I must admit I had some preconceptions when I picked up this book. I thought it might be a little weak on substance. I also thought it was trying to do too much, with such a broad topic. It turns out I was pleasantly surprised.
For starters I read the preface. The authors work in technical sales, and the target audience is pretty broad, from DBAs & Developers to Systems Administrators and also IT managers and business users. I emphasize this because it is well written to be a good introductory Oracle book for DBAs and Developers, and not too technical that these other audiences can't digest the material. More importantly it is very well written. The style is quite good. I guess that's no surprise, being that the book is in it's fourth printing.
I like the first chapter, Introducing Oracle, as it takes a stab at not only some of the history of the company, but the technology as well. I learned a few things along the way. It includes a "Summary of Oracle Database Features" which is broad and all encompassing. Sure you could probably find all of this in the documentation... somewhere! However, having it all summarized is very nice. Development Features, Connection Features, App Server, Distributed Features, Data Movement Features, Performance Features, Management Features, Backup Features, Availability Features, Security Features, and so on.
Chapter two covers the Oracle Architecture, nuts & bolts, chapter three installation, Chapter four data structures, chapter five management, chapter six security, seven performance, eight concurrency, nine transactions, ten warehousing, eleven high availability, twelve various hardware architectures, thirteen distributed db, fourteen extended datatypes, and fifteen beyond the database.
As I was flipping through the chapters, I was also looking for an easy way to find the 11g features. I guess I was thinking more along the lines of a New Features book, which this is not. However the book does include Appendix A, which clearly lists all the new stuff in Oracle 11g, so that fit the bill.
Overall it was a very comfortable read and enjoyable. Even if you are quite technical, you will surely learn something new as the broad spectrum of Oracle is so wide, that there are surely things you're not well familiar with. However it is primarily targeted to folks new to the Oracle world, who want to dip their toes in, and learn about the family of products. And for that I would really recommend it.

This book is well written and organized. It provides a comprehensive overview of Oracle features and technologies, including the latest Oracle database 11g for begineers. The focus is on principles rather than syntax, such as Oracle security & auditing, performance, multiuser concurrency, transaction processing and high availability.

The 4th updated edition of ORACLE ESSENTIALS is a must for any library strong in databases in general and Oracle in particular, offering an easily-read reference packed with tips on data structures, installation, networking, and customization processes. Features beyond the Oracle database: Express, Fusion Middleware, and more - compliment specifics on the latest Oracle Database 11g, providing a comprehensive reference for new and old users alike!

Oracle Essentials, Oracle Database 11g, 4th edition
Rick Greenwald et al.
O'Reilly - 4th Edition (11g)
http://www.oreilly.com/catalog/9780596514549/index.html
This is a very detailed overview of the inner workings of Oracle. Each chapter is a small book in itself going into the detail of the subject. This might be confusing to those without a clear understanding of how databases work in general, and a background in computer science would help. Overall, the author does a nice job of explaining each topic in such a way that it would be reasonably clear either way though. There are many diagrams, tables, lists, and pictures to help explain the material. This would not be so much a reference for programming Oracle as it explains what is available in Oracle and how Oracle provides its features. The book should be usefully to Oracle DBAs and system administrators. It will also appeal to those that want a book that goes beyond stating what Oracle can do and shows how Oracle actually does what it can do.
Generally chapters cover:
Overview
Architecture
Installation and Running
Data Structures (B*-trees, etc.)
Management
Security
Performance
Concurrency
Transactions
Warehousing, Business Intelligence
Availability
Hardware
Distributed Databases
Object Oriented Development
New Features of 11g
Summary:
- The internal workings of Oracle are clearly explained through out.
- A great book for system administrator, DBAs, and those who take care of Oracle databases.

This book is for people of all levels of Oracle experience and includes database administrators, system administrators, and application developers. Even though there is some introductory material that more experienced people might be tempted to skip over, it is probably best to go through the book from beginning to end just to make sure you don't miss some minute point of Oracle. It does not try to teach database theory, though. You need to be familiar with that in a general sense before you read this book.
The main purpose of this fourth edition is to add information relevant to the newest release, Oracle Database 11g. Appendix A is handy in that it contains, in a condensed form, what is new for 11g. The book manage to concentrate on the most important Oracle issues and principles. It isn't possible to write one book that encompasses everything about Oracle, particularly syntax details, so you'll need to refer to Oracle documentation for complete details.
