Our used car lot only sells cars that we finance. Every car that we sell must also have insurance and a title before it rolls off the lot. We want to capture the date that we sell the car and the amount paid. Cars have a unique VIN, a make, a model, a color and a sticker price. Not every car has been sold. Insurance has an INSID, a policy date and a coverage amount. Insurance policies are only created at the time of the car purchase so every policy is attached to a car. Loans have a LoanID, interest rate, issue date and amount. Loans are also issued at the time of purchase so all loans are assigned to a car purchase event.
