I disagree. A database is a resource that must not be taken 
lightly, as it has the strongest performance implications if 
treated wrongly. Luring people into the illusion that they 
can do away with it by the push of a button has the potential 
of generating disappointments. 
IMO, a good O/R framework must either exploit or allow easy 
access to the full capabilities of the underlying DBMS. And 
in a corporate production scenario, you will almost always 
have to map your objects to a pre-existing schema.

I see a value in generating default mappings as a starting 
point for projects that have the privilege of starting from 
scratch, however.
