There have been some comments from people who cannot imagine that a
large database might be valid. That simply shows a lack of
imagination. Here are examples.
Even the NYS DMV database is over 4GB. It has 20M records of drivers
and vehicles, each of over 200B. That DB is online, accessible by
every state trooper.
Mike Stonebreaker tells us to learn the term 'petabyte'. You probably
didn't think that that term was useful. However:
The Landsat tape lib in Sioux Falls SD has 50-100TB, i.e., 0.1PB.
That's on tape, but for serious datamining, to detect things like ozone
holes, online would be better if it were possible.
In fact, Stonebreaker claims that the storage and processing of large
raster databases is the most important problem in database design.
He's trying to do it, in Postgres.
Finally, using synthetic aperture radar, it's now possible to digitize
the world at about 1m resolution. How do you store the data?
