It supports flow branches via the decision elements and the merge elements and parallel execution using forks. OMG is continuously making efforts to create a truly industry standard. We describe or depict what causes a particular event using an activity diagram. Intermediate event symbol … An activity is the specification of a parameterized sequence of behaviour. The key difference between use case diagram and activity diagram is that the use case diagram helps to model the system and user interactions while the activity diagram helps to model the workflow of the system.. UML stands for Unified Modelling Language. An activity … It supports flow branches via the decision elements and the merge elements and parallel execution using forks. 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. Copyright © 2020 All Rights Reserved - Meera Academy. For an activity diagram, you’ll want to begin by dragging out the start node—a black circle—from the toolbox.
