Question

List the type of objects that have changing state (Ex, Movie (available, reserved, rented))

CC Video store rents movies. You are testing the IT system that maintains the inventory of movies, customers, rentals and reservations.

CC Video rents movies by the day, for a fee of $5. All rentals are for one day and the customer pays before taking the movie out of the shop.

Returns are due by 6 pm on the next day. Customers return movies by handing the rented copy to staff or dropping it into in a return box. The late fee is $6.00 for every day or part day overdue. Except for high demand movies, the store usually waves the fee for returns just a few hours late.

All customers are members. Joining is free, but involves showing ID. The IT system assigns a member number and then uses member number together with last name and phone number to verify identity. All members in good standing (with no unpaid fines) can rent movies.

Members can also reserve movies to be picked after 6 pm on the same day. The store must keep enough copies on reserve to satisfy all reservations.
