Each User is linked to one Patient, and a Patient can book multiple appointments, establishing a one-to-many relationship. The Doctor entity tracks doctor information and their appointments, while the Availability entity defines the time slots for each doctor. Importantly, each appointment uses one availability slot, creating a one-to-one relationship. Please review the diagram and let me know if you have any questions or feedback."}
