    Joe Celko did a much better job of explaining the nested sets model than I can, and since Joe frequently visits DBForums he may drop into this thread and contribute.

    I'd suggest that you read the appropriate part of his book Joe Celko's Trees and Hierarchies in SQL for Smarties, Second Edition before you ask too many questions. Joe doesn't have much patience with questions from people who want him to custom build them a solution for free, but he's pretty helpful to those who want education.

    In theory, theory and practice are identical. In practice, theory and practice are unrelated.
