Do you know which open source feature is the most important? Do you know which open source database rocks and which one sucks? Is MySQL better than Postgres? Is Ingres worth considering? How does Firebird compare? Have you used, or have you considered using, an open source database?
Take a survey. It's only 15 questions so it takes just a few minutes.
I'll post a link where you can get the results once they have been compiled and prepared.
BTW, this isn't my survey. I'm just passing on the link.
