Data quality & master management application will check the data for required values, valid data types, and valid codes. Application will also configure & correct the data by providing default values, formatting numbers and dates, and adding new codes.
To apply data quality management to the data loaded into the system, application will configure data quality management rules (or check & validations). Checks & Validations would perform a variety of repair, clean up, and standardization functions on incoming identity data values, such as properly formatting numbers, identifying and correcting clerical or transposition errors, and identifying and correcting intentional inaccuracies.
Once the data quality is in place, the data needs to be aggregated & stitched for building a 360 degree customer view that addresses customer needs in the best way possible.
