Emulate a client/server model using TCursors and libraries. Extract the
data you want to private tables and use those in your forms. Whenever
you need to update a "real" table use a tcursor.
It's a lot of work to begin with but once it's set up it's RAD.
But if you're going to do that, you may as well go all the way.
