About the framework
Connect appointments and records to patients and doctors
The hospital ER example contains PATIENT, DOCTOR, DEPARTMENT, APPOINTMENT, and MEDICAL_RECORD. Appointments reference both a patient and a doctor, with a scheduled time, status, and notes. Medical records reference the same two entities and include a date, diagnosis, treatment, and prescription text.
Five relationships are drawn. The diagram links doctors to a department, but the Doctor attribute list has no department_id foreign key. Department includes floor and bed_count; there are no separate bed, admission, medication, or billing entities. The illustrated relationship therefore needs further schema detail before implementation.
Use the model to review the scope of a scheduling and records application. Request the missing department key and decide which concepts require their own tables. A diagram can document those choices, while database constraints and access rules still need separate implementation.

Frequently asked questions
Common questions
Is the Doctor-to-Department relationship fully specified?
The relationship is drawn, but Doctor has no department_id field. Add the foreign key or revise the relationship model before implementing it.
Does this model hospital admissions?
No. It covers appointments and medical records. Department has a bed_count attribute, but there are no admission, individual bed, or bed-assignment entities.
How are prescriptions represented?
Prescription is a string on Medical Record. If your application needs multiple medication entries per record, request separate entities and define their fields and relationships.
