Please explain the relationships, assumptions (if any), and the rationale for the choices. Case Study: Hospital Management Description: A new hospital is seeing an increase in the number of their patients. They want to create a software system that manage their employees and patients. A part of their software requirement is given below. You also are required to do a self-study on how the out-patient departments of hospitals function and create/develop a system for managing the department. Requirements: The people in the clinic are either staff members or patients. The hospital works in three shifts, each of 8 hours. The first shift starts at 7 am and staff members are required to punch-in. All staff members work only in one shift. The staff members are either Administrative Staff, Operations Staff, or Technical Staff. A patient first approaches the front desk and registers to see a doctor based on availability and the receptionist issues a number to the patient to wait in queue. A patient is then met by the Operations staff, i.e. the doctors, surgeons, or nurses. Based on the outcome of the consultation the patient goes to front desk to finalize the payment of their visit and exits the system. The hospital also has Technical Staff, who are the surgical technologists that deal with surgical equipment and technicians that manage other office equipment. All relevant details like IDs, names, salaries, addresses, and phone numbers, of the patients and staff members are stored in the hospital system. At any point in time, the system is able to generate reports to show the details of staff members that are on a particular shift, the number of patients that are in queue, and the number of patients or technical issues handled by each staff member
