After reading your previous post about virtual columns I had some similar thoughts about using virtual columns for business rule validation.

What about just adding a generic RECORD_IS_VALID virtual column to a table? With – as you suggest – a check constraint to ensure that the value of the virtual column is always “Y”.
If we base the value of that virtual column on a “validate_record” function that accepts the values of all “real” columns of the table, this “validate_record” function could be a generic “hook” to other functions that do the actual checking of individual rules. A kind of alternative framework for business rule checking, that does not clutter up table definitins too much. Just some thoughts…

Eric
