An exemplary system includes a plurality of heterogeneous data subsystems maintaining local data and a coordinator subsystem configured to maintain global data mapped from the local data. The coordinator subsystem includes a global data life cycle model defining at least one life cycle for the global data. The coordinator subsystem is configured to use the global data life cycle model to coordinate a data update between the global data and the local data. In certain implementations, the coordinator subsystem and the heterogeneous data subsystems are configured to communicate using at least one data update message representative of the data update, the data update message being defined in accordance with the global data life cycle model. In certain implementations, the data update message includes a life cycle status identifier associated with the data update.
