Abstract: A method, system, and computer program product for source record management for master data are provided in the illustrative embodiments. A set of data records is received from a set of data sources. A first subset of data records received from a first data source is pre-processed. A match engine is requested to match a data record from the first subset using at least one record in the master data repository, the requesting resulting in a set of matched data records. The set of matched data records, which includes a first data record in the first subset and a second data record in a second subset, is post-processed. The second subset is received from a second data source. The first data record is assigned to a group of records, together representing the entity as a master data record.
