Create a conceptual model based on the following information:
1.A database for a local garage is needed. The database contains data items for a customer account number, the customers name, the customers address, the customers work telephone number, the customers home telephone number, date of work done, automobile make, automobile model, description of work done, parts needed to complete the work, charge for parts needed, and charge for labor performed. For warranty reasons, data must be maintained in the database for at least ninety days; therefore, a customer may have several records in the database at any particular time. Identical parts have only one cost, but different parts have different costs (for example, all tires cost the same and all engines cost the same, but a tire and an engine do not cost the same). A customer may have more than one car. Draw the ER diagram to model these data relationships.
