Interaction Overview Diagram
The Interaction Overview Diagram is new in UML 2.0/2.1. However, it is merely a mixture of an activity diagram and a sequence diagram, whereby activity blocks can be mixed into a sequence diagram and vice versa.
As it does not contain any other new features, it will not be discussed in detail here.
Fig. 58: Sample Interaction Overview Diagram
The example here shows the ‘Make transfer’ process, whereby the main diagram is an activity diagram and an action (save order) is described in more detail by a sequence diagram.
