When you use the Database Configuration Assistant to create a database, Oracle automatically creates the data dictionary. Thereafter, whenever the database is in operation, Oracle updates the data dictionary in response to every DDL statement.
The data dictionary base tables are the first objects created in any Oracle database. They are created in the SYSTEM
tablespace and must remain there. The data dictionary base tables store information about all user-defined objects in the database.
Table B-1 lists required scripts, which are run automatically when you create a database using the Database Configuration Assistant. They are described here because you might need to run them if you create a database manually. To run these scripts, you must be connected to Oracle as a user with SYSDBA
privileges.
