ERD Assignment
Create an ERD for a car dealership. Make sure to mark each of your table's relationships specifically with PK for Primary Key and FK for Foreign Key. Connect the PK and FK relationships accordingly. BACKGROUND: The dealership sells both new and used cars, and it operates a service facility. Base your design on the following business rules:
• A salesperson may sell many cars, but each car is sold by only one salesperson.
• A customer may buy many cars, but each car is bought by only one customer.
• A salesperson writes a single invoice for each car he or she sells.
• A customer gets an invoice for each car he or she buys.
• A customer may come in just to have his or her car serviced; that is, a customer need not buy a car to be classified as a customer.
• When a customer takes one or more cars in for repair or service, one service ticket is written for each car.
• The car dealership maintains a service history for each of the cars serviced. The service records are referenced by the car's serial number.
• A car brought in for service can be worked on by many mechanics, and each mechanic may work on many cars.
• A car that is serviced may or may not need parts (e.g., adjusting a carburetor or cleaning a fuel injector nozzle does not require providing new parts). DELIVERABLE: Your end product is to submit a single page ERD depicting the full model of the car dealership relational database.
