[ic] Replacing SQL Databases

[interchange-users@interchange.redhat.com (Jerry Brady)]

Racke,

If your customer is uploading a complete set of data, then you can
simply reload the entire database.  A customer of mine uploads current
product data nightly and I wrote a script that creates a new
"products.txt" file automatically.  

I have a cron job setup that checks for new data.  If new data is
present, the script deletes the products.sql file from the products
directory, installs the new products.txt file and restarts IC.  IC takes
care of dropping the existing table, creating the new one and adding all
the rows defined in products.txt automagically.

You may run into a problem if products that are linked to current orders
are dropped after the update and I'm not sure how much of a problem this
would be.

This only works if you customer is sending all of the data with each
update.  If they are sending deltas or smaller updates (adds/drops) then
you'll have to build something yourself to let them administer their
products database remotely.
