Without a second thought, I would like to dedicate this book to my mother for taking all the pain of my childhood and making me capable enough to write a book, which is something wonderful to happen in anybody's life. I would also like to thank my wife, Swati, for providing suggestions while writing the book. A large share of this book goes out to all my students who took Informatica training from me, which gave me the ability and motivation to write a book to help all those who I cannot reach out to personally. This also calls for a thank you note to all the reviewers of the book for pointing out the mistakes that I made while writing and providing valuable suggestions—as we say, no one is perfect.

Also, a special thanks to Packt Publishing for giving me the opportunity to write this book and for showing confidence in my writing. A big thanks to the readers of the book. I hope you will like it and make a bright career in Informatica.

I wish you all the luck for future. Keep smiling, make others smile, and make our mother earth a better place to live.
