I would like to thank and appreciate my son, Saket Saxena, for all the energy and effort that he has put into becoming a diligent, disciplined, and a well-managed 10 year old self-studying kid over last 6 months, which actually was a blessing that enabled me to focus and invest time into the writing and shaping of this book. A sincere word of thanks to Impetus and all my mentors who gave me a chance to innovate and learn as a part of a Big Data group.
