My stance is that there should be a dividing line in the application. On the right of that dividing line is the code that knows about SQL and the Schema. On the left is code that knows nothing of SQL and sees the schema through an abstract vision. (i.e. the schema has been transformed into a more convenieht structure). The dependencies that cross this line should all point to the left.
