Claim:
1. A method for data management, the method comprising: a computer selecting a first data record and a second data record, wherein one or more attributes of the data records used by a deterministic algorithm are independent of one or more attributes of the data records used by a probabilistic algorithm, and wherein the one or more attributes of the data records used by the deterministic algorithm overlap the one or more attributes of the data records used by the probabilistic algorithm; the computer determining whether the first data record and the second data record share a deterministic matching category, wherein a matching category includes one or more data record types; responsive to determining the first data record does not share a deterministic matching category with the second data record, the computer determining whether the first data record and the second data record share a probabilistic matching category; responsive to determining that the first data record and the second data record share a probabilistic matching category, the computer determining whether one or more additional records in the probabilistic matching category match; the computer setting a comparison score as a number of matching records in the probabilistic matching category; the computer determining whether the comparison score meets or exceeds a predetermined threshold value; responsive to determining that the comparison score meets or exceeds the predetermined threshold value, the computer retrieving matched data records; and subsequent to retrieving matched data records, the computer applying data steward rules to the matched data records, wherein the data steward rules define additional requirements to determine a final match outcome.
