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 include an E-R diagram, a set of relational schemas,
and a list of constraints, including primary-key and foreign-key constraints.
