SYSTEM PRIVILEGEA system privilege is the right to perform an action on any schema objects of a particular type.
Like, the privileges to create tablespaces and to delete the rows of any table in a database are system privileges.
There are over 60 distinct system privileges.
System privileges that use the ANY keyword enable you to set privileges for an entire category of objects in the database. PUBLIC privileges are granted to every user in an Oracle database, and can be granted to roles and as users.
