Kristian Wagaan and Richard Hillegas, both Apache Derby committers who also work on Java DB, recently gave some great presentations about Apache Derby and Java DB.

Kristian Wagaan presented at the 2009 OpenSQLCamp, in conjunction with FrOSCon 2009 in Europe.

The presentation (slides) gives a brief overview of Apache Derby, its history and the community around it. Further, it goes into the details of features that have been added in the latest releases and show how they enable powerful ways to use a relational database.

Rick Hillegas gave an introduction of Java DB / Apache Derby at The San Francisco Java User Group's Sep 8th event in San Francisco.
