from Cambridge University (U.K.) in 1962. He entered the computer business as a mathematical programmer at Leo Computers Ltd. (London), where he quickly moved into education and training. In 1966, he earned his Master's degree at Cambridge, and, in 1967, he joined IBM
Hursley (UK) as a programming instructor. Between 1969 and 1974, he was a principal instructor in IBM’s European education program.
While working at IBM
he was involved in technical planning and design for the IBM products SQL/DS
and DB2
.
He was also involved with Edgar F. Codd
’s relational model
for database management.
He left IBM in 1983 and has written extensively of the relational model, in association with Hugh Darwen
.
His book An Introduction to Database Systems, currently in its 8th edition, is widely regarded as one of the fundamental texts on the subject. It has sold well over 700,000 copies not counting translations, and is used by several hundred colleges and universities worldwide.
He is also the author of many other books on data management
, most notably Databases, Types, and the Relational Model, subtitled and commonly referred to as The Third Manifesto
, currently in its third edition (note that earlier editions were titled differently, but maintained the same subtitle), a detailed and sweeping proposal for the future direction of DBMSs.
In recent years he has published articles with Fabian Pascal
at Database Debunkings.
