We would like to set up a seismological database, and are
looking for a good database system for a MASSCOMP machine.
(MASSCOMP is a 68000-based machine which runs its own
version of UNIX--a problem in itself). Does anyone have
experience with a relational database system which works
well for scientific data? I'd like to hear (by e-mail)
the pros and cons of your system, especially in relation to
the wish-list below (numbered in order of priority).
1) can be brought up on the MASSCOMP UNIX
2) is sold by an established company which is unlikely to go
belly-up and is likely to fix bugs in new releases, which come
out regularly.
3) has a way of allowing back-up storage to a file, etc. which
does not lose precision.
4) has a query-type language for accessing and formatting data easily.
5) allows scientific functions in such a language (e.g., square roots,
logs, exponentials)
6) allows storage of data in exponential notation
7) (one can always hope) has a date-time storage type which stores
fractions of a second and/or takes leap seconds into account.
Thanks in advance for your help.
