A collaboration diagram, also called a communication diagram or interaction diagram, is an illustration of the relationships and interactions among software objects in the Unified Modeling Language (UML). The concept is more than a decade old although it has been refined as modeling paradigms have evolved.
So the solution is to use different types of models to capture the different aspects of the interaction. That is why sequence and collaboration diagrams are used to capture dynamic nature but from a different angle. So the purposes of interaction diagram can be describes as: To capture dynamic behaviour of a system. To describe the message flow in the system. To describe structural organization of the objects.
