    * A schema is the set of objects (tables, views, indexes, etc) belonging to an account. 
It is often used as another way to refer to an Oracle account. The CREATE SCHEMA statement lets one specify 
(in a single SQL statement) all data and privilege
 definitions for a new schema. One can also
 add definitions to the schema later using DDL statements.
