request for comments - SDE

[Gernot Rücker]

Hello Steve, list,

I personally think that using SDE as a data processor might have some
advantages. Although I never did any programming using the SDE API myself I
think that there is a lot of functionallity in it that would be very nice to
have access to. We are thinking about using MapServer and ArcSDE to serve a
large amount of data over the net. This data should be accessed by users
using RDBMS and locational queries. Anyway, I did not yet get to play some
more withg it to get a deeper understanding on how map server and SDE work
together - so maybe I am not yet in the position to give a fully qualified
comment on this.
I would also like to know if there are any plans on providing access to the
Oracle Spatial Data Object datatype.

Gernot
