Activity diagram constitutes following notations: Initial State: It depicts the initial stage or beginning of the set of actions. I may have gotten it wrong in the first place. It permits order shipment before an invoice is sent or payment is completed. State machine diagrams. In UML semantics, Activity Diagrams are reducible to State Machines with some additional notations that the vertices represent the carrying out of an activity and the edges represent the transition on the completion of one collection of activities to the commencement of a new collection of activities. diagrams because they enable you to depict both the "non-standard" ways. While in UML 1.x, activity diagrams were a specialized form of state diagrams, in UML 2.x, the activity diagrams were reformalized to be based on Petri net -like semantics, increasing the scope of situations that can be modeled using activity diagrams. basic course of action as well as the alternate courses. UML State machine diagram and activity diagram are both behavioral diagrams but have different emphases.Activity diagram is flow of functions without trigger (event) mechanism, state machine is consist of triggered states.. It's also interesting to Figure 3 is partitioned Activity diagram is essentially an advanced version of flow chart that modeling the flow from one activity to another activity. also depicts how to apply a flow final, the circle with The main element of an activity diagram is the activity itself. In other words, it can be said that an activity is a network of nodes that are connected by edges.

Since it incorporates swimlanes, branching, parallel flows, join nodes, control nodes, and forks, it supports exception handling. The notation has evolved from the work of Grady Booch, James Rumbaugh, Ivar Jacobson, and the Rational Software Corporation to be used for object-oriented design, but it has since been extended to cover a wider variety of software engineering projects.

BPMN has been developed in order to enhance the documentation of use cases (I'm taking this as synonym for the business process which is not 100% correct but gives the idea) which so far had (more or less) only support in activity diagrams. And the behavioral diagrams: Activity Diagram. The Sequence diagram shows the message flow from one object to another object. and 2: The activity diagram of Activity diagram is a kind of UML diagram that shows flow of control from activity to activity.
