Exactly, I have a pretty good idea of how to code and use inheritance (designing them is another story). My example was supposed to be an example of relationship that WAS NOT inheritance, and how would one code cfc's for this relationship? -------------- Ian Skinner Web Programmer BloodSource Sacramento, CA -----Original Message----- From: Joe Eugene [mailto:[EMAIL PROTECTED] Sent: Thursday, September 04, 2003 8:01 AM To: CF-Talk Subject: Re: CFC/Object Best Practice > practice to code this relationship in an CFC.

An example of Inheritance would be some like Dog - Hunting dog - Pet dog Both Hunting dog and Pet dog inherit the properties of DOG...(ie all Dogs have 4 legs, 2 eyes, nose etc) while Hunting dog itself has the extensive properties/features of a Hunting Dog(vigilant ...)
