[edit] 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.[2] He works closely with Christopher J. Date and represented IBM at the ISO SQL committees (JTC1 SC32 WG3 Database languages,[3] WG4 SQL/MM[4]) until his retirement from IBM. Darwen is co-author of The Third Manifesto.
As of 2011, he lectures on Relational Databases at the Department of Computer Science, University of Warwick (UK),[5] and is a tutor for the Open University (UK)[6] where he was awarded a MUniv honorary degree for academic and scholarly distinction[7] He currently teaches a data sublanguage designed by Chris Date and himself called Tutorial D.[8]
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.[9]

His early works were published under the pseudonym of Andrew Warden: both names are anagrams of his surname.
