Climbing the SQL Server Index B-Tree

You’ll find a lot of Word of Mouth (WOM) advice out there about SQL Server performance, especially
when it comes to indexes. Some of the things you have probably heard are:
 keep clustered index width small
 unique indexes perform better
 keep non-clustered index width small
 compressed indexes have fewer logical reads
 add one index for each column

But how do you know if this advice is good or bad? Did you know that there is a way to look under the hood at the actual index pages to see how the data is stored, and how it’s stored differently when data is compressed? Using this information, you can prove or disprove the WOM advice.
Attend this demo-heavy session to learn how the SQL Server optimizer uses indexes. It’s all about
performance, and the right indexes will give your application a big performance advantage.
