Above is a class diagram extracted from Chapter 11 - UML and Programming of Martin Fowler's
UML Distilled. I have a question about the multiplicity on
Phenomenon Type in associations with
Measurement and
Phenomenon. Why a Phenomenon may not have a PhenomenonType while a Measurement must have a PhenomenonType? Can anybody give me a example of any Phenomenon that can not have a PhenomenonType associated with it in term of
Patient Observation? TIA.
