So far this environment seems to be much more stable.

The vendor and their client base seems to echo that the FoxPro environment is "rock solid" even at large data volume levels. Can any of you FoxPro experts out there validate this? Point me in the right direction. It seems like our data volume needs might push this product offering into an uncharted area. I would like to put this issue to rest for our CEO who has great concerns based on his fears from our Xbase/Clipper past.

Hi Ian,

your questions are not easy to answer. It has a
lot to do with the table structure, with the kind
of indexes, how data is updated (only online, or
online and batch at the same time), with the data
model, and so on. What is the expected increase of
data in your 1 million table ???

The are certainly other solutions who may give a
better environment (like a full blown database as
oracle or sql server).

A very good extension to the vfp database container
to handle problems with the dbf file format is STD
from www.stonefield.com, but it has to be integrated
by your vendor.

In FoxPro Advisor was an article about a fox database
of 120GB used for the EuroTunnel (railway tunnel beneath
the sea floor between UK and France).
