My favorite part of the database...

[dorchadas]

...is when someone hits the "Ruin the entire data set" button, which is conveniently set right next to the "continue your work" button and has no confirmation dialogue after you hit it.

(At least we caught it right away this time! Last time the process went a lot further along before I noticed something was wrong and it took a week to fix. The problems with large data sets)
