Review on Amazon.com about the "The Definitive Guide to db4o"
Great book for anyone thinking about using an
object database. Db4o is an awesome database to use for your projects.
This books is a great way to get yourself in the game. The only thing
is that the book is written for version 5.2 and 5.7 is already
available for download and the new stuff in 5.7 isn't in the book.
