+# SQL Tuning Sets
+
+A SQL Tuning Set (aka STS) is a database object that you can use as input to tuning tools. An STS includes SQL statements, associated execution context, associated basic execution statistics, and associated execution plans. It enables you to group SQL statements and related metadata in a single database object, which you can use to meet your tuning goals.
+STS can be generated from various sources such as Automatic Workload Repository (AWR), Cursor Cache or Real Application Testing Database Replay.
