There is no simple, normalized and NULL-less solution to your problem
with a RMDB. If you could post some actual data, I can show how dbd
handles it and one of the RM experts can design a schema that meets
your needs. What exactly are you needs? Are you trying to avoid NULLs
and or redundant data or more than X number of tables?
