Technique of spatial data editing via web browser described in this tutorial is extreamly easy:
Ext, GeoExt, OpenLayers Geoserver and WFS-T do all dirty job, and you do not have to code anything server side. All UPDATE, INSERT & DELETE queries to database are done by via WFS-T.
Is there something like this for non-spatial data? What will handle store-to-database communication as good as WFS-T? Abovementioned solution is also good for non-spatial data but I would like to avoid using geoserver all the time
