According to some embodiments, a plurality of records may be received over a period of time from a plurality of sources. As the records are received during the period of time, master data management may be performed to match at least some records from different sources with each other. A statistics window within the period of time may be determined, and at least one master data management statistics value may be calculated based on the master data management that was performed during the statistics window. The calculated master data management statistics value may then be displayed.
