I can't say much about AR and ORM designs since I haven't used them at
all. But it is that *exact* same reason as Paul mentions above that
bothers me too. As I mentioned on #solarphp, it makes perfect sense to
me that a model (table object) represents *many* records while a
record (or a row) object represents *one* record.

This is something I don't quite understand. Could someone explain to
me why is it neccessary or better to have business logic in the record
itself rather than in the model object.

I have yet to be convinced to the record-based approach. The table
stuff seems more sane to me, at least for now. I'd like to hear more
opinions about this. Any Zend guys near by?
