stock control - you have rto make this easy for yourself, you're either
selling a carton or a packet. If you sell a packet, your operations should
be to first split your carton intro packet stock - then sell a packet
every time you deploy a new versin of the DB, keep 2 copies running on your
dev machine (master and target).
work thru dev updates, then when ready to deploy do a DB compare
(IBExpert/Workbench etc) to create a script.
Rund the script against your target to confirm your script.
Then deploy your script
then start the cycle again.
