That is not very charitable of you, is it? I think it's fair to say that in many areas tools to interface with relational databases are lacking; consider the horror-shows that are Arel or Hibernate. Also, good schema design is not, in itself, a trivial task, especially considering how common ignorance of such principles are. In my experience, a not insignificant number of practitioners learn a "normalization" peculiar to a specific product--or even a specific product version--and apply this forward into the future to disastrous effect.
