Isn't that where the produced work comes it?

If we find a way to combine CC-BY-SA and ODbL data in the rendering 
process where the ODbL data has already ceased to be a database when it 
comes in contact with CC-BY-SA data, then we're ok.

Provided that such a point exists. One could argue that in order to be 
meaningfully combinable with CC-BY-SA data, ODbL data still *has* to be 
a database, whether it is in the form of a bitmap or not... ;-)
