Perfect, fast, simple and powerfull. With Rose::DB::Object::Loader you can use existing models without coding! Just set connection options for your existing DB - and that is all - You can use your Database as a Model. For more information take a look at "The loader" section in the Tutorial.
I have perfomed some tests Rose::DB::Object vs SQL Abstract(with DBIx::Simple). In real world tests the perfomance is identical to both or Rose is faster!
Perfect Web Framework. Very simple to deploy and distribute your projects with Mojolicious. You need to know that you can develope not only web sites! The main benefit is "all works out of the box"
