After the interview I wrote SQL Server Performance Tuning 0verview which explains it on a very abstract level (high level) but I also realize that this concept might not be that easy to grasp when it actually comes to building indexes and there are a few great books on this subject however some people with less experience might find them too advanced so I decided to create a few videos that are more suitable for Junior people and those new to this concept and below is the first series that cover basics of Non Clustered Indexing. Which you can also find in our new YouTube Playlist called SQL Server Performance Tuning and Query Optimization
Video 1: Non Clustered Index Basics
Video 2: B-tree
Video 3: Execution Plan and Time Statitics
Video 4: Included Columns
Video 5: Filtered Index
There is much more to indexes that our first 5 videos but it might a good starting point and we hope to add more soon.
p.s. We fixed comments link (I think)What is your experience and opinion about it? The same, different or maybe depends?
