A master data management system includes a data store. The system includes a data registry to provide storage at the data store of a data record. The data registry maintains a link between the data record and a first source record and between the data record and a second source record. The system includes a data channel associated with each source record, the data channel identifying a change at the data record. Each data channel is associated with an interface process module to update the corresponding source record using an Internet protocol when the associated data channel identifies a change at the data record.
