Draw a class diagram for the following situation about a car service system that keeps car service records: When a vehicle is serviced by a dealer a service record is entered to the system and it should contain information about service date and current mileage. Vehicles are serviced many times at various dealers, which service many vehicles. Each dealer is specialized with certain manufacturer of vehicles. Owner and vehicle are entered to the system only when an owned vehicle is first serviced by a dealer. Owner information such as name and address are recorded, while VIN, model, and model year are recorded for vehicles. There are two types of vehicles, cars and trucks: car has additional attributes for the number of doors and luxury level and truck has an additional attribute of cargo capacity. Each service record is associated with a predefined service type and each service type may use multiple parts.
