Abstract: An apparatus, system, and method are disclosed for automatically maintaining identity relationships among disparate enterprise information systems. The apparatus comprises a synchronization hub comprising an identity relationship repository, a relationship service module, a consistency module, and an adjustment module. The relationship service is configured to access a target relationship entry using a unique key from a source business object, wherein the source business object is representative of changes made in a source enterprise information system. The various components and modules of the synchronization hub cooperate to determine identity relationships that need updating and to propagate identity relationship changes to one or more destination enterprise information servers.

Abstract: An apparatus, system, and method are disclosed for synchronizing change histories in enterprise applications. An access module accesses a source data object container provided by a source EIS and a destination data object container provided by a destination EIS. The source data object container comprises a source change history, and the destination data object container comprises a destination change history. A transformation module may retrieve a transformation definition from an integration server, or the transformation definition may be provided in some other fashion. An interpretation module interprets the transformation definition to determine the relationships between the source data object container and the destination data object container. A copy module may copy select portions of the source change history to the destination change history.
