I can't recall what they do at SLAC, but I'm not sure that these large
scientific data acquisition projects require a transactional database
at all, sure writing the data to your storage medium is going to be a
real headache - but if you lose an hours worth of data does it
actually matter, do you redo the experiment, do you do similar
experiments or do you move on.
