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, refer to “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.
Use
the qkbpush.sh script to load updates as described in
Deployment Overview.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, then, as a best practice, we recommend that you customize
your QKB on a local workstation before copying it to the Hadoop master
node for deployment. Then, when updates to the QKB are required, you
can merge your customizations into an updated QKB locally and deploy
a copy of the updated, customized QKB to the Hadoop cluster as you
would a standard QKB. Refer to 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.
Note: To add support for additional
QKB locales, you must license the new locales and then reinstall and
re-deploy the QKB.
