Activity Diagram

Activity diagrams are used to model system behaviors, and the way in which these behaviors are related in an overall flow of the system (that is, dynamic element interactions). The logical paths a process follows, based on various conditions, concurrent processing, data access, interruptions and other logical path distinctions, are all used to construct a process, system or procedure.
