Consider a vehicle purchasing software system that allows a customer to buy cars, buy motorbikes, and buy trucks. As all of the above are vehicles, there is a fourth functionality called buy vehicles whose purpose is to provide all the common functions in buying any type of vehicles. This last functionality, i.e. functionality (iv), is performed automatically by the software system and does not require any interaction with the customer.

Transcribed Image Text:Consider a vehicle purchasing software system that allows a customer to
buy cars,
buy motorbikes, and
buy trucks.
As all of the above are vehicles, there is a fourth functionality called
buy vehicles
whose purpose is to provide all the common functions in buying any type of vehicles. This
last functionality, i.e. functionality (iv), is performed automatically by the software system
and does not require any interaction with the customer.
Draw the Use-Case diagram, including all actors and the relationships between all
use cases.
Suppose that the above vehicle purchasing software system has objects of the
following classes:
Vehicle this is an abstract class with all the common attributes and operations
of the different types of vehicles.
Car this is a concrete class referring to a particular type of vehicle
Motorbike - this is a concrete class referring to a particular type of vehicle
Truck - this is a concrete class referring to a particular type of vehicle
A customer can own any number of cars, motorbikes or trucks, but not vehicles.
There are no real objects called vehicles. Draw the Class diagram including all
relationships, associations and multiplicities between the classes and the customer.
