Using the Default Knowledge Base
You can use the default DQS knowledge base, DQS Data, in the following ways:
Quickly start and run a cleansing data quality project using the default knowledge base without first having to create a new knowledge base in DQS.
Run the Domain Management, Knowledge Discovery, or Matching Policy activities on the default knowledge base. To do so, click Open Knowledge Base in the Data Quality Client Home Screen, select the DQS Data knowledge base in the Open Knowledge Base screen, and then select the required activity in the Select Activity area. Click Next to proceed.
Create a new knowledge base using the default knowledge base. To create a knowledge base from an existing knowledge base, see Create a Knowledge Base.
