I'd suggest creating a pair of test systems, one with a single table, 
one with many. Write a program that populates each with the same large 
set of randomly generated data, measure memory usage and performance for 
some typical queries. I'd expect that the results will prove that a 
single table works best. However if it doesn't, at least you have a 
justification for making a more complex, more expensive (to develop) and 
harder to maintain solution.
