摘要 首先提出了数据仓库中数据集成的一个总体框架 ;然后探讨了数据集成在数据仓库设计方案中的作用、所要解决的问题、工作流程等 ;最后 ,介绍作者依据这一框架所开发的”铁路货票信息综合利用系统数据仓库解决方案”的数据集成工具DWE DI. The remarkable characteristic of data warehouse is data integration. In this paper, we propose a frame for data integration in a data warehouse, and discuss the functions, problems, and workflows of the data integration. We introduce a data integration tool developed for data warehouse solution of railway freight information synthetical exploitation system according to this frame.
