- Develop an entity-relationship model for the following scenario. A piano manufacturer wants to keep track of all the pianos it makes individually. Each piano has an identifying serial number and a manufacturing completion date. The manufacturer has piano technicians who are responsible for inspecting the instruments before they are shipped to the customers. Each piano is inspected by one or more technicians (identified by their employee number). For each separate inspection, the company needs to record its date and a quality evaluation grade.arrow_forwardHello, Just want to check if the attached Crow's Foot ERD is correct for the following problem: Given the information below, create the fully labeled Crow's Foot ERD using a specialization hierarchy where appropriate (use Visio).
