It seems to be based on the honor system. When you click "Rank", it asks you what databases you're familiar with. Then you can stack rank those databases across various questions. It's possible people could lie and say they know about mySQL and Postgres when in reality they don't, but hopefully the overall results would be accurate. Actually one of the reasons I posted it here was because I was hoping more database experts could weigh in with their opinions..

Does it say anywhere on that site if the people surveyed know both databases well enough to judge these questions? I can't find anything about that, and the site also ranks gin and martial arts, so I'm not sure sure it has much value.
