Question

Draw a sequence diagram for seat reservation use case.

You are to develop an online reservation system for a train company. The train company includes
several trains and realizes trips to different cities. Each train is identified by a plate number and a
separately assigned train number. The trips are based on a predefined schedule and stop at
predefined train stations. Each train can have only one trip per day. Each train includes two
conductors, a number of waiters and other personnel. For long trips, the train will stop at
intermediate stations. There are two types of trips, normal trips and express trips. Express trips do
not stop at intermediate stations and get faster at the destination.
Seats can be reserved by customers on the web site of the train company. The customer has the
option to directly pay for the seat through the website. In that case, the seat cannot be cancelled
(neither by the customer nor by the company). If the customer has not paid for the seat, the train
company can cancel the seat if the customer does not show up one hour before the trip. When the
reservation is cancelled, the seat will become free and can be sold to another customer. Both the
customer and the company staff must authenticate themselves for performing operations with the
system. The application should be able to run both in web and as an android application which
require different views.
