Hi John,
as far as i've now read other messages to this thread, i would like to
underline your words. From my point of view (a database designer's view) there
is a missing layer betwenn the object model and the schema. Whenever i do
normalization works or (more worse) denormalization works, i have (a) to handle
hundreds of "columns" within the schema or (b) to modify the object model what
is not amusing for the rest of the crew.
I think that designing enterprise size databases does not mean supporting
enterprise size dbms. It means supporting the requirements of database design
in an environment with purely relational and very big databases, which can not
be generated directly from out the object model.
