I've seen numerous threads on this list that mention this Person "has a" Role model. Would anyone care to share how it is implemented?

Some would say that it is more correct to model it this way: a Person has a Role, and have Employee, Customer, and Vendor extend Role ... In general, it's more flexible that way because people often change roles, or can have multiple roles in a system. At least that's what i've read here and there. Hopefully someone with more experience can comment. Then it seems Address is more clear, a Person has an Address and has a Role, and Employee, Customer, Vendor, and whatever else comes along later extend Role - at least that's how i see it. My 2 cents, never try to "take a shortcut" with extension - you'll pay for it later - unless of course you like learning everything by experience. And if you are the type that HAS to learn everything by experience, like me :), then i would suggest trying to "take shortcuts" with extension on as small a system as possible. :) nando -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mehdi, Agha Sent: Wednesday, March 03, 2004 7:27 PM To: '[EMAIL PROTECTED]' Subject: [CFCDev] Objects Hi, I am designing an Object Model for one of my applications and this is my first time doing that. I have a Person Class as the base class and Employee, Customer, Vendor Classes extend that class. I also have an Address Class that works as a subType of each of the subClasses. The Person Class also holds communication information like homePhone, cellPhone, workPhone, fax, email etc. I was wondering if it would be worth doing to create a separate class for communication attributes to work as a subType for Person Class. Does it seem to be a good way or just another step?
