O’Reilly Media will be hosting the MySQL Conference in Santa Clara, California: April 12 - 15, 2010.
While this group is ostensibly about a fantastically popular relational database and how we use it, meeting topics cover a lot of ground. In attendance is almost always an actual developer of the database with a laptop and a copy of the source code, in case some difficult question comes up.
If you work with MySQL regularly and need a book on the topic with an easy to follow writing style and helpful examples, please consider buying MySQL in a Nutshell. If you already have the first edition, the second edition recently came out: it’s much better than the first edition and has had some great reviews.
