Abstract
There is provided, in a computer processing system, an apparatus for managing object data. The apparatus includes a changed objects manager for creating and managing a changed objects list that at least identifies the objects that have changed based on time of change. The changed objects list is associated with a plurality of time buckets. Each of the plurality of time buckets is associated with a respective date and time period and with object change records for objects having a timestamp falling within the respective date and time period. Each of the object change records is associated with a unique object identifier and the timestamp for a corresponding one of the objects. The timestamp specifies a date and a time corresponding to a latest one of a creation time or a most recent update time for the corresponding one of the objects.
