Activity diagrams deal with all type of flow control by using different elements such as fork, join, etc.Other four diagrams are used to show the message flow from one object to another but activity diagram is used to show message flow from one activity to another.
Activity diagrams are not only used for visualizing the dynamic nature of a system, but they are also used to construct the executable system by using forward and reverse engineering techniques. It shows different flows such as parallel, branched, concurrent, and single. Activity diagrams are not exactly flowcharts as they have some additional capabilities. ![]() The main element of an activity diagram is the activity itself. After identifying the activities, we need to understand how they are associated with constraints and conditions. This mental layout is then transformed into an activity diagram. In the diagram, four activities are identified which are associated with conditions. One important point should be clearly understood that an activity diagram cannot be exactly matched with the code. The activity diagram is made to understand the flow of activities and is mainly used by the business users. After the type of order is identified, dispatch activity is performed and that is marked as the termination of the process. This specific usage is not available in other diagrams. These systems can be database, external queues, or any other system. From the above discussion, it is clear that an activity diagram is drawn from a very high level. This high level view is mainly for business users or any other person who is not a technical person. The diagram has more impact on business understanding rather than on implementation details.
