aggregation question

not sure why they don't show any collections as class members. my guess is because this is an example, not a detailed specification. if you did it out in all its glory you'd include more than you see on this diagram.

i agree that there's no reason for OrderDetail not to use aggregation/composition with Item. my guess is that this is a teaching example, not a rigorous specification.

i'd take this link as an example, a teaching exercise and nothing more. it's good that you're questioning what you see, because it implies that you have enough insight to think about the problem for yourself. but if this is your first tour through UML don't worry about it. suck up those main ideas and start using them for yourself.
