28 Preface

Special thanks to the Teradata University Network and especially to Hugh Watson,
Michael Goul, and Susan Baxley, Program Director, for their encouragement to tie this
book with TUN and for providing useful material for the book.
Many individuals helped us with administrative matters and editing, proofreading,
and preparation. The project began with Jack Repcheck (a former Macmillan editor), who
initiated this project with the support of Hank Lucas (New York University). Judy Lang
collaborated with all of us, provided editing, and guided us during the entire project
through the eighth edition.
Finally, the Pearson team is to be commended: Executive Editor Bob Horan, who
orchestrated this project; Kitty Jarrett, who copyedited the manuscript; and the produc-
tion team, Tom Benfatti at Pearson, George and staff at Integra Software Services, who
transformed the manuscript into a book.
We would like to thank all these individuals and corporations. Without their help,
the creation of this book would not have been possible. Ramesh and Dursun want to
specifically acknowledge the contributions of previous coauthors Janine Aronson, David
King, and T. P. Liang, whose original contributions constitute significant components of
the book.

Note that Web site URLs are dynamic. As this book went to press, we verified that all the cited Web sites were
active and valid. Web sites to which we refer in the text sometimes change or are discontinued because compa-
nies change names, are bought or sold, merge, or fail. Sometimes Web sites are down for maintenance, repair,
or redesign. Most organizations have dropped the initial “www” designation for their sites, but some still use
it. If you have a problem connecting to a Web site that we mention, please be patient and simply run a Web
search to try to identify the new site. Most times, the new site can be found quickly. Some sites also require a
free registration before allowing you to see the content. We apologize in advance for this inconvenience.
