ABSTRACT:
A failure rate independent system for achieving zero defect data integrity in a computer transaction system is disclosed. The system receives events from an event generator and stores the raw events to disk. Structural information relating events to transactions is not stored on disk. Data which is lost after a system failure is reconstructed from the raw events during recovery. Transaction processing capacity is increased by trading off the continual updating of disk stored events and associated structural information for the post recovery reconstruction of structural information. As a result, zero defect data integrity is achieved at minimum processing cost.
