It uses Knowledge Base (KB) for improving the quality of the source data by performing data cleansing and data matching activities and finally exports the resultant data to a SQL Server database or a .csv file

A Data quality project can be created either as a cleansing project or a matching project to perform respective activities and can perform the operation on the same KB.
Cleansing is that KB application that refines the source data in the KB.

Matching is that KB application that performs matching activity based on matching policy in a knowledge base to prevent data duplication by identifying exact and approximate matches, and thereby helps to remove duplicate data.
