Activity Diagram

Activity diagrams are used to model the behaviors of a system, and the way in which these behaviors are related in an overall flow of the system. The logical paths a process follows, based on various conditions, concurrent processing, data access, interruptions and other logical.

Use to:

  • Model system behavior
  • Model dynamic element interactions
