Interaction Overview Diagram is one of the fourteen types of diagrams of the Unified Modeling Language (UML), which can picture a control flow with nodes that can contain interaction diagrams. Interaction overview diagrams provide a high level of abstraction a model similar to activity diagrams, but also show the interactions between other interaction diagrams. An interaction overview diagram can show normal or alternative control flow within a system. The interaction overview diagram notation is similar to the notation for activity and sequence diagram. An interaction overview can also show the flow of activity between diagrams. In other words, you can link up the “real” diagrams and achieve high degree navigability between diagrams inside an Interaction Overview Diagram.
