Based on the case below, draw an ERD using Chen’s notation with cardinality and participation.
Nirmala Gandhi is the HR manager at Felix Partners (FP), a law firm. She asked you to design a database to manage FP’s employees, who are classified as either staff, managers, or partners. Each employee has a unique 4-digit employee ID. FP wants to record full name (first name, MI, last name), phone numbers, home address, and email addresses. FP also wants to keep track of who is the supervisor of an employee.
