  I would say that the case is more that the principles embodied in the rela-
  tional model are "universal" data organization principles.  E.g., we tried,
  to whatever extent possible, to apply normalization, reduce redundancy, etc,
  while we were still using Codasyl-based systems.

  Packages which present a relational logical view to the programmer have the
  attribute of making it easier to adhere to these principles.  I say "logi-
  cal view" because in reality, are there any systems out there which are 
  truly relational internally ?
