inheritance$/$whole$-$to$-$part relationships

An online admissions service in a hospital emergency department has several

tasks. It is responsible for printing patient wrist bands upon admission. The

basic wrist bands are assigned to one patient and a patient may have multiple

wrist bands depending on their needs when admitted. The basic wrist band

lists the patient's name, date of birth and family doctor. There are several other

types of wrist bands which include but are not limited to allergy wrist bands

which have all of the basic wrist band criteria plus the name of any

medications the patients are allergic to and children's wrist bands which have

the basic wrist band criteria and also list the name of an accompanying parent.

Each wrist band can be broken into two parts: the bar code section which

contains a unique bar code and the information section, containing specific

medical details about the patient.

Patients in the ER are also occasionally asked to participate in research groups to

evaluate wait times and the admissions system also tracks these groups. The

wait times group consists of $10$ or more patients and tracks how long they wait

in the waiting room prior to admission. A patient can be in only one research

group at one time.
