3.6. Interaction Diagrams

This section discusses a dynamic diagram form that represents interaction among selected elements (see Figure 3.136). The best-known candidate of interaction diagrams is the sequence diagram. In addition, there is the communication diagram, which was called “collaboration diagram” in UML 1.x, and there are two new diagram forms introduced in UML 2: the timing diagram and the interaction overview diagram.
