DataFlux Data Management Studio 2.6: User Guide

What Is a QKB? 

A Quality Knowledge Base (QKB) is a collection of files that store data and logic that define data management operations. SAS software products reference a QKB when performing these operations on your data. There are currently two QKBs available: QKB for Contact Information (CI) and QKB for Product Data (PD). These QKBs are not interchangeable. To display the help for QKBs installed at your site, see Accessing Documentation for QKBs.

Data and logic in a QKB are organized into a set of objects called definitions. Each definition defines a single, context-sensitive data management operation. For example, a definition in a QKB might contain data and logic used to parse phone numbers. Another definition might contain data and logic used to determine the gender of individuals by analyzing their names.

When you use SAS data management products to process your data, you specify which definitions the software should invoke. For example, if you are standardizing company names with the Standardization node in a data job, you can specify that the node should use the Organization definition when processing data in the Company field in your table.

A QKB contains definitions developed for use with common types of data such as names, addresses, and phone numbers. There are periodic updates to a QKB with new definitions and enhancements to existing definitions. To download updates to a QKB, visit the QKB downloads page.

You can use definitions in a QKB as delivered, or you can use DataFlux Data Management Studio to customize the QKB by modifying definitions or creating new definitions for use with your own business data. Since a QKB is used by DataFlux Data Management Studio, SAS Data Quality Server, and the SAS Data Quality Accelerators, QKB customizations are automatically available to your entire enterprise.
