LineItem in Cade's class diagram
don brown (aka brownie brownie)
posted 11 years ago
I've been studying the Case Study in Cade and i've been looking at the LineItem class in the Class Diagram and wondering whether i need to apply a similar concept to the Flight Segment relationship.
From what I can make out LineItem holds a number of priced Products. So the LineItem captures the notion of several Products at a certain Price. An Order will have a number of LineItems.
Is that the only reason for the LineItem class? Is its sole purpose to represent a Number of Products and perhaps a Price.
Is there an specific reason why Order has been decoupled from Product?
Don't get me started about those stupid
