Query: Many errors in text

Palinski is full of errors, confusing and sometimes contradictory explanations. It seems to have been written by someone who is unfamiliar with Oracle, and just blindly compiled material from different sources.I had to check every topic by referring to other documents and manuals.In the beginning, you see this book is like college text, not for working Oracle person. I have more than 15 years experience in Oracle and did not find it useful.
