About us

Dave Voorhis

This Web site and Rel are maintained by Dave Voorhis.

After graduating in 1986 with a Bachelor’s degree in Computer Science from Brandon University, Dave Voorhis became a founding partner in a small Canadian software development firm, where he developed specialised database engines in C and C++ to support bespoke business application development. From 2003 to 2019, he was a senior lecturer in Computing and programme leader for BSc. (Hons) Computer Science at the University of Derby.

In June 2019, Dave retired from academia to return to his entrepreneurial roots. He is now an independent software developer, focusing on creating advanced data management applications and bespoke database-driven software.

Dave has continuously developed and refined Rel since its first release in 2004. Dave is also an avid motorcyclist, amateur photographer and musician, and collector of vintage Tektronix oscilloscopes.

Rel would not have been possible without the valuable contributions of various others, including:

Hugh Darwen and Chris Date for The Third Manifesto and Tutorial D. Special thanks to Hugh Darwen for extensive reviews of Rel and helpful comments and encouragement.
