This document outlines a proposed hospital management system through three levels of data flow diagrams (DFDs). The level 0 DFD shows the system managing patient and doctor information, registering cases, prescribing medicines and suggestions. The level 1 DFD breaks this down into five main processes: patients can specify symptoms, view diseases, manage prescriptions/tests, doctors can process bills, and the admin can maintain the system. The level 2 DFD further separates the maintenance process into modifying medicines/diseases details and doctor/patient details.
