Henry, That depends on the question whether you want to make the implicit information in that SQL database explicit (in implicit representation lots of linking information is left out, because "you know what it means", and therefore requires human intervention). In that case it is anyone's guess, because the degree of implicitness varies enormously.

I can probably make them up, but who knows, perhaps someone has already written a calculator for this. This would be very useful in estimating what projects should would be initial candidates for putting online behind a SPARQL interface, given that current specialised triple databases can take between 20 million and 300 million triples.
