一种通用的数据质量评估控制元数据模型

A Common Metadata Model for Data Quality Assessment Control

为解决传统数据质量评估实现方式灵活性与通用性较差的问题,通过对元数据应用与数据质量评估体系的研究,重点分析了元数据在数据质量评估过程中的作用、数据质量评估维度与评估算法;确定基础元数据、评估控制元数据与评估算法元数据,并构建元数据模型。通过实际应用证明模型具有良好的灵活性与通用性。

In order to solve the traditional data quality assessment approach problem which have poor flexibility and versatility, by studying the metadata applications and data quality assessment system, focus on the role of metadata in the data quality assessment process and data quality assessment dimensions and evaluation algorithms; define basic metadata, assessment control metadata and evaluation algorithms metadata, construct the metadata model. The practical application shows that the metadata model have good flexibility and versatility.
