The entity a plays a specific role (``Role-name'') in the ``W-concept''. The concept ``P-concept'' has a semicircle on the right sides. It means the concept is defined in other schema. The ``L-concept'' is a specification of the ``U-concept'', and the ``U-concept'' is a generalization of the ``L-concept''.
