Query: Not a book for beginners

I have read the first 5 chapters of this text and I can't believe they are marketing this text at beginners. If I was a beginner I would get absolutely nothing out of this book. I am not a beginner and it still offers nothing of value in the first 5 chapters. It uses database-related terms before they are ever defined and then when they are defined the reader is left with the feeling - "What did that mean?". The examples are not well developed and add nothing to the text. I am surprised that the publisher did not have some "beginners" read this text and comment. I do not have the stamina to finish the book.
