The tuning advisor will analyze the database and make recommendations for indexesthat would be beneficial to add or remove. It even provides the TSQL commands that will create the suggested indexes. 

The Microsoft Database Engine Tuning Advisor (DTA) analyzes databases and makes recommendations that you can use to optimize query performance. You can use the Database Engine Tuning Advisor to select and create an optimal set of indexes, indexed views, or table partitions without having an expert understanding of the database structure or the internals of SQL Server. Using the DTA, you can perform the following tasks.

  • Troubleshoot the performance of a specific problem query
  • Tune a large set of queries across one or more databases
  • Perform an exploratory what-if analysis of potential physical design changes
  • Manage storage space
