孤岛严重等问题，而产生的数据集成、展现的需求进行了分析，提出了2种集成策略。对数据的采集、抽取、转换和加载处理过程进行了分析探讨，集成的数据可以以数据视图的形式直接给用户使用或展现，也可以用来构建数据仓库，进行深入的分析和挖掘。

Data Integration of Enterprise Application Software Systems

In order to deal with such problems as inconsistent application environment and data criterion, information islands, etc., caused by different construction teams and periods, this paper presents some data integration methods to address the issue of data integration in Enterprise Application Integration. The data extraction-transformation-loading are also discussed. The integrated data can be sent directly to users by data view, and be used to construct data warehouse for data analysis and mining.
