Sean Dillon started programming a Commodore Vic 20 back in 1980 at the age of 9. As Sean grew, so did his love for programming. He began his professional programming career in the United States Marine Corps, shortly after returning from the Gulf War. Sean is now a principal technologist working for Oracle Corporation based in Reston, Virginia. He has 10 years of experience specializing in database architecture, database tuning, web application development, XML, and web services technologies.
Christopher Beck has a bachelor's degree in computer science from Rutgers University and has been working in the technology industry for 11 years. Starting off as a junior Ada software developer for a government systems integrator, he has spent the past 7 years with Oracle, most recently as a principal technologist. He specializes in core database technologies and web application development. Beck is also a cocreator of Oracle Portal, a commercial product that began as, in Beck's own words, a "science project," then known as WebView.
Thomas Kyte is the vice president of the Core Technologies Group at Oracle Corporation and has been with the company since version 7.0.9 was released in 1993. Kyte, however, has been working with Oracle since version 5.1.5c.
At Oracle, Kyte works with the Oracle database, and more specifically, he helps clients who are using the Oracle database, and works directly with them specifying and building their systems or rebuilding and tuning them. Prior to working at Oracle, Kyte was a systems integrator who built large-scale, heterogeneous databases and applications for military and government clients.
Tom Kyte is the same "Ask Tom" whose column appears in Oracle Magazine, where he answers questions about the Oracle database and tools that developers and DBAs struggle with every day.
