It is the central part of DQS client application. We can specify the rules that DQS will apply when validating data and the action taken when those rules are violated. As they capture the organizational knowledge, so they are term as knowledge base. Basically they are the rules define for the domains.

The KB contains Domains which is a component of Data Quality. For example a Country Domain can be such that it should not contain any abbreviated stuff and the length of the country must be greater than 3 letters. Now we can have this domain in our knowledge base say CountryKB. Typically, a single KB can have multiple domain values and for every domain we can have rules and validations apply for them. Domains can be either single valued or compound (consists of multiple fields).
