Hi John,

First, let me state that editing shapefiles is one of the many uses of 
VFP that I am trying to replicate.

All FOSS4GIS provide shapefile attribute editing capabilities. Most are 
just simple viewers. On a regular basis I import data from shapefiles 
into VFP, manipulate the data with numerous SQL then relate the table 
back to the shapefile's attribute table and copy the results across.

Obviously, I could use any of the main geosaptially aware databases to 
manipulate this spatial data if I wanted to import then export the data 
but I am trying to keep an existing file format until something better 
suited to my business is supported (e.g. SQLLite+SpatialLite). The other 
problem is that I generally value add to a project and clients need the 
data back in the format they provided -- for better or worse this is in 
shapefile format: shapefiles use dbase files.

The tutorial you pointed to actually illustrates how you can import 
shapefiles into PostgreSQL+PostGIS. I am aware that routines are 
available for importation and exportation of shapefiles. This is an 
option but as stated above this merges many datasets into one enormous 
file. This would make backups, data directory synchronisation and 
dataset management a nightmare.

Cheers Simon
