You can use a data quality assessment project to examine the quality of existing data.

You can do a data quality assessment, for example, if you:

• Have implemented a change in the Data quality studio configuration and want to make sure existing data is in line with this change.
• Have imported data without applying data quality policies.
• Want to periodically check the quality level of your data.

In a data quality assessment project, you can apply:

• All validation rules and duplicate check rules of a data quality policy.
• Specific validation rules or duplicate check rules of a data quality policy.
