Explanation/Reference:

Section: Managing Database Performance & Tuning

In Oracle 11g, the SQL Access Advisor can generate partitioning recommendations, index creation

recommendations, materialized view recommendations,and materialized view log recommendations. The SQL

Access Advisor is a tuning tool that provides advice regarding the tuning of materialized views, indexes(Btree,

bitmap, and function-based), and materialized view logs, as well as advice on table and index partitioning.

The SQL Access Advisor provides recommendations by analyzing a known workload and other specified

information. SQL Access Advisor does not generate statistics collection recommendations. This task is

performed by the SQL Tuning Advisor.
