Yes, I used it for several commercial projects and it's really  
usable. After some necessary updates to Valentina THIS is a dream  
team regarding speed.

BUT there is still no documentation, real samples, ...

And as Ruslan already "announced" at the moment I' totally unsure  
about my further direction, especially using RB, there are so many  
bugs (i.e. the new introduced external shared property bug)  and old  
bugs ("automatic method renaming") ... the I spend more time to fix  
RB bugs then to develop my framework

If I would do it, I would look at Apples Enterprise Objects  
Framework. It's the most mature and IMHO best O/R-mapping on the market.

But IMHO there is no real "easy" way to port this to REALbasic,  
because even while RB is a OO-tool there are missing some key  
features and implementing this on your own, means you're going to  
really bite the bullet and you start moving more and more in your own  
world instead extending REALbasic. Look at my framework and you're  
going to get a picture what I mean.

To start it's perhaps better to look at Hibernate. It's not so mature  
as EOF, IMHO EOF is better, but Hibernate is OpenSource and there are  
tons more of documentation available.

Contact me of list if you want and we check what we can do to port  
your current application to my framework.

If you really think about a redesign of your app you should use  
2007R4 or even better wait for the 2007R5 beta! There will be really  
important things deprecated and new bugs introduced.
