A host enterprise includes a local data store, a data registry, and an interface process module. The data registry establishes storage of a data record at the local data store or at a data store located remotely from the host enterprise. The data registry maintains links identifying a relationship between the data record and a first source record maintained at a first source enterprise between the data record and a second source record maintained at a second source enterprise. The interface process module determines that a value at the data record has been updated and provides the updated value to the first source enterprise using an Internet protocol.
