This discussion is covered in the book 'Oracle Design' from O'Reilly ( sorry to the authors but I can't recall your names ). They cover it briefly, at least in the first third that I've read, but provide an appendix that provides a generic approach that can be used. It makes use of flags, triggers and procedures and appears to be of the same quality as the rest of the book.

Anyhow, I don't have the book here with me but I would recommend it to not only help solve this type of problem but to also for providing thought provoking ideas at solving other Oracle problems aswell.
