DataSpan Technology Inc. is a Calgary-based company engaged in the
business of digital data capture and conversion of maps and
engineering documents.  We are investigating the possibility of buying
a commercial database to supplement or replace our current in-house
database.  Therefore, we would like to find out what other companies'
experiences are in developing or purchasing databases for applications
similar to ours.  Among the questions we have are:

- how does it perform on large maps (on the order of 10,000 to 100,000
objects)?  This includes speed and memory usage.

- does it support concurrent updating and access?

- how easy is it to implement spatial relationships?

- how expensive is it? [can't forget that one :-)]

We are particularly interested in the relative merits of relational
versus object-oriented databases.

Please respond via e-mail - results will be posted to the net if there
is sufficient response.  Thank you.
