Systems and methods for merging source records in accordance with survivorship rules

According to some embodiments, a plurality of source records may be received from a plurality of data sources, with each source record including a plurality of fields. It may be determined that a match group of source records from different data sources relate to the same entity, and a single best record may be automatically created for the match group based on field values from different source records in the match group. The creating may includes, for example, assigning a first set of fields to a first survivorship group associated with a first survivorship rule and a second set of fields to a second survivorship group associated with a second survivorship rule. All records in the match group may then be simultaneously ranked in accordance with the first and second survivorship rules using a single query. The best record could then be stored for subsequent use by other applications.
