I'm experimenting with DBIx::DataModel.

I just played around with the Quickstart and am now moving on to the reference docs.

Certainly DBIx::Class has the largest and most active community of developers.

You could also look at Fey::ORM but I find it a bit cumbersome. Well written and based on years of experience with his prior project Alzabo but nonetheless too much work and too little convenience.

Finally, you might help complete whatever Oracle support is lacking in Rose::DB::Object.
