Background
We want to keep track of the price we charge for each type of part, the supplier for each type of part, and the amount we pay the supplier for each type of part (the cost). Each supplier can provide us with many different types of parts, but each part can be provided to us by only one supplier. This requires a one-to-many relationship.
Functional analysis:
Part —- > Price, Cost, Supplier, Street, City, State, Zip, Telephone
Supplier —- > Street, City, State, Zip, Telephone
Part —- > Price, Cost, Supplier
Table:
Parts (Part, Price, Cost, Supplier, Street, City, State, Zip, Telephone)
