Hi Listers!,
=20
Here's a topic that I would love to get your thoughts and ideas on...
=20
I work for a Consulting company that specializes in Aquatic
Environments. Currently, myself and another fellow are developing a
substantial Information System to handle all environmental data (mostly
aquatic) that we collect in the field...fish, lower trophic/benthic,
water. MS Access is being used to store the bulk of the 'aspatial' data
(although ultimately everything in this is spatial), while the spatial
data (bathymetry, macrophytes beds, etc) is as you may have guessed
being stored in a Personal Geodatabase using ArcGIS 8.3. I use an ODBC
connection to bring the Access database into ArcGIS, and am capable of
performing joins, relates and queries on the Access database right in
ArcGIS. The spatial link between the two is provided by the Sampling
sites which contain a UID and coordinates (and several other data
fields), linking the tables in Access to a geographic location. Please
note that I'm working on a budget with the tools that I have. So far,
the system's interoperability is very good and I'm happy with it.

Here's some seed questions I hope you can 'run with':
=20
(1) Interoperability - what are your thoughts on using connecting
these software tools to build a large GIS?
(2) The Future - Do you see the ESRI Geodatabase and MS Access
database becoming obsolete? (For example, if and when the Object
Oriented Databases take over and Relational Databases disappear)
(3) Migration - How do you foresee migrating datasets from these
packages into potential future packages?
=20
Have a great day and thanks in advance,
=20
Bill
