Assignment:
You need a Use Case Diagram for this since I am stuck on about the verification of ACRS account:
My Primary Actors (LEFT) are: Customer, Clerk, Store Manager
Secondary Actors (RIGHT): Store System
A Car Rental Store (ACRS) runs a series of fairly small car rental stores. Before a car can be put up for rent, it must be assessed and entered into the system. Every customer must have a valid ACRS account in order to rent a car. Customers rent cars for up to five days at a time. Every time a customer rents a car, the system must ensure that they have a valid driver license. If they don they are not able to rent a car. The system must ensure that the customer has a valid ACRS account with no overdue balance. If there is no account, the customer must create one. If there is an overdue balance, that balance must be paid before the customer can rent a car. When the car is returned, the clerk checks for a full tank of gas. If the tank is not full, the customer is charged a fee. Every morning, the store manager prints a report that lists cars rented and highlights those that will be returned that day. The manager calls those customers to see if they would like to extend their rental. If a car is returned in damaged condition, the manager removes it from the system and charges the customer.
