$3\mathrm{.}12.$ Derive the domain model for the patient monitoring system from Problem $3\mathrm{.}11.$

$($a$)$ Write a definition for each concept in your domain model.

$($b$)$ Write a definition for each attribute and association in your domain model.

$($c$)$ Draw the domain model.

$($d$)$ Indicate the types of concepts, such as $$boundary$,$control$,$ or $$entity$.$

Note that you are not asked to derive the use cases for this system $($see Problem $2\mathrm{.}14).$ The description of the system behavior that you will generate in the solution of Problem $3\mathrm{.}11$ should suffice for deriving its domain model.
