Code from my Intro to OO presentation to the DFWCFUG
ColdFusionFor those that caught my mini-presentation to the DFWCFUG before Mark Drew's CFEclipse presentation on Tuesday night, I took a basic procedural code application and modified it so that all database interaction was managed through objects.
After the meeting for the ones that stayed around, I proceeded to take that application and turn it into a Mach-II application. While this was certainly a step in the right direction, the framework still knew too much about the application and was doing things it had no business doing, such as instantiating DAO/Gateways in listeners and doing business logic, rather than acting more as a traffic cop like it should.
Due to this I have added a fourth step in the application, which takes the Mach-II application, adds in the concept of a service layer which the framework accesses, and ties dependencies together using ColdSpring. All the while the functionality of the application doesn't change.
I have packaged this application up with a SQL backup file and
a README explaining how to set it up and with some description of what
is going on in it. Feel free to pull it down and play with it. If you
catch any glaring mistakes or have questions or suggestions feel free
to contact me.
If anyone is interested, and since so few people caught the last half of this application going from a procedural app to a Mach-II app, then to using a service layer and ColdSpring, I would be more than willing to do this entire thing as a meeting topic one night if anyone is interested. If so, please let me know.

We're booked for next week, and then will be on hiatus while at CFUnited, and perhaps doing live interviews from there. But we would be glad to schedule you for the first week of July, or whatever works for you. Any day and time you may prefer. Let me know if you may be interested.
great, thanks for this! This will be really helpful to me. You know what would be cool is adding another level 5 and showing how to integrate reactor or transfer into MachII. I just started using MachII myself and I think I'm starting to get the hang of it. Now I need to get my skills to the next level, coldspring + whatever ORM.

Might be useful to some. Again thanks for sharing this.
