Welcome to the Database Engine Tuning Advisor tutorial. Database Engine Tuning Advisor examines how queries are processed in the databases you specify, and then recommends how you can improve query processing performance by modifying database structures such as indexes, indexed views, and partitioning.

Database Engine Tuning Advisor provides two user interfaces: a graphical user interface (GUI) and the dta command prompt utility. The GUI makes it easy to quickly view the results of tuning sessions, and the dta utility makes it easy to incorporate Database Engine Tuning Advisor functionality into scripts for automated tuning. In addition, Database Engine Tuning Advisor can take XML input, which offers more control over the tuning process.
