摘要
为了解决企业IT系统对维表缺乏统一管理的问题,提出了在各业务系统定义和使用的维表编码之上,借助元数据建立一套标准维表库,统一管理维度及维度映射关系,为目标系统解决了不同系统数据集中时维度映射带来的数据质量问题。并且本体系提供了维表检索、维表影响分析、维表变更监控等应用,进一步提升了维护的便利性和数据质量问题发现的及时性。
In order to solve the problem of enterprise IT systems, which is the lack of unified management of the dimension table, we proposed a system that establishes a standard dimension table library with the meta-data at the top of the business system definition and use of the dimension table coding. The system can solve the data quality problem that different systems dataset dimension mapping data for the target system. Moreover, this system provides dimension table retrieval, dimension table impact analysis and dimension table change monitor, enhances the ease of maintenance and the data quality problems found in time.
