university has several types of employees: Full Time Faculty, Part Time Faculty, Full Time Support Staff, Part Time Support Staff, and Management/ Non Union Staff. For each type of employee, we store the first and last name, the employee ID. For all Faculty, we store the courses the Departments where they teach. For all Staff we store their Title or Roles. Every employee must be a member of one of these types. Using generalization, develop a portion of an ER diagram that represents the situation. Remember to include a subtype discriminator
