ANALYZING SYSTEM AND ANALYZING METHOD FOR DATA QUALITY PROBLEM

摘要

A system and a method for analyzing a data quality problem are provided to analyze the data quality problem of a database deeply, quickly, and easily by generating and displaying an SQL(Structured Query Language) automatically based on metadata defined to the database of a legacy system without database for analyzing a data flow analysis and a detail analysis. A data quality management system(300) includes the target data(310) of which data quality is analyzed. A meta system(200) includes the metadata for the target data. The data quality management system analyzes causes of the data quality program by utilizing the metadata for the target data. The target data is extracted from the database of which the data quality is analyzed. The data quality management system includes the data of a predetermined table for the target data, points a target table to display a flow tracing result, and inquires a target data list by utilizing the metadata related to the data flow.
