Chapter 13 Managing Database Access
A system privilege is a set of rights assigned to a database user, group, or role.
You have to define these privileges in order to complement the definition of the different database actors. System privileges draw different user profiles with more or less influence over the database content.
System privileges have to be associated with object permissions to evaluate the rights of a user, group, or role. For example, if a user has the modify privilege, he cannot modify an object on which he has no update permission.
Terminology
In some DBMS, system privileges are called permissions. In this manual, the term privilege is used for any right granted to a user, a group, or a role. Permissions are defined for objects.
