Draw the domain class diagrams Scenario:

Patient Administration System
A local hospital has a large number of registered physicians, each with a unique physician
number. Physicians all have at least one specialty. Patients are admitted to the hospital by
physicians. The hospital keeps track of the patients’ names and addresses, and assigns each
patient a unique patient identifier.
Any patient who is admitted must have one and only one admitting physician. Once
admitted, a patient must be treated by at least one physician. A particular physician may
treat any number of patients, or may not treat any patients. Whenever a patient is treated
by a physician, the hospital wishes to record the date and time of the treatment

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
