I thank my family for their patience and understanding as I took time away from them to write this book. I thank my wife for taking the frontline parent job. The book is finished, and I’m back.

I thank my friends and colleagues for their help and contributions. Thank you to Brent Moser and Kishore Nagururu for your reviews and comments. I am grateful for your constructive criticism and patient guidance. Thank you to Dan Taylor and Pierre Guerrero for your help and direction in the database designs. Thank you to Sara Yeager and Ken Graham for explaining to me what I’d discovered. Let’s do lunch again.

I thank God for making this book a reality. This has been a long journey of discovery, for which I am grateful. I thank Jack Rader, who gave me my first job. I thank Steve Olive, who taught me how to do my first job. Without their help, and the help of so many others, I would have accomplished nothing.

Finally, I thank Auerbach Publications for allowing me the opportunity to publish a second book.
