I have been looking for an article on Indexes as simple and exhaustive as this for long.

Looking forward to the next 2 parts.

Thanks Gail for mentioning that "When an index scan is done on the clustered index, it’s a table scan in all but name." Many folks think that performance is always better with clustered index scan than a table scan.

This article is fortuitous for me since I attended a SQL 2008 Development class on Saturday and this topic was covered most of the afternoon.

Thanks for the review. :-)
