Abstract
A method and system for determining a conflict in a database transaction processing system between a specific transaction and one or more other transactions utilizes a certification system (30). The certification system (30) comprises a memory (32) which contains a log of database activity. The log is periodically broadcast over a channel (42) to a plurality of filters (43) which determine if there are conflicts between particular transactions. The inventive system and method perform optimistic concurrency control in a database transaction processing system in a highly efficient manner.
