Query: Very disappointed in this book

This book is terrible. It doesn't read like a book - it is simply a list of terse definitions of various database topics.Based on the Table of Contents, I was really looking forward to learning about data blocks, segments, extents, tablespaces, views, indexes, triggers, constraints, cursors, etc., when I bought this book. Unfortunately, this book was too confusing and poorly written to learn anything.I mean no disrespect to Mr. Romalho, but the fact that English is not his primary language is probably why the book reads so choppy.If anyone can recommend a book to me that covers the topics I previously mentioned, please email me at: stevenardone@hotmail.com.
