The data quality services in SQL Server is a knowledge-driven data quality product. SQL Server Data Quality Services (DQS) enable the user to build a knowledge base and thereafter use it to perform tasks such as correction, deduplication, enrichment, standardization of data.
Apart from this, DQS also provides profiling and enables you to perform data cleaning with the help of cloud-based data services.

* Data Quality Server : It is an SQL Server instance feature consisting of three SQL Server catalogs with data-quality functionality and storage
