Negative Positive
Title: Very handy
Review: This book now lives permanently in my laptop bag (despite how heavy it is). Tom really goes out of his way to show you why you should do things certain ways, and he proves what he's saying through every part of the book with actual test cases. Applying some of the concepts from this book gave my application a 4x's performance boost, so my customers are much happier already. The biggest things you learn are to benchmark everything and not to assume anything about Oracle without testing it. The book really opened my eyes and made me realize as an application developer how much I was guessing about Oracle without actually knowing.
Is the review positive or negative?
