(1) A point in time when data is considered to be consistent. See also synchronization point.
(2) The point at which an application program commits that a section of work is done and that the data it has modified or created is consistent and complete. The application program's output, which has been held up to that time, is sent to its destinations, its input is removed from the message queues, and its database updates are confirmed and made available to other applications. A commit point occurs when a program terminates normally or when it issues a checkpoint call or command. If a program processes messages, a commit point may also occur when it retrieves a new message.
