Microsoft SQL Server 2008 collects statistical information about indexes and column data stored in the database.

By default, SQL Server 2008 also creates and updates statistics automatically, when such an operation is considered to be useful. This paper also outlines how these defaults can be changed on different levels (column, table, and database).
