OK folks, August FoxPro Advisor just hit my desk. Page 58, "Empower Your Users to Adapt Business Rules" by Charles Blankenship - and I *ReallyReallyReally* like this approach of table-based validation of Business Rules for an app, that can be maintained over application life via UI!!! I think it's an excellent approach to developing a robust app that's rule intensive. AND it gets me around the dbc's clunky field rule message dialog.

But there's one thing I don't get with this approach. Blankenship talks about "Enterprise-wide data validation" on page 65. But I don't see how having my business rules in a table is going to do me any good if my users want to ODBC access to my app's data? IOW How would you trigger validation via ODBC with this approach?
