    I took an example ERD, but ask if what I found in it, is a flaw

      I took an example ERD image used as a reference,it's a class diagram modeling a simple entities relationship for a supermarket pay database.
      I ask if what I found in it there is a flaw. You can find the diagrams, with the one amended from me put beside HERE [http://www.orafaq.com/forum/fa/10013/147115/], with indication of what I think is a flaw.
      One more point: if I'm interested in tracking shifts worked over time in the shifts table, I'm still able to do so.

      Any comment would be appreciated.
