应用元数据开发数据映射辅助工具

数据映射在数据仓库项目中扮演十分重要的角色,它是ETL开发的前提条件,也是ETL开发过程中详细设计的一部分。本文在中国太平洋保险公司(CPIC)建设企业数据仓库(EDW)的项目背景下对企业数据仓库中的元数据应用作了研究,记述一个简单的元数据驱动的数据映射工具的开发过程,以说明元数据对数据集成工具开发的重要性。

Application of Metadata in Development of A Data Mapping Tool

Data mapping in the data warehouse project plays a very important role, it is a prerequisite for the development of ETL, ETL is also in the process of developing the detailed design of the part. In this paper, China Pacific Insurance Company (CPIC) building enterprise data warehouse (EDW) project against the background of the enterprise data warehouse metadata in the application of research, recording a simple metadata-driven data mapping tool for the development process, to demonstrate that Metadata for data integration tools of the importance of the development.
