Question Specifications: A friend of yours is opening the Professional Electronics and Repairs shop to repair smartphones, laptops, tablets, and other smart devices. She wants you to create a database to help her run her business. Create a Crow's Foot notation ERD to support the following business operations: When a customer brings a device to PEAR for repair, data must be recorded about the customer, the device, and the repair. The customer's name, address, and contact phone numbers must be recorded (if the customer has used the shop before, the information already in the system for the customer is verified as being current). For the device to be repaired, the type of device, model, and serial number are recorded (or verified if the device is already in the system). Only customers who have brought devices into the shop for repair will be included in this system. Since a customer might sell an older device to somcone else who then brings the device to the shop for repair, it is possible for a device to be brought in for repair by more than one customer. However, each repair is associated with only one customer. When a customer brings in a device to be fixed, it is referred to as a repair request, or just "repair," for short. Each repair request is given a reference number, which is recorded in the system along with the date of the request, and a description of the problem(s) that the customer wants fixed. It is possible for a device to be brought to thoe shop for repair many different times, and only devices that are brought in for repair are recorded in the system. Each repair request is for the repair of one or more devices. There are a limited number of repair services that the shop can perform. For each repair service, there is a service ID number, description, time required, rate, and charge. "Charge" is how much the customer is charged for the shop to perform the service and is calculated by the time required times rate, plus costs of parts required for the service. The actual repair of a device is the performance of the services that were required to to address the problems described by the customer. Completing a repair request may require the performance of many services. Each service can be performed many different times during the repair of different devices, but each service will be performed only once during a given repair request. Any repair eventually requires the performance of at least one service, but which services will be required may not be known at the time the repair request is Some services involve only labor activities and no parts are required, but most services require the replacement of one or more parts. How many of cach part are required for a specific service is specified when the service is entered into the system. For cach part, the part number, part description, quantity in stock, and cost per unit is recorded in the system. Some parts may be used in more than one serviceStep by Step Solution
