Saira Yes, typically an OLTP system has no history. It has only a "now". For historical trends you should move data to a data warehouse. This will free up processing resources as well.
I would start by visiting Ralph Kimball's web site http://www.ralphkimball.com. He has many articles posted that will get you started, particularly the oldest articles. His books are really great as well. Dennis Williams DBA, 40%OCP, 100% DBA Lifetouch, Inc.

What are best practices? Is anyone able to recommend websites, articles, **books**, or share similar experiences to point me in the right direction?
