QuackFuzed.com is the personal ColdFusion coding blog of Matt Quackenbush. It exists primarily as a place for the author to learn, and hopefully to assist others in learning and/or avoiding some of the same pitfalls and mistakes. (Quack certainly makes enough mistakes daily to make up for the entire ColdFusion community.)
Transfer: Many-to-One or One-to-One?

This post is actually a response to a post by Ray Camden. I planned to add a comment to Ray's blog, but I felt it was too long to be considered merely a comment. Here's a snippet from Ray's post that I am specifically responding to:

Also, I get that there are many emps to one department. However, when I'm defining the emp object, I look at it as defining _A_ employee. To me, _A_ employee maps to _A_ department.

A relationship is a two-way thing. So you *have* to look at it from both angles.
(A) Employee Object: How many Departments am I permitted to have? One? Many?
(B) Department Object: How many Employees am I permitted to have? One? Many?
The answer to (A) is still One, and the answer to (B) is still Many. No matter how you slice the pie, Employee > Department is a Many-to-One relationship.
