Non programmers use Flow charts to model workflows. Activity diagram is good at depicting the control flowing from one activity to another, especially good at the logic of conditional structures, loops, concurrency. Arrange these circles in a vertical line if you can, although this isn’t critical. Initial node is a control node at which flow starts when the activity is invoked.. A control token is placed at the initial node when the activity starts, but not in initial nodes in structured nodes contained by the activity. Activity Diagrams consist of activities, states and transitions between activities and states which describe how activities are coordinated to provide a service, such as, how the events in a single use case relate to one another, or how a collection of use cases coordinate to create a … Purists of the object-oriented approach probably dislike this fact. An activity represents an operation on some class in the system that results in a change in the state of the system. The rest is pretty straightforward.
