For example, the interaction (or dialog) of someone accessing an ATM would look as follows:Use case name: Authenticate user1. ATM displays welcome message to Customer2. ATM asks user to insert card3. Customer inserts card into ATM4. ATM asks user to enter their PIN5. Customer enters their PIN6. ATM authenticates the customer using the information from the card and the PINA use case is functional and outlines the behavior of a set of interactions that form a coherent dialog in the system, i.e. Authenticate user. This interaction is separate and distinct from the use case Withdraw money, which also involves a series of interactions.Use Case DiagramA use case diagram shows the relationship between the actors and the use cases.
