Ok i'll write up a little treatise on CFCs in a real estate app for you - a simple one that just manages inserts, edits, deletes and queries on a table of property listings. I'll take one that i use for my client (the one i think is the same as yours) and fictionalise it a bit to protect the IP of my client. You'll see how it works, and how you can integrate it with your user interface code. Also it will mean i can share it with others if they want. (I'd blog it but i'm too lazy to maintain a blog - i dont have one. I know what they're like to keep going - i had one years ago before they were called blogs.).
There's a WHOLE LOT more you can learn but i'll keep it to the basics for you and try to keep jargon out of it. Another nice thing about having a defined pattern to your code, is that you can have other stuff write a lot of the code for you. I have a little application I wrote to examine a database table, and write all the queries to add/delete/edit/read from it and produce the CFCs for me - that's too advanced for you just yet but if you see that at work, you can see one of the benefits of using patterns to your code. That's what some of these frameworks do - things lke Transfer and Reactor for example recognise when you add a field to your database table and re-write your CFCs to match. Without ever seeing that at work, I am sure you can see how that would be of benefit to you as a developer where time represents dollars. Coldspring is another tool - it knows how to instantiate your CFCs and whenever you call for a CFC, Coldspring knows what to do and just creates it for you, guaranteeing it feeds the CFC everything it needs to know. And it knows which CFCs to cache in memory and which to destroy after each use. It's a marvel! But for now lets leave all that stuff aside, with the understanding you'll want to know about that a bit down the track. I'll write some stuff tonight for you and hopefully have it for you tomorrow. It's Saturday night and i dont have anything to do. (jeez i'm OLD already!!) Man you've come a long way in a short time - from being in the ColdFusion stone age (i.e. CF4 wasn't it?) only a few months ago, now you're moving up to the cutting edge. Believe me, when i jumped into this OO pool, it revolutionised the way i write applications, and made possible - even easy - things i'd have scratched my head about in the old days, thinking that was beyond my capabilities.
