On January 4, I’m speaking about index internals for the Performance Virtual Chapter of PASS (http://performance.sqlpass.org). Here’s my session abstract:
SQL Server provides two kinds of indexes for relational data: Clustered- and Non-Clustered Indexes. Both of them can be defined as unique and non-unique. In this session you will learn how to use Clustered- and Non-Clustered Indexes in your database and how you can improve the execution time of your queries with those indexes. Furthermore we will have a look into the concrete storage details of both indexes and how they differ when you define them as unique and non-unique and what's the tradeoff between it. Finally you will get some best practices how to deal effectively with Clustered- and Non-Clustered Indexes in your database.
I’m really looking forward to this great chance, and hope that you attend my session.
