A small used car lot would like to develop a database to track their vehicle inventory. You have been asked to create an ER Diagram to begin
the database modelling process. The Entities required should include, but are not limited to:
Vehicles this entity holds information about a specific vehicle, such as its VIN number, mileage, date of manufacture
Manufacturers data examples: Ford, GM Acura, Honda, etc
Models data examples: Accord, Camry, Focus, etc
Options this entity holds information about optional features such as air conditioning, moon roof, heated seats, alloy wheels
Some key relationships are as follows:
One Manufacturer can manufacture zero, one or many Models
One Model can have zero, one or many Vehicles
One Vehicle can have zero, one or many Vehicle Optons
Complete an ER Diagram for this model making sure you clearly identify each entity and the relationships between each entity including cardinality.
Your final diagram should resolve any associative entities you identify ie the final diagram shall not contain any manytomany relationships
