Question

Railway Reservation System is a system used for booking railway tickets over the Internet. Any Customer can book tickets for different trains. The Customer can book a ticket only if it is available. Thus, he first checks the availability of tickets, and then if the tickets are available he books the tickets after filling details in a form. The Customer can print the form when booking a ticket. Note that to book a ticket the customer has to checkout by paying fare amount.
Booking tickets can be in two ways: by i-ticket or by e-ticket booking. In case of i-ticket booking, the Customer can book the ticket online and a Clerk prints the ticket then the ticket is couriered to the Customer at his address. But in case of e-ticket booking, tickets are booked online, sitting at the home, and the Customer himself has to print the ticket.
For cancellation of ticket, the Customer has to go to a reservation office to fill a cancellation form and ask the Clerk to cancel the ticket. Ticket cancellation includes refunding money to customer account.
