Use case diagrams and activity diagrams are behavioral UML diagrams that describe the dynamic characteristics of a system. The difference between use case diagrams and activity diagrams is that use case diagrams help to model the system, user interactions, while activity diagrams help to model the workflow of the system and are often used to illustrate the internal logic of use cases. These diagrams offer multiple advantages. They help model business requirements and understand the functionality of the system at a high level.

Use cases describe how users use the system to achieve specific goals. A use-case diagram consists of a system, related use cases, and actors, and relates them to each other to visualize: What is it describing? (System), who is using the system? What are the actors trying to achieve? Thus, use cases help ensure that the right system is developed by capturing requirements from the user’s point of view.
