Every morning at 7:15 the employees table was dropped. All the data completely gone. Then a csv from adp was uploaded into the table. During this time you couldn't login to the system.

A database may live forever, but our login system was limited by the calendar. I don't mean an actual calendar. I mean a database table called calendar. What did it contain? A manually filled-out calendar. When asking our resident shaman (who went by the name Munch), he informed me that when the calendar runs out we can't login to the system. This happened a few years ago. So they had an intern fill out 5 more years to make sure it didn't happen anytime soon. What system used this calendar? No one knew.

SequenceKey 1251238 For ease of understanding, I have recreated the whole of the SequenceKey table above. Yes. You read that correctly, this is the whole table. A table with a single key and a single value. If simplicity is a virtue, then one might declare SequenceKey to be the perfect table. What could be simpler?
