Are Triggers a "Legacy" Feature?
It is late evening. Something is wrong with a database. You narrow down the possibilities, getting more frustrated and puzzled. Stay calm. Check the inputs systematically. No!

Where are all the MVBs?
Whereas there are plenty of experts prepared to help with the technology, few seem to come forward when the struggle is against the bureaucracy rather than a recalcitrant server. Where are all the SQL MVBs (Masters at Vanquishing Bureaucracy) when you need them!?
