"OpenSQL Camp is a free conference of, by, and for the open-source database community of users and developers. The first OpenSQLCamp 2008 took place in Charlottesville, Virginia, USA, November 14, 15, and 16 2008.
The OpenSQLCamp 2009, European Edition will take part in parallel to the Free and Open Source Conference 2009 (FrOSCon) on Saturday 22nd and Sunday 23rd August in St. Augustin, Germany. St. Augustin is located close to Bonn and Cologne.
Attendees of this conference are mostly open source developers and end users/open source enthusiasts. The FrOSCon organizers agreed to provide us with a "Developer Room" for both days, which allows us to organize our own subconference about Open Source Databases and related technologies. The goal of this event is to spread the word about the vibrant communities and large ecosystems around Open Source Databases and to educate the attendees about what alternatives exist to commercial databases. It is a place where people come to learn, to participate and to contribute. In other words, it's a great conference, and if you attend, it will be better. "
