Query: Only Useful as Reference

Perhaps I underrate this book as it might really be useful as a reference. But I am just a run-of-the-mill DBA. What I look for when a new Oracle version is out is a book that explains the new features in a readable fashion and that makes me understand anything required to pass the OCP exam (which is more than I will ever need in real life as the Oracle RDBMS is increasingly blown up with unnecessary features). This book is not a book that one would like to read cover to cover: it is very much written in the stile of the official Oracle documentation, constantly listing parameters over whole pages. This could be useful if you want to drill down into a certain feature, but in such a case you might want to turn to the online documentation anyhow. And you should have read an Oracle 10 New Features book that really made you understand the big picture beforehand.
