James Nicholas "Jim" Gray (born 1944, lost at sea January 28, 2007) was an Americanmarker computer scientist who received the Turing Award in 1998 "for seminal contributions to database and transaction processing research and technical leadership in system implementation."


Gray studied at the University of California, Berkeleymarker, where he earned his B.S. in Engineering Mathematics (Math and Statistics) in 1966 and his Ph.D. in Computer Science in 1969. He was the first recipient of a Ph.D. from Berkeley's Computer Science Department.

Gray pursued his career primarily working as a researcher and software designer at a number of industrial companies, including IBM, Tandem Computers, and DEC. He was a Technical Fellow for Microsoft Research in San Francisco, beginning in 1995.


Gray contributed to several major database and transaction processing systems, including the System R while at IBM, TerraServer-USA and Skyserver for Microsoft. Among his best known achievements are granular database locking, two-tier transaction commit semantics, the "five-minute rule" for allocating storage, and the data cube operator for data warehousing applications. He assisted in the development of Virtual Earth. He was also one of the cofounders of the CIDR conference.

Disappearance at sea and search

During a short solo sailing trip to the Farallon Islandsmarker near San Franciscomarker to scatter his mother's ashes, his 40-foot yacht, Tenacious, was reported missing on Sunday, January 28, 2007. The Coast Guard searched for four days using a C-130 plane, helicopters, and patrol boats but found no sign of the vessel.

However, Gray's boat was equipped with an automatically deployable EPIRB (Emergency Position-Indicating Radio Beacon), which should have deployed and begun transmitting the instant his vessel sank. The area around the Farallon Islands where Gray was sailing is also well north of the East-West ship channel used by freighters entering and leaving San Francisco Baymarker. The weather was clear that day and no ships reported striking his boat, nor were any distress radio transmissions reported.

On February 1, 2007, the DigitalGlobe satellite did a scan of the area, generating thousands of images. The images were posted to Amazon Mechanical Turk in order to distribute the work of searching through them, in hopes of spotting his boat.

On February 16, 2007, the Friends of Jim Gray Group suspended their search, but continue to follow any important leads. The family ended its search May 31, 2007. The massive high-tech effort did not reveal any new clues.

The University of California, Berkeleymarker hosted a tribute to Gray and his life on May 31, 2008. The conference included sessions delivered by Richard Rashid and David Vaskevitch. Microsoft's WorldWide Telescope software is dedicated to Gray. In 2008, Microsoft announced the opening of a research center in Madison, Wisconsinmarker, to be named after Jim Gray.
