That's the whole problem -- if another programmer uses a db call with internal values then the Input Transform rules would be bypassed, leading to the possibility of duplicate entries.

One could provide a special API for handling that field but once again if somebody doesn't use that API you're back to the data quality issue. That's why I'm trying to accomplish this with db rules.

So how does one enforce this uniqueness rule even if using DB calls with internal data values?
