Design a database for an automobile company to provide to its dealers to assist
them in maintaining customer records and dealer inventory and to assist sales staff in
ordering cars.
Each vehicle is identified by a vehicle identification number (VIN). Each
individual vehicle is a particular model of a particular brand offered by the company
(e.g., the XF is a model of the car brand Jaguar of Tata Motors). Each model can be
offered with a variety of options, but an individual car may have only some (or none)
of the available options. The database needs to store information about models, brands,
and options, as well as information about individual dealers, customers, and cars. Your design should includen an E-R Diagram, a set of relational schemas and a list of constraints including primary key and foreign key constraints
