I must agree with you. That kind of mapping is nice until you realize 
some specific operation must really be super fast, and the only way to 
do that is with a custom, super specific query... and then you start 
breaking all that abstractions, and everything results in a mess. Pure 
SQL, abstracted by convenient methods, is what I prefer. These methods 
may return objects that represent entities.
