Trang 10I would like to thank my wife Sarita for being supportive and doing the major work
of maintaining the household while I was busy with the book revision work My kids Toozy, Ritzy, and Himnish also deserve acknowledgments here for being co-operative and patient with me Special thanks go to the readers of the first edition— especially the ones who have taken time to give their valuable feedback The feedback coming in through various channels has actually inspired me to revise the first edition
to this new edition in line with the release of SQL Server 2008 R2 In the process of writing and editing the book, technical editor Allan Mitchell has contributed his ideas and constructive comments that not only have helped to remove some of the mistakes
in the compilation but also have greatly improved the content I would like to thank all my colleagues at Avis-Europe, where I learn most while working with them and for giving their valuable inputs as well Finally, special thanks to the team at McGraw-Hill for their hard work and support during this project
