Hugh Darwen is a computer scientist who was an employee of IBM United Kingdom from 1967[1] to 2004, and has been involved in the development of the relational model.[2]
Work
From 1978 to 1982 he was a chief architect on Business System 12, a database management system that faithfully embraced the principles of the relational model.[3] He works closely with Christopher J. Date and represented IBM at the ISOSQL committees (JTC1 SC32 WG3 Database languages,[4] WG4 SQL/MM[5]) until his retirement from IBM. Darwen is the author of The Askew Wall[6] and co-author of The Third Manifesto, a proposal for serving object-oriented programs with purely relational databases without compromising either side and getting the best of both worlds, arguably even better than with so-called object-oriented databases.[7]
From 2004 to 2013 he lectured on relational databases at the Department of Computer Science, University of Warwick (UK),[8] and from 1989 to 2014 was a tutor and consultant for the Open University (UK)[9] where he was awarded a MUniv honorary degree for academic and scholarly distinction.[10] He was also awarded a DTech (Doctor in Technology) honorary degree by the University of Wolverhampton.[11] He currently teaches a database language designed by Chris Date and himself called Tutorial D.[12]
Bridge
He has written a book on the card game bridge and has a website on the subject of double dummy problems. Alan Truscott has called him "the world's leading authority" on composed bridge problems.[13] He was responsible for the double dummy column in Bridge Magazine from 1965 to 1990.
Publications
His early works were published under the pseudonym of Andrew Warden: both names are anagrams of his surname.[clarification needed]
