1. Design, on paper, using an entity-relationship format, a database for an organization with 50 customers, 6 products, 2 telephone sales reps, and 2 suppliers. Sales reps write sales orders for customers. Sales orders must be able to have more than one product on an order. Suppliers provide products in response to purchase orders which may be for one or more than one product. Add transaction tables as necessary. All of the entities must be normalized within the diagram. The diagram should identify appropriate fields (no more than 5 per entity class) depicting the proper primary-key/foreign-key relationship and data types. No data is required.
