To create an initial entity-relationship diagram (ERD) for the New Century Health Clinic system, key entities might include Patient, Doctor, Appointment, and Treatment. The Patient entity would have attributes like Patient_ID, Name, and Contact_Info, while the Doctor entity would include Doctor_ID, Name, and Specialization. The Appointment entity would link Patients and Doctors, with attributes such as Appointment_ID, Date, and Time. Finally, the Treatment entity could relate to both Patients and Appointments, detailing Treatment_ID, Description, and Cost, establishing relationships among these entities.
