I would like your opinions about the following framework. http://www.justingiboney.com/code Does this framework already exist in cocoa (did I reinvent the wheel)?
It looks like you're doing the same kind of thing as NeXT's EOF (Enterprise Object Framework), which is long gone but much of which resurfaced in CoreData.
There are a few existing frameworks that do this sort of thing but use sqlite to manage local database files. One thing you might consider is taking one of those and replacing the parts that use the sqlite3 API to talk to your database API instead. I've used Tito Ciuro's QuickLite <http://www.webbotech.com/> in the past, and it's pretty good.
Is this a framework that is used (or likely to be used) in the real world?
In certain types of apps, yes :) I just don't think many people are writing these types of apps in Cocoa. This type of enterprise software usually seems to be done for Windows, or in Java or as a web service.
Those classes are a start, but they leave all the hard parts as abstract methods to be filled in, so I don't think they'd be useful on their own to anyone else. Once you implement and debug the whole thing it'd be very useful, but that ends up being an object-relational mapping framework; I've done that (in C++) and it's really damn hard. It would probably be much, much easier to adapt an existing sqlite framework like QuickLite instead.
