  SQL Server Tips by Robin Schumacher

Intelligent Indexing

This book is not designed for those who are new to SQL Server, so the general indexing discussions that focus on what an index is, the types of indexes, etc. will be bypassed. Instead, this section will explain how best to index for performance. Keep in mind that each database’s workload is different, but the following checklist can be utilized when reviewing a new or existing physical design:

  • Is it known which indexes are and are not being used?
     

  • Do all key tables have a clustered index?
     

  • Have the foreign keys been indexed?
     

  • Have the DML effects on each table been considered?
     

  • Is each index’s uniqueness strong enough to be useful?
     

  • Is each index’s fillfactor set properly?
     

  • Is there an index maintenance plan in place?
