Exercise 3: Hospital Management System Develop a Data Flow Diagram (DFD) for a Hospital Management System. In this system, Patients can register for services, schedule appointments with Doctors, and make payments. Doctors can access patient records, update medical information, and manage their appointment schedules. The Reception desk is responsible for processing patient registrations and handling payments. The system also integrates with the Pharmacy, where patients can obtain prescribed medications. Create a Level 0 and Level 1 DFD to represent the flow of data between the various entities involved in the hospital management process.
