Question 7 On ERD, you can create attributes with the same name in different Entities. Question 7 options: True False
Create a Crow’s Foot notation ERD to support the following business operations: A friend of yours has opened Professional Electronics and Repairs (PEAR) to repair smartphones, laptops, tablets, and MP3 players. She wants you to create a database to help her run her business.   When a customer brings a device to PEAR for repair, data must be recorded about the customer, the device, and the repair.

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 PEAR for repair will be included in this system.   Since a customer might sell an older device to someone else who then brings the device to PEAR for repair, it is possible for a device to be brought in for…
