I'm doing a conceptual class diagram for an app that lets:
Clinicians view the patient's lab results and their calculated Reynolds Risk Score.
Clinicians make changes to one or more of the patient’s lab results to see how the patient’s current Reynolds Risk Score could be improved.
My question is: Should Reynold's Risk Score extend from the lab measurements class because it's derived from it or should it be a composition or should it be a normal association?
To model scenario 2, do we have to draw an association from clinician class to patient's vitals class and another association from clinician class to Reynolds Risk Score since changing the patient's vitals also changes the Reynolds Risk Score?
