This is the first book on Oracle 10g New Features that was out from Oracle Press. It only gives a condensed overview of the topic, so for OCP exam preparation or for a deeper coverage of the new features you should rather turn to Sam R. Alapati's book. I would recommend Freeman's book as a supplement to Alapati as it covers some features which are not part of the OCP exam. It also contains some very useful comments by Jonatan Lewis. As usual for books like this the binding is so poor, that my copy started to fall apart after I read a few chapters.
