Can you
do Oracle data warehousing on Standard Edition?
Oracle Tips by Burleson Consulting |
Question:
Much to my amazement, we ordered Oracle
Standard Edition (SE) instead of Enterprise Edition (EE). We pride
ourselves in analytics and I’ve noticed performance has declined greatly
since we migrated to our own servers. I’ve been searching for an article
or white paper describing the benefits of Enterprise vs. Standard.
Considering that we have a data warehouse with ~ 12MM rows, I have a gut
feel that utilizing bitmap indexes and materialized views would improve
performance considerably. Can you offer justification for using
Enterprise Edition for a data warehouse?
Answer:
Yes, you would have a very hard time doing data warehouse of OLAP with Oracle
Standard Edition. It's difficult (if not
impossible) to implement a performant Oracle data warehouse without the advanced
warehouse features (Materialized views, STAR joins, bitmap indexes) that appear
in Oracle EE. In my 15 years working with Oracle, I've never seen a data
warehouse using SE.

a gut feel that utilizing bitmap indexes and materialized views would
improve performance considerably. But, having a something to back it up
would be huge.
