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
SAS Quality Knowledge Base (QKB) product
documentation page at
support.sas.com. To find this page,
either search on the name “SAS Quality Knowledge Base”
or locate the name in the product index and click the
Documentation tab.
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 Package Files 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, we recommend 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 you would
use to deploy a standard QKB. Copying your customized QKB from a local
workstation into your cluster also means 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.
