SAS provides regular
updates to the QKB. It is recommended that you update your QKB each
time that 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 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.
Copy
the QKB to the Hadoop NameNode and use qkb_push.sh to deploy it as
described in SAS Quality Knowledge Base (QKB).The definitions delivered
in the QKB are sufficient for performing most data quality operations.
However, if you have DataFlux Data Management Studio, you can use
the Customize feature to modify your QKB to meet specific needs. See
your SAS representative for information to license DataFlux Data Management
Studio.
If you want to customize
your QKB, we recommend that you customize your QKB on a local workstation,
and then copy the customized QKB to the Hadoop NameNode 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
Hadoop NameNode for deployment. This enables you to deploy a customized
QKB to the Hadoop cluster using the same steps you would to deploy
a standard QKB. Copying your customized QKB from a local workstation
also means you 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.
