Paper Abstract

To solve the problem of data quality in data warehouse, the process of data stream in data warehouse and the factors influencing data quality were analyzed; a method for controlling data quality based on quality grading was proposed and the frame of data quality grading system was established. In each process of ETL, the data quality grading system would execute script to calculate values, such as total, component and standard measures in accordance with the definition of Unit Measure, so as to get representation indexes; and then the quality report would be generated according to the indexes and the quality would be graded. The method is applicable to various data warehouse systems.
