Consider the following problem description: Consider an online reservation system for a bus company. The bus company includes several buses and realizes trips to different cities. Each bus is identified by its plate number and a separately assigned bus number. The trips are based on a predefined schedule and stop at predefined bus stations. Each bus can have only one trip per day. Each bus includes a driver and one hostess. For long trips, the bus will have breaks at service and rest areas. 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 website of the bus 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 bus company). If the customer has not paid for the seat, the bus 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. From the above description: (a) Draw a Use-Case Diagram for describing the functional requirements of the above system. (b) Decide TWO (2) non-functional requirements that could be important for the above system. (c) Perform an analysis object (i.e., domain) modelling (class diagram) for the software system described above. You need to identify the attributes only for the Seat and Bus and do not need to identify the operations of objects. You may simply show the resulting model without showing the individual steps.
