To determine records that are duplicates, that is, matches of each other, the MDM Hub uses match rules. You configure match rules for records in base objects. You can define a match rule for exact or fuzzy matching. An exact match rule matches records that have identical values in match columns. A fuzzy match rule matches similar records based on probabilistic match determinations that consider likely variations in data patterns, such as misspellings, transpositions, omissions, and phonetic variations. The match rules that you configure depend on the characteristics of the data, and the particular match and merge requirements.

The match rules configuration example walks you through the configuration process in a step-by-step manner. The example is based on the Party base object data that is available in the MDM Hub sample ORS. The example shows you how to configure match rules for data of individuals in the Party base object to match and merge data based on names and addresses. To view the preconfigured match rules that are similar to the match rules described in the example, set up the MDM Hub sample ORS.
