This book would not have been possible without the contribution of many people who were involved directly or indirectly in the production of the book.

Firstly, we would like to thank the Oracle interMedia engineering team in Nashua, New Hampshire USA, especially the Engineering manager, Susan Mavris, for her extensive review and comments on the manuscript, and Mike Turnill, Oracle UK, and Thames Valley University, and Dr. Samia Oussena for very thoroughly reviewing large sections of the manuscript. Also, thanks to Professor Andy Smith for his support and encouragement.

Finally, we are grateful to everyone at Digital Press for all their encouragement and work.
