Sequence Diagram
In Rational Software Architect's Model Explorer view, right-click Phone Book UML Model and select Add Diagram > Sequence Diagram.
Replace the default name SequenceDiagram1.
Drag the actor “User” from the Model Explorer view to the diagram to create an instance of the actor.
Similarly Drag the following in the sequence canvas:
PhoneBookView
PhoneBookController
PhoneBook Model
