The total number of these views depends on the Oracle version, but is in a 1000 range. The main built-in views accessing Oracle RDBMS data dictionary tables are few, and are as follows: ALL_OBJECTS – list of all objects in the current database that are accessible to the current user;
The terms schema matching and mapping are often used interchangeably for a database process.
