Updating and Customizing a QKB

SAS provides regular updates to the QKB. It is recommended that you update your QKB each time a new one is released. For a listing of the latest enhancements to the QKB, see “What’s New in SAS Quality Knowledge Base.” The What’s New document is available on the Quality Knowledge Base (QKB) for SAS and SAS DataFlux Documentation site on support.sas.com.

Check the What’s New for each QKB to determine which definitions have been added, modified, or deprecated, and to learn about new locales that might be supported. Contact your SAS software representative to order updated QKBs and locales. To deploy a new QKB, follow the steps in Packaging the QKB and Installing the QKB Package File with the Teradata Parallel Upgrade Tool. The accelerator supports one QKB in the Teradata database.

The standard definitions in the QKB are sufficient for performing most data quality operations. However, you can use the Customize feature of DataFlux Data Management Studio to modify the QKB definitions to meet specific needs.

If you want to customize your QKB, then as a best practice, SAS recommends that you customize your QKB on a local workstation before copying it to the Teradata database for deployment. When updates to the QKB are required, merge your customizations into an updated QKB locally, and copy the updated, customized QKB to the Teradata node. This enables you to deploy a customized QKB to the Teradata database using the same steps that you would use to deploy a standard QKB. Copying your customized QKB from a local workstation into your cluster also means that you will have a backup of the QKB on your local workstation. See the online Help provided with your SAS Quality Knowledge Base for information about how to merge any customizations that you have made into an updated QKB.
