SQL Keys in Depth
The internet is full of dogmatic commandments for choosing and using keys in relational databases. At times it verges on a holy war: should you use natural or artificial keys? Auto-incrementing integers, UUIDs?

Many arguments about keys boil down to false dichotomies and failures to acknowledge other points of view.
