Shown below is roughly how to do it in RDM, I use "->X" syntax, instead of IDs to make it easier to following the referential links.

T_Person
Name, Age
->john, ->28

T_CompositeSymbol
AtmSym1, AtmSym2, AtmSym3, ...
->j, ->o, ->h, ->n
->j, ->o, ->e
->2, ->8

T_AtomicSymbol
a
b
c
...

> How is that different from no normalization at all?

It is exactly the opposite of no normalization. It is near complete normalization. Received on Thu Feb 26 2004 - 21:51:12 CST
