GML as transport agent for sdbms

["Parang Saraf" <parang.saraf@gmail.com>]

Hi,


I am trying to develop a decision support system
which takes in information from a spatial database, perform some
queries and publish the result in a well structured form(GML/XML) so
that it can be used by the users. It should also be able to input
information from the user and update the database accordingly. 


I am having a spatial database (Postgres-postgis / oracle ) having
spatial data. Now I want to use GML/XML as a transporting agent to do
this data transportation for me. I should be able to take the GML data
from the user and store it in the database and vice - verse. 


I randomly did some net surfing, read some papers and books on XML/GML
for finding out a way to do this. But still i am not able to find any
heading. I am relatively new in this field.
I will highly appreciate if you can guide me in this regard or can
provide me with some links or similar work, basically some sort of
heading. 


It would be a great help If I can get some example xml/gml files and scripts for doing this work. 


Thanks and Regards
