When you create an Oracle Database, the user SYSTEM is also automatically created
and granted the DBA role.
The SYSTEM username is used to create additional tables and views that display
administrative information, and internal tables and views used by various Oracle
Database options and tools. Never use the SYSTEM schema to store tables of interest to
non-administrative users.
