Given the following business scenario, create a Crow’s Foot ERD using a specialization
hierarchy if appropriate. Tiny Hospital keeps information on patients and
hospital rooms. The system assigns each patient a patient ID number. In addition,
the patient’s name and date of birth are recorded. Some patients are resident patients
who spend at least one night in the hospital, and others are outpatients who are
treated and released. Resident patients are assigned to a room. Each room is identified
by a room number. The system also stores the room type (private or semiprivate)
and room fee. Over time, each room will have many patients. Each resident
patient will stay in only one room. Every room must have had a patient, and every
resident patient must have a room.
