Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate for one case study. 1. Two-Bit Drilling Company holds information about employees and their insurance dependents. Every employee has an employee number, name, date of hire, and title. If an employee is an inspector, then the date of certification and the renewal date for that certification should also be recorded in the system. For all employees, the Social Security number and dependent names should be kept. All dependents must be connected with one and only one employee. Some employees will not have dependents, while others will have many dependents
