基于元数据的通用数据质量评估工具

摘要

In order to solve the traditional data quality assessment tool's problem that have poor flexibility and versatility, by studying the metadata applications and data quality assessment implementation technology , focus on the role of metadata in the data quality assessment process, data quality assessment meta-data abstraction and the members of meta-data. The tool architectureis is determined, metadata model, and implementation tools are constrcted. The practical application shows that the metadata model have good flexibility and versatility.%为解决传统数据质量评估工具的灵活性与通用性较差问题,通过对元数据应用与数据质量评估实现技术的研究,重点分析了元数据在数据质量评估过程中的作用、数据质量评估元数据抽象及元数据的组成.确定工具体系结构,并构建元数据模型,实现工具.通过实际应用证明工具具有良好的灵活性与通用性.
