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
摘要
Abstract
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 algo-rithms metadatat construct the metadata model. The practical application shows that the metadata model have good flexibility and versatility.关键词
