Quizplus · Accepted Answer

In an ER diagram, attributes like DriverName are not typically enforced as unique unless explicitly stated, usually through a unique constraint or by being a primary key. Without specific information stating that DriverName is unique, we cannot assume it to be true, especially considering that names are not commonly used as unique identifiers due to the possibility of duplicates.
