A technology company provides offerings to its customers. Offerings are of two separate types:

products and services. Offerings are identified by an offering ID and an attribute of description.

In addition, products are described by product name, standard price, and date of first release;

services are described by name of the companys 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 identified 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.
