One of the more common queries I hear is, "What database should I use under Linux?" That is actually a pleasantly difficult question, because there are a number of choices that depend on what you want to do.

But if you are looking for open-source alternatives, there are several. One of the most visible options is MySQL (www.mysql.com).
