I've heard before that every table have a header, and that if someone alterate the header, the table won't work until the values in the header are corrected again. I think this is kind of a cool way to secure our data. The only problem is "How can I edit the values in the header of every table"?

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
