Develop an EER model for the following situation, using the traditional EER notation, the Visio notation, or the subtypes inside supertypes notation, as specified by your instructor: A technology company provides offerings to its customers. Offerings are of two separate types: products and services. Offerings are identiļ¬ed by an offering ID and an attribute of description. In addition, products are described by product name, standard price, and date of ļ¬rst release; services are described by name of the companyās unit responsible for the service and conditions of service. There are repair, maintenance, and other types of services. A repair service has a cost and is the repair of some product; a maintenance service has an hourly rate. Fortunately, some products never require repair. However, there are many potential repair services for a product. A customer may purchase an offering, and the company needs to keep track of when the offering was purchased and the contact person for that offering with the customer. Unfortunately, not all offerings are purchased. Customers are identiļ¬ed by customer ID and have descriptive data of name, address, and phone number. When a service is performed, that service is billed to some customer. Because some customers purchase offerings for their clients, a customer may be billed for services he or she did not purchase, as well as for ones that were purchased. When a customer is billed for a service (although some may never require a service of any type), the company needs to keep track of the date the service was performed, the date the bill is due, and the amount due.
