Following is an example of an activity diagram for order management system. 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 ...
The Activity Diagram can help to describe the flow of control of the target system, such as the exploring complex business rules and operations, describing the use case also the business process.

Use a Decision shape with guard conditions to indicate a possible transition from an action state. Use the Fork node to represent the forking of one action state into multiple parallel states. Use the Join node to represent the synchronization of multiple action states into one state.See...
Formal methodsThe UML Activity Diagram (UAD) is mostly used for modeling behavioral aspects of objects and systems. OCL (Object Constraint Language) is used together with UAD to specify guard conditions and action constraints. Due to the ambiguous semantics of UAD, it is relevant to formalize ...
