On July 10th 2013, I gave a presentation with the Professional Association for SQL Server (PASS) DBA Fundamentals Virtual Chapter. The topic was Indexing Fundamentals and there were some questions that we did not have time to answer. I have combined similar questions and given one answer to cover the specific topic.
Indexing is an integral part of SQL Performance and Architecture. In this presentation we will cover the basics of Clustered and Non-Clustered Index structure and function. Additionally, we will discuss the B-Tree structure, index density (fill factor), page splits, and performance considerations. Finally, there will be a brief discussion of index maintenance.
