Donald D. Chamberlin was born in San Jose, in the USA. After attending Campbell High School he studied engineering at Harvey Mudd College from where he holds a B.S. After graduating he went to Stanford University on an National Science Foundation grant where he studied electrical engineering and minored in computer science. Chamberlin holds a M.Sc and a PhD degree in electrical engineering from Stanford University. After graduating Chamberlin went to work for IBM Research at the Yorktown Heights research facility in New York where he had previously had a summer internship.
Chamberlin is probably best known as co-inventor of SQL (Structured Query Language), the world's most widely-used database language. Developed in the mid-1970s by Chamberlin and Raymond Boyce, SQL was the first commercially successful language for relational databases. Chamberlin also was one of the managers of IBM's System R project, which produced the first SQL implementation and developed much of IBM's relational database technology. System R, together with the Ingres project at U.C. Berkeley, received the ACM Software System Award in 1988. Until his retirement in 2009 he was based at the Almaden Research Center. He was appointed an IBM Fellow in 2003.[1]
In 2000, jointly with Jonathan Robie and Daniela Florescu, he drafted a proposal for an XML query language called Quilt.[1][2] Many ideas from this proposal found their way into the XQuery language specification, which was developed by W3C with Chamberlin as principal editor.[1] XQuery became a W3C Recommendation in January 2007.[3]
Chamberlin is also an ACM Fellow, IEEE Fellow and a member of the National Academy of Engineering. In 2005 he was awarded an honorary doctorate by the University of Zurich.[1] He was awarded the 2009 Fellowship of the Computer Science Museum for his fundamental work on SQL.[4]
In 1988, Chamberlin was awarded the ACM Software Systems Award for his work on System R.[5]
He is currently teaching undergraduate programming at the University of California, Santa Cruz.
He is the author of two books on IBM's DB2 UDB, and more than 50 technical papers.
He contributed a chapter (and the cover photograph) to the 2003 book XQuery from the Experts, ISBN 0321180607.
He has also contributed problems and served as a judge for the ACM International Collegiate Programming Contest for twelve consecutive years (1998–2009).
