Statement

True-False▾

It is very difficult to grant and manage common privileges needed by different groups of database users using the roles.

Answer

FALSE

Explanation

Define User System Privileges
  • Oracles allows controlling privileges to users using roles.
  • Grant system privileges to roles- then use the roles to manage system privileges.
    • Privileges grant access to perform a particular action or to perform an action on any schema objects of a particular type.
    • Ex. , the privileges to create table spaces and to delete the rows of any table in a database are system privileges.
    • When multiple users access database objects, authorization can be controlled to these objects with privileges.
  • A user can modify an object owned by another user.
