First, I would like to thank Almighty Allah (Subahana wa tala). The people I'd like to thank most for their direct or indirect help in writing this book are my wife and my parents; the rest of my family for their love and support; and my fellow staff and friends who gave me encouragement and support, including Adeel Ansari, Aneel Ansari, Kashif Haseeb, Babar Qadri, and Mobin Khan.

Finally, I'd like to thank my co-author, Talha Haroon, without whom this project wouldn't have been possible.

Talha Haroon initially started working in the HRM and CRM fields as his main areas of focus, but later on in his career path, he dedicatedly moved to MobileFirst. If we glance at his specialities, then it would become apparent that he has proficient expertise in ERP's development and customization as well as mobile hybrid development. He is also IBM Worklight Certified and has deployed and developed many enterprise and mobile applications in which AMEX Mobile app and AppleVacationsOnline.com are the most highlighted and his biggest products. Moreover, he has introduced some futuristic business processes that will assist retail businesses to grow by themselves.

After thanking Allah (subahana wa tala), I am pleased to thank my mother, Fauzia Haroon, who always prays for me and has made me capable enough to raise myself in an upright way. Of course, my special thanks to my co-author, Muhammad Saif Uddin, who played a very crucial role within this project.
