But in the Login use case there is only one actor - the Employee.
In the case of DB administration the actor is the DBA.
The fact that the DBA is also an employee is irrelevant to the
administration use cases. In fact, in the future this may not be the case.
The DBA may no longer be an employee. Your DB administration use cases
don't need to change just because your DBA is a contractor.
Similarly, if your DBA your manager and your programmer are the same person
is irrelevant. It's the hat that the person is wearing that determines what
actor that person is.

Please respond to
"Zhuang, Hong"
It depends on how each role interacts with the system. In the login use
case, for instance, the process is the same regardless of which role the
actor play. You therefore present this use case as if the actor has one
role, but use a note to indicate that the actor has many roles.
Hope it helps
