Good questions. I didn't envision defining constraints with DDS or SQL, or generating triggers, but it seems that some level of data validation needs to be available. I do envision enabling users to define drop-down and popup selection lists, where list values are defined in other tables.

I did envision a flag in the field definition to indicate whether a value is required (non blank) or not. I was thinking about enabling range validation for numeric fields, but hadn't considered date range validation.

Thanks, for the suggestion.

Nathan.
