Query: Unorganized, poorly written.

I found this books useless. There is much better books out there, even if you are a new beginner. In this book there is not any word about Java infrastructure of Oracle 8i, which is the main difference between Oracle 8i and Oracle 8. On the other hand, it tries to explain you some java related tools. No figures, charts or graphis of any sort to make the understanding easier. I could not find any correlation about how the authors organized the chapters and the chapters' contents. The author's style is very irratating as he continously praises Oracle. Oracle this, Oracle that..etc, without giving a solid information. Shortly this books is bad and do not waste your money. You can find better information in Oracle white papers or documentations which are free at technet.oracle.com and at oracle web site.If you are a new beginner, buy dummies series. Dan Hotka's Oracle Unleashed book is also very good for ever level of readers.
