Matching objects using keys based on match rules

A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:

• generate a match rule key based on a match rule, wherein the match rule specifies whether two objects match;
• create a plurality of candidate keys by applying the match rule key to a plurality of data objects;
• create a probe key by applying the match rule key to a probe object;
• determine whether the probe key matches a candidate key of the plurality of candidate keys;
• determine whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object in response to a determination that the probe key matches the candidate key corresponding to the candidate object;
• and
• identify the probe object and the candidate object as matching based on the match rule in response to a determination that the probe object matches the candidate object.

A method for matching objects using keys based on match rules, the method comprising:

• generating a match rule key based on a match rule, wherein the match rule specifies whether two objects match;
• creating a plurality of candidate keys by applying the match rule key to a plurality of data objects;
• creating a probe key by applying the match rule key to a probe object;
• determining whether the probe key matches a candidate key of the plurality of candidate keys;
• determining whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object in response to a determination that the probe key matches the candidate key corresponding to the candidate object;
• and
• identifying the probe object and the candidate object as matching based on the match rule in response to a determination that the probe object matches the candidate object.
