Hi!
There's a project for porting db4o (it's an open source object database) to Ruby called db4ro (http://developer.db4o.com/ ProjectSpaces/view.aspx/Tools_And_Add-Ons/ Language_Bindings_or_Implementations). I wonder whether this could be a nice addition to Rails or ActiveRecord is more than enough. What do you think? Has anyone tried db4o?
Best regards and thanks for your input.
