Summary:1. Field of Invention A deferred transaction mechanism facilitates multi-threaded operation of database application programs. The deferred transaction mechanism allows data items to be committed from the local memory of a computer system to a database system in a background thread, while other foreground threads continue to read the data item. In most instances, this makes the delay in committing a data item to the database imperceptible to a human user of a database application program. The deferred transaction mechanism further supports an "undo" feature, which allows modifications to a data item located in a computer's local memory to be rapidly discarded.
