Also, I've found that using dbms_stats.gather_table_stats can give better statistics than Oracle's recommended dbms_stats.gather_schema_stats.

A schema in an Oracle database is defined as a collection of database objects and is owned by a database user.The schema name shares the same name as the user due to which both the terms are sometimes used interchangeably though they are not the same. The CREATE SCHEMA statement does NOT actually create a schema in Oracle. (Find out how to create a schema in Oracle.) The CREATE SCHEMA statement is used only to create objects (ie: tables, views) in your schema in a single SQL statement, instead of having to issue individual CREATE TABLE statements and CREATE VIEW statements. You can access objects of any schema if your user has the access to the objects of that schema.
