ABSTRACT:
The present invention provides a change log handler than can accommodate a change log having an entry that includes more than one modification operation or multi-valued attributes. The change log handler typically includes a change parser for parsing change attributes corresponding to the change log that identify changes to the first data source. Such changes can include a plurality of modification operations as reflected in a single entry of the change log. The change log handler also includes a change reflector for applying the changes to a second data source.
