A relational system provides a way to store data so that it is later possible to go back into your DBMS setup and improve the performance of your program _without_changing_the_program's_code_. The ORM structure prevents this ability by abstracting away the meaningful structure. The database structures built are as good a DB organization as code generated by code generation programs: the meaning is obscured, and the generated (structure / code) is hard to work with.
