Less than two weeks ago, I posted my Database Survey. As of just a few minutes ago, I have had 215 responses. That's pretty awesome. I'd like to get at least twice that though.
I haven't looked deeply at it yet to see if there are any trends. I think it will be best to wait until the survey is closed. I did look at some of the responses, kind of as a quality check. Looks like MySQL is fairly well represented. I didn't see any DB2 responses (for primary database). I did see plenty of Oracle and a few Postgres.
I will leave it up for another 2 1/2 weeks (for a total of 4 weeks). If you haven't taken it yet, please do so if you get a few minutes. It only takes 5-10 minutes as there is only 25 questions.
Also, if you have a blog, post on forums (without spamming), or have any other ways to spread the word, I would appreciate it.
