I think you are looking at Class::DBI from the wrong angle - Class::DBI is not a tool to force existing tables (and their relations) into classes/objects, but to provide some simplicistic way of storing objects in tables.

Class::DBI isa Ima::DBI and thus has support for adding custom SQL constructors if you need to create an object resp. find an object through a complex query which you don't want/can't reproduce via Perl.

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web

My thoughts were the exact opposite -- Class::DBI is an abstraction layer that let's you interact with your tables as objects. Throughout the documentation, when the author refers to 'objects' he generally means 'rows'.

Not that you can't do that. I'm only saying that Class::DBI is not going to necessarily make it easer to represent class inheritance in a relational system.
