• JavaFX db4o example: Jos Koenen just reported that an example of db4o underJavaFX is working just fine. Don't miss this opportunity to check JavaFX persistence with db4o (source code included). Although this is a basic example you might want to contribute more advanced examples based on this one.
• Abstracting Data Access: db4o example: I just run into a nice blog post by Nail Martin ("Prototyping : New wine, old skins") where he shows how to abstract data access with db4o as the underlying persistence engine (Nail is a big fan of repositories and finders, updaters and basically any technique to abstract data access and easily Mock the data layer). Source code is included (C#) and a brief explanation on how to inject the repository against the IoC framework Unity.
