I find the OO still helps for data mapping even in fairly simple, data
centtric apps. I love to be able to ask for User.FirstName,
User.LastName, Boss.Title and Auctions.TotalSpent and get that without
having to write the left outer joins and aggregates by hand. But maybe
that's just beause I suck at SQL :-)
Its also nice to be able to Order.getAssociated("Items") or
Author.getAssociated("Articles") - I find that stuff is just nice.
Best Wishes,
Peter
