Once again our recently appointed dVP Edwin Sanchez delivers a great db4o blog post. This time it's about the reasons that may be preventing you from using db4o. It's a great approach to the subject, sometimes developers won't even consider db4o for the wrong reasons!

Check Edwin's last point: Why don't you tell a friend or coworker about db4o? =)
Enjoy (thx Edwin)!
