Research of Data Quality Control Based on Quality Grading

摘要：

This paper puts forward a method of data quality control by data quality grading, which would be achieved through the establishment of a set of quality indexes and a quality validation framework. Different types of data were audited by means of defining and measuring the input and output data in ETL units, so as to acquire data representation indexes. Based on these indexes, data quality grading was completed.
