Now, that being said, lets say you did an analysis and found that the
two databases had no overlap, or at least very little (I have no idea
what very little would mean in this case). You could probably
convince yourself, and it's math and statistics so I'm horrible at it
but I'd beat some folks on this list could provide a formula, that the
amount of overlap is statistically insignificant. If you could do
that then you could combine the databases, in which case I leave it as
an exercise to the reader.
