Abstract
A computer processing system that receives sequences of changes to a data base and records them into an activity log for later retrieval also maintains a consistent change data table that contains sufficient change information for each of the changes to the data base such that the changes can be propagated through multiple copies of the data base by consulting the consistent change data table. The consistent change data includes information sufficient to permit reconstruction of the data base to reflect the condition of the data base at any moment of time in the activity log. Because the consistent change data is complete, it permits producing multi-generational copies of data base tables for replication from one copy level to any other subsequent level, or iteration, of copy.
