Research
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 joined Microsoft in 1995 and was a Technical Fellow for the company[a] until he was lost at sea in 2007.[14]
Gray contributed to several major database and transaction processing systems.
His best-known achievements include:
- ACID, an acronym describing the requirements for reliable transaction processing and its software implementation
- Granular database locking[15]
- Two-tier transaction commit semantics
- The Five-minute rule for allocating storage
- OLAP cube operator for data warehousing

Disappearance
Gray, an experienced sailor, owned a 40 foot (12 m) sailboat. On January 28, 2007, he failed to return from a short solo trip to scatter his mother's ashes at the
A four-day
On February 1, 2007, the DigitalGlobe satellite scanned the area[24] and the thousands of images were posted to Amazon Mechanical Turk. Students, colleagues, and friends of Gray, and computer scientists around the world formed a "Jim Gray Group" to study these images for clues. On February 16 this search was suspended,[25] and an underwater search using sophisticated equipment ended May 31.[9][26][27][28][29][30]The
Legacy
Database conference SIGMOD confers the Jim Gray Doctoral Dissertation Award annually to doctoral candidates researching databases.[35]
