About This Architecture

Hospital entity relationship diagram modeling core healthcare data structures including Patient, Doctor, Appointment, Department, Room, Medical Record, Prescription, Medication, and Bill entities. The schema captures patient scheduling flows where patients schedule appointments attended by doctors, while doctors write prescriptions containing medications and medical records generate bills. Cardinality notations (1:N relationships) illustrate how one patient can have multiple medical records and appointments, essential for HIPAA-compliant database normalization. Healthcare developers can fork this ERD on Diagrams.so to customize entity attributes or extend with Insurance and Lab Result tables. Primary keys (patient_id, doctor_id) and attributes like specialty and dob provide a foundation for relational database implementation.
