Software Design Patterns
First of all, thanks so much for the great feedback.
As a result of this feedback, I am revisiting my design (that I inherited from another source) and recognizing patterns that are in it already. And re-working it.
Anyway, I wanted to post this link to examples of the GOF's design patterns, mostly for my own reference later.
