What is the use of Roles?


  • "REDUCED GRANTING OF PRIVILEGES - Rather than explicitly granting the same set of privileges to many users a database administrator can grant the privileges for a group of related users granted to a role and then grant only the role to each member of the group.
    DYNAMIC PRIVILEGE MANAGEMENT - When the privileges of a group must change
  • only the privileges of the role need to be modified. The security domains of all users granted the group's role automatically reflect the changes made to the role.
    SELECTIVE AVAILABILITY OF PRIVILEGES - The roles granted to a user can be selectively enable (available for use) or disabled (not available for use). This allows specific control of a user's privileges in any given situation.
    APPLICATION AWARENESS - A database application can be designed to automatically enable and disable selective roles when a user attempts to use the application."
