I have several questions about UML diagrams as I am not finding them very clear (they are new to me).
1) When making a diagram with generalizations/specialization: if I do not have all of the possible child classes on my diagram and only have the main children relevant to me, do I still use a blank triangle for the connection?
2) If I have such a diagram and an entity (person in this case) can belong to multiple children categories, how is this shown? Should the fact that an entity(person) can belong to multiple child categories be shown on a UML domain class model?
3) If two of my children have a relationship between them, for the two children that are patient and physician, how is the relationship shown on UML? Is it just a line with a verb and notation (eg 0..1)?
Any advice would be greatly appreciated!
