Jonathan has over seven years of experience working with relational database technology, and is currently the lead database administrator for the utilities group working out of KPMG's Detroit office. In his day-to-day work as a DBA, Jonathan has come to depend heavily on SQL*Plus, and uses it extensively. When he is not managing databases, Jonathan can often be found writing or editing books about them. His writing career began in 1997, when he coauthored Teach Yourself PL/SQL in 21 Days (Sams). Since then, he has been involved with four other book projects. He was the technical editor for Oracle8 Server Unleashed (Sams), the development editor for Teach Yourself Access 2000 in 24 Hours (Sams), a technical reviewer for Oracle Database Administration: The Essential Reference (O'Reilly & Associates), and the author of the book you are holding now. Jonathan is a member of MENSA, and he holds a bachelor of arts degree in Information and Computer Science from Andrews University in Berrien Springs, Michigan. Jonathan currently resides in Lansing, Michigan, with his wife Donna and their two children: ten-year-old Jenny, who often wishes her father wouldn't spend quite so much time writing, and three-year-old Jeff, who has never seen it any other way. Jonathan may be contacted by email at jonathan@gennick.com. Colophon The animal on the cover of Oracle SQL*Plus: The Definitive Guide is a moving leaf (Phyllium giganteum), a large (about 10 cm in length) Malaysian leaf insect related to stick insects; together these constitute the order Phasmalida, derived from the Greek word for ghost. These stunning insects imitate local foliage with intricate detail, down to the leaf-like veins on their legs and tattered brown edges to mimic dead leaves. Moving leaf insects feed on bramble and other plant material. Kept by many entymologists as exotic pets, they require high temperature and humidity. Ellie Fountain Maden was the production editor and project manager for Oracle SQL*Plus: The Definitive Guide, and also copyedited the book. Quality assurance was provided by Madeleine Newell, Sarah Jane Shangraw, and Sheryl Avruch, who was also the production manager. Ellie Cutler proofread the book, and Seth Maislin wrote the index. < previous page page_503 next page > < previous page page_504 Page 504 Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. The cover layout was produced by Kathleen Wilson with Quark XPress 3.32 using the ITC Garamond font. The inside layout was designed by Nancy Priest and implemented in FrameMaker 5.5 by Mike Sierra. The text and heading fonts are ITC Garamond Light and Garamond Book. The illustrations that appear in the book were created in Macromedia FreeHand 8 and Adobe Photoshop 5 by Robert Romano. This colophon was written by Nancy Kotary. Whenever possible, our books use RepKover, a durable and flexible lay-flat binding. If the page count exceeds RepKover's limit, perfect binding is used. < previous page page_504 . jonathan@gennick.com.
