Interaction Overview Diagram

Interaction Overview diagrams visualize the cooperation between other interaction diagrams to illustrate a control flow serving an encompassing purpose. As Interaction Overview diagrams are a variant of Activity diagrams, most of the diagram notation is the same, as is the process of constructing the diagram.

Decision points, Forks, Joins, Start points and End points are the same. Instead of Activity elements, however, rectangular elements are used. There are two types of these elements:

•	Interaction elements display an inline Interaction diagram, which can be any one of the four types (Sequence, Timing, Communication or Interaction Overview)

•	Interaction Occurrence elements are references to an existing Interaction diagram: they are visually represented by a frame, with ref in the frame's title space; the diagram name is indicated in the frame contents

To create an Interaction Occurrence, simply drag an Interaction diagram from the Project Browser onto your Interaction Overview diagram. The ref frame displays, encapsulating an instance of the Interaction diagram.
