It's about screwing up performance by using lookuptables. depending on the way you use VFP as a front end-tool you already use the VFP database as basis for your connections and views. I don't see any problem in adding a few lookuptables also (maybe also data for OLAP so the server don't get stressed when querying large reports)

I have found that DBA's are more anal about their data. It's theirs and we can just borrow in, manipulate it and add to it. but in the end it's still theirs.

Localy cashed lookups are good. State Names and postal codes are great. Customers are not. Inventory items are also not.

Are you, we speaking of a WAN interface spanning countries or cities? Or is this more of a big campus environment. Granted you do different things depending on your environment. Heck there is more than 1 server dishing up winzip7 downloads.

I guess the point I am making is that we have to listen to our customers about what they want not how we are going to deliver it. The current project I'm on is BASS ACKWARDS, but I just knod my head and go no problem.
