David M. Kroenke entered the computing profession as a summer intern at the RAND Corporation in 1967. Since then, his career has spanned education, industry, consulting, and publishing.

He has taught at the University of Washington, Colorado State University, and Seattle University. Over the years, he has led dozens of teaching seminars for college professors. In 1991 the International Association of Information Systems named him Computer Educator of the Year.

In industry, Kroenke has worked for the U.S. Air Force and Boeing Computer Services, and he was a principal in the startup of three companies. He was also vice presi- dent of product marketing and development for the Microrim Corporation and was chief technologist for the database division of Wall Data, Inc. He is the father of the semantic object data model. Kroenke's consulting clients include IBM Corporation, Microsoft, Computer Sciences Corporation, and numerous other companies and organizations.

His text Database Processing: Fundamentals, Design, and Implementation, first pub- lished in 1977, is now in its 14th edition (coauthored with David Auer for the 11th, 12th, 13th, and 14th editions). He introduced Database Concepts (now in the eighth edition that you are reading) in 2003. Kroenke has published many other textbooks, including the clas- sic Business Computer Systems (1981). Recently, he has authored Using MIS (8th edition), Experiencing MIS (6th edition), MIS Essentials (4th edition), Processes, Systems and Information: An Introduction to MIS (2nd edition) (coauthored with Earl McKinney), and Essentials of Processes, Systems and Information (coauthored with Earl McKinney).

An avid sailor, Kroenke also wrote Know Your Boat: The Guide to Everything That Makes Your Boat Work. Kroenke lives in Seattle, Washington. He is married and has two children and three grandchildren.

Scott L. Vandenberg has been on the Computer Science faculty at Siena College since 1993, where he regularly teaches three different database courses at several levels to both computer science and business majors. Prior to arriving at Siena, he taught undergraduate and graduate courses in database systems at the University of Massachusetts-Amherst. Since arriving at Siena, he also taught graduate and undergraduate database courses at the University of Washington-Seattle. He has developed five different database courses over this time. His other teaching experience includes introductory computer science, introduc- tory programming, data structures, management information systems, and three years teaching Siena's required interdisciplinary freshman writing course.

Vandenberg's recent research publications are mainly in the areas of computer science education and data science applications, with earlier work on query optimization and alge- braic query languages. He holds a bachelor's degree in mathematics and computer science from Cornell University and master's and PhD degrees in computer science from the University of Wisconsin-Madison. Medieval history and playing hockey are two things that can tear him away from a database. Vandenberg lives in Averill Park, NY, with his wife, Kristin, and two children.
