To a limited extent only. It does not make sense to have a jillion different conventions. Unless one convention is largely better than a standard, it is best to stick with the standard. Relational is pretty flexible for most things (especially if you have a good DB or table engine). Thus, I see unsufficient reason to translate back and forth between relational and navigational for most custom software. Since RDBMS are not going away anytime soon, it makes sense to embrace relational than to fight it with thick wrappers and translators.

However, I understand that some really like navigational viewpoints and claim to work better under them. It is hard to make everybody happy. It would be interesting to find the psychological reasons behind the differences in preference.
