Two: The relationship between several graphs

1, the difference between the activity diagram and the state diagram

Activity diagrams focus on the behavior of the action to describe the state diagram focusing on the behavior of the results to describe

2, the difference between the activity diagram and the flowchart

(1) The activity diagram describes the sequence relation rules of the object's activities, and emphasizes the behavior of the system.
