Patent ID: 7783591

Claim:
A system comprising: a plurality of heterogeneous data subsystems maintaining stored local data; and a coordinator subsystem configured to maintain stored global data mapped from the local data, the global data including a plurality of global data relationship views representative of relationships between global data records; wherein one of said heterogeneous data subsystems is configured to initiate a data conversion of at least one local data record included in the local data from an origin data schema to a target data schema and to provide at least one data update message representative of the data conversion to said coordinator subsystem; wherein said coordinator subsystem is configured to receive the at least one data update message and asynchronously propagate the data conversion through to at least a subset of the global relationships views in the global data; wherein the global data relationships views include at least a first global data relationship view representative of a first local data relationship view maintained by the one of the heterogeneous data subsystems configured to initiate the data conversion.
