I also did some experimental SQL implementation of TM with unmerging 
possibilities.
In my case each TM construct has additional information - set of 
"sources". It allows easily
to unmerge  full topic map. It also helps to unmerge topics.

SQL allows efficiently  filter by source.

I suggested at some point to include this feature into SAM  but...
we probably need more experimental work this area.
