Detailed explanation-1: -What is the purpose of an activity diagram? An activity diagram describes the various user (or system) activities, the person who does each activity, and the sequential flow of these activities. Explain why the Unified Modeling Language (UML) is important to use as a standard for creating information systems models.
Detailed explanation-2: -An activity diagram shows business and software processes as a progression of actions. These actions can be carried out by people, software components or computers. Activity diagrams are used to describe business processes and use cases as well as to document the implementation of system processes.
Detailed explanation-3: -An activity diagram visually presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram. Activity diagrams are often used in business process modeling. They can also describe the steps in a use case diagram. Activities modeled can be sequential and concurrent.
Detailed explanation-4: -Activity diagram is basically a flowchart to represent the flow from one activity to another activity. The activity can be described as an operation of the system.
Detailed explanation-5: -The UML activity diagram shows the dynamic behavior of software and the sequence diagram plays an important role to construct an activity diagram which in turn uses scenarios and uses case as an input. To Model business and in the development of software systems the activity diagram is used.
