Summary

Use case diagrams are UML diagrams used to describe the different ways a user can interact with a system. They are represented with an oval shape, actors, and a line between the actor and use case. Use cases specify the expected behavior of a system, but not the exact method of making it happen. They are used to summarize the details of a system's users and their interactions with the system. 1 2
