Use Case Diagram

A UML use case diagram for the interaction of a client (the actor) within a restaurant (the system)

A use case diagram at its simplest is a representation of a user's interaction with the system that shows the relationship between the user and the different use cases in which the user is involved. A use case diagram can identify the different types of users of a system and the different use cases and will often be accompanied by other types of diagrams as well.
