Develop a Use case diagram based on the following narrative. Note any ambiguities that

you have as you develop the model. If you need to make assumptions, also note them.

Consider an online reservation system for a bus company. Seats can be reserved by

customers on the website of the bus company. While reserving a seat, the system displays the

available seats, so the customer can reserve the suitable seats. The customer has the option to

directly pay for the seat through the website using credit card. The system should validate the

credit card before completing the payment. After the payment is completed, the customer can

print the ticket. Also, he can cancel the reservation of a seat at any time.

If the customer does not pay online for the seat and does not show up one hour before the

trip, the bus company can cancel the seat.UnidentifiedUnidentified
