System and method for metadirectory differential updates among constituent heterogeneous data sources

摘要

A system and method which propagates change operations to data items within a metadirectory on a differential basis in order to minimize or eliminate redundant updates to attributes within data items that have not changed, as well as conserve computing resources and transmission bandwidth consumed by update activities in large organizations of data items. A best match entry in the metadirectory is selected using a weighted score process, a determination is made as to exactly which attributes are changed by the update operation, and a differential update is propagated throughout the metadirectory via direct joiner access to the data items, or through remote access such as through LDAP.
