What you need for this book

This book was written on the SQL Developer 4.1 tool and the new features provided by Oracle. Though the name has "Developer" in it, the book should be equally useful for developers, DBAs, and architects. All the examples and features should work with version 4.1, which can be downloaded for free from the OTN website. We need minimum JDK 1.8 to use the SQL Developer 4.1 version.
