My special thanks go to my better half, Anjali, for putting up with the long, arduous hours that were added to my already swamped schedule; our 8 year old son, Vedant, who tracked my progress on a daily basis; InfoObjects' CTO and my business partner, Sudhir Jangir, for leading the big data effort in the company; Helma Zargarian, Yogesh Chandani, Animesh Chauhan, and Katie Nelson for running operations skillfully so that I could focus on this book; and our internal review team, especially Arivoli Tirouvingadame, Lalit Shravage, and Sanjay Shroff, for helping with the review. I could not have written without your support. I would also like to thank Marcel Izumi for putting together amazing graphics.
