[Kexi] Sqlite, Spatialite, ODBC and Kexi

Thanks again for your reply.
My idea is to use Kexi as user interface for my forest management and
carbon sequestration linear programming modelling so farmers and
foresters can use it very easily.
I saw great potential of using Kexi since there is business graphics
included for the results aside from interface into database i.e.
sqlite / spatialite and postgresql / postgis. Spatialite and PostGIS
are spatial databases.

This is good news.

Yes, I did this. This is not the problem for me. I can always create
the tables and let the user input the data or import the data.
As mentioned, the end users are farmers, land owners and forester who
are not really keen doing these things.

My problem is reading the kexi file outside kexi thru odbc.

Yes, this is good idea. I use .loadshp in spatialite to import
shapefile (ArcGIS polygons and data into spatialite.

Support for sqlite in Kexi is winning feature for Kexi. It attacks a
lot of users especially non programmers. Linux needs filemaker
alternative and every filemaker users is looking for support for
sqlite and postgresql. Augmenting the business graphics would be good
as well. If there is support for python, we can use matplotlib for
graphics. It just need a matplotlib container similar to Orange.
I tried glom and I think kexi is far advantage than glom.
Kexi just needs some examples included in the package so users can start using i
Thanks a lot.
