THIS IS A BIG QUESTION OF 5 PARTS DIVIDED ON 5 QUESTIONS, PLEASE ANSWER
THEM ALL TOGETHER:
For a long time, the Royal Victoria Hospital (RVH) worked with an information system that
consisted of a mix of paper-based files and small independent databases developed within some
departments. The new administration has created an information system (IS) department, and
they hired you as information officer: head of the team in charge of the design and
implementation of a new global information system. The following information was collected by
the first team from the IS department, who conducted interviews with some of the hospital
administration and staff to identify entity types for the hospital.
The hospital depends primarily on four groups of people: employees, physicians, patients, and
volunteers. Of course, some common attributes are shared by all of these groups: person_ID
(identifier), name, address, birth date, and phone number. Each group also has at least one unique
attribute of its own. Employees have a date hired, volunteers have a skill, physicians have a
specialty and a pager number, and patients have a contact date (date of the first contact with the
hospital). Some people may belong to two or more of these groups at a given time (e.g., patient
and volunteer).
Patient: A person who is either admitted to the hospital, or is registered in an outpatient program.
One, and only one, physician is responsible for each patient. Patients are divided into two
groups: resident and outpatient. Each outpatient is scheduled for zero or more visits. The entity
visit has two attributes: date (partial identifier), and comments. Note that an instance of visit
cannot exist without an outpatient owner entity. Only resident patients are assigned to a bed, and
a bed may or may not be assigned to a patient.
Physician: A member of the hospital staff who may admit patients to the hospital, and who can
administer medical treatments. A given physician can be responsible for zero or more patients at
a given time.
A patient must be referred to the hospital by exactly one physician. A physician can refer any
number of patients, or may not refer any patient.
Physicians may perform any number of treatments on behalf of any number of patients, or may
not perform any treatment. A patient may have treatments performed by any number of
physicians. For each treatment performed on behalf of a given patient by a particular physician,
the hospital records the treatment date, treatment time, and results.
Employee: Any person employed as part of the hospital staff. Employees are subdivided into
three groups: nurse, staff, and technician. Only nurse has the attribute certificate, which indicates
a qualification (RN, LPN, etc.). Only staff has the attribute job class, and only technician has the
attribute skill. Each nurse is assigned to one (and only one) care centre. Each technician is
assigned to one or more laboratories.
