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
...

It is exactly the opposite of no normalization. It is near complete normalization. Received on Fri Feb 27 2004 - 04:51:12 CET
