数据仓库元数据管理系统

本文首先对元数据的基本概念和作用进行了介绍,然后对元数据系统的软件架构进行了设计,并对用到的关键技术进行了说明,用到的关键技术包括:“血缘关系”,元数据抽取、转换、加载以及SQL数据的埋点、采集等。实现了将数据界面化展示,可完成数据字典查询、表对象查询等,使用户可以很轻松的获取想要的数据,大大地提高了开发的效率。

This paper first introduces the basic concepts and functions of metadata, and then designs the software architecture of the metadata system, and introduces key technologies such as“blood relationship”, metadata extraction, metadata conversion, metadata loading, as well as the burying and collecting of SQL data, the article also realizes the interface display of data, it can complete data dictionary query, table object query, etc., so that users can easily obtain the desired data, greatly improving the developments efficiency.
