问题 I've been working on putting together a rough conceptual model of an E-commerce website that basically allows users to resell concert tickets. It's purely conceptual and not something i'm actually making! Anyway I've put together a domain model and I was hoping for some feedback.

问题 I'm having a pretty hard time trying to figure out how to model a certain scenario as a UML design class diagram. Suppose I have the following situation: I have a class named CPoint that has two attributes: x and y (coordinates in a R2 plane). In the other hand, I have a class named CLine that should have two CPoint as attributes. This is pretty straight forward to code (I'll use C++ in my example): class CPoint{ float x; float y; //Constructor, gets and sets here } And for CLine: class CLine

问题 I tend to design my classes with properties sorted in an order that makes sense to me. For example; I always make critical info like 'id' near the beginning, followed by less & less important data, and finally record meta data like 'create date' near the end. But when I add the class to Visual Studio's (2010) class diagram, it sorts the properties alphabetically. Is there anyway to turn this functionality off? Edit (11/05/11): For example, I have the following class public class Email {
