Use DIA to create ONLY the Entity Relationship Diagrams (ERD) for the following question.

QuickLube is in the quick oil and lube business. Although customers bring in their cars for service such as oil change. QuickLube also replaces windshield wipers, oil filters, and air filters, subject to customer approval. The ERD should contain information about each customer, his/her car, date of service, grade and amount of oil used, parts replaced, and of course, total amount due.

- Information about a car includes plate#, make, model, and year

- Each car is owned by one customer, each customer may have more than one car.

- Each part(whindshield wippers, oil filters, or air filters, etc.) has a unique part number. Each part has a part cost and labor cost.

- Different grade of oils are available. A grade of oil has a grade name(A,B,C etc) and a price/qt.

(This problem was already posted elsewhere on here, but the answer they gave left me really confused about several things, so I'm posting it again).
