hey,
: The overhead of XML is still too great to handle seismic surveys. It's
not
: uncommon for seismic surveys to be 100+GB. I've even seen one survey that
: was almost 1 TB big! Yes, it was loaded all on the same machine at one
: time. Typical workstations (not servers--desktop workstations) will have
: 200+GB of disk space, with some special-purpose workstations having far
more
: than that. I'm not sure it really will ever be feasible to store seismic
: data in XML.
as xml compresses extremely well, having it put to a zip file would help a
lot IMHO, and then use zip input streams for parsing when needed. on the
other hand, there are ways to use things like windows disk compression for
handling such completely transparently, though I'm not familiar with the
implementation of such mechanisms. the drawback is that you loose some cpu
power. just my 2ct.
