Answer to Question 1

UML-style E-R diagrams draw an entity as a vertical rectangle with three segments. The top segment shows the name of the entity, entity persistence and class attributes (if any). The second segment holds the entity attribute names, and the third segment documents OOP constraints and methods that belong to the entity. Public, Protected, Private attributes and methods are preceded by +., -, respectively.
