The following sections describe additional EA specific Interaction Overview diagram information.
Interaction Overview Diagram
An Interaction Overview diagram is one of four types of Interaction diagrams. The other three are Timing, Sequence, and Communication diagrams. An Interaction Overview diagram, just like an Activity diagram, visualizes a sequence of activities. Most of the notation elements for Interaction Overview diagrams are the same as those for Activity diagrams (such as Initial, Decision, Fork, Join, and Final Nodes). Interaction Occurrences and Interaction elements are two new elements in the interaction overview diagrams.

Interaction Element
Interaction elements display an inline Interaction diagram (Interaction Overview, Timing, Sequence, or Communication diagram). In EA, Interaction elements can be created to display other diagrams than those classified as Interaction diagrams.

Interaction Occurrence
Interaction Occurrence elements refer to an existing Interaction diagram. They are visually represented by a rectangular frame, which can be created by dragging the Interaction diagram from the project Browser to an Interaction Overview diagram and selecting the Interaction Occurrence command from the shortcut menu.
