I have been asked to create a computer application, either programmed or using a database, to replace the current manual record-keeping system.

The next time the company books in a recorded car for new tyres, Tod checks the cars file to see what type of tyre that car has fitted; he then ensures hat he has the required tyres in stock: "PRICELISTTBL" (type of tyres), (manufacturers code) and (customer's price ex VAT).
