1998 · Databases
Databases must preserve meaningful changes even when computers crash.
Visual guide
Treat related updates as a unit.
Manage concurrent operations.
Preserve committed changes after failure.
Reliable transaction processing supports the integrity of shared databases, including financial and commercial systems.
Transaction guarantees have a defined scope; choices about isolation, failures and distributed coordination still matter.
01 · The idea
Jim Gray helped establish transaction processing as a rigorous and practical discipline. A transfer between accounts must not leave money removed from one account but absent from the other. Transactions group related changes, coordinate concurrent work and use recovery mechanisms to keep committed results dependable.

02 · The people
Jim Gray made transaction processing a rigorous and practical foundation for reliable databases. He studied how systems can preserve consistent results despite concurrent activity, machine failures, and recovery. His work helped define the properties expected of transactions and the engineering methods needed to deliver them. After research in several industrial laboratories, he joined Microsoft, where he also explored large scientific datasets and data-intensive computing.
