What I was working on about 3 months ago (with Postgres) was to database
the WMO header, location and size into a database table. Use this as a
pointer to the data on disk. Dumping all the data into the Database
requires expensive cleanup routines and I figured it was easier to use
the database as a quick lookup to data on disk rather than dumping the
data into the database. This might be easier with Oracle or other
$500,000 databases which might have better garbage collection. In other
words, I was using the database in the same fashion I use header files
in WXP.
As for surface data, it is more regular and I played around with dumping
about 10 fields into the database and keeping a pointer to the last 24
hours worth of data. I just started this work but never got to the
point I was populating the database so I don't know about the
gotchas....
