Consider the following automotive enterprises, involving cars, car manufacturers, and car dealerships. Car Manufacturers are companies that build cars and they have attributes such as name, headquarters address, country of incorporation, etc. Cars have attributes such as make (e.g., Ford, Volkswagen, Chrysler), model number, kind of car (e.g., sedan, SUV, wagon), etc. A dealership sells cars. It
has a name, address, and telephone numbers (typically more than one.) A manufacturer may make several di erent kinds and models of cars (as, for example, the manufacturer Mercedes/Chrysler does). A car is made by a single manufacturer. A dealer can sell cars from several di erent manufacturers but does not have to sell all the cars from a single manufacturer. For example, Nardy Honda-Pontiac in Smithtown sells Pontiacs from manufacturer GM and Hondas from manufacturer Honda, but it doesn't sell Chevrolets that are also made by GM. A manufacturer can make a car (such as a racing car) that is not sold through dealerships. Represent the above as an E-R diagram; include all relevant constraints.
