I'm really tired of half-baked interpretations of the relational model by you and others
of your ilk (vendors of ad-hoc database systems).

There is no "general form" of normalization. Rather than educating yourself on the issue, you take a summary of the concept (a single sentence in this case) and go off on a ridiculous tangent.
Items like 'john' and 'o' (as in 'john', 'god', 'neo') are values. Non-redundant storage of values is a physical issue. Normalization deals with the logical view of data. Normalization is concerned with information or "facts", not storage of values.

This makes no sense. You're just making this up as you go along. Much like your ramblings about the human brain (which are OT in the comp.* branch).
