CERN has the one of the largest databases in the world. It's nowhere 
near a classical database. It isn't even relational. It's just many 
Petabytes of flat binary files. CERN and other large research labs such 
as SLAC have been doing this sort of stuff successfully for decades.

Similar story for other huge science databases such as the SNAP 
satellite supernova database - http://snap.lbl.gov/
