Method and system for multi-block overlap-detection in a parallel environment without inter-process communication

摘要

Techniques for avoiding duplicate comparisons while comparing customer records to identify linked customer records pertaining to a single customer entity are provided. The techniques include the computer system comparing a first electronic customer record with a second electronic customer record to determine if the first electronic customer record and the second electronic customer record pertain to a single customer entity if the computer system identifies a common blocker key corresponding to a selected blocker from a data field in the first electronic customer record and from a data field in the second electronic customer record and if the computer system does not identify a common blocker key corresponding to an additional lower order blocker from another data field in the first electronic customer record and from a data field in the second electronic customer record.

1. A computer implemented method comprising:
a computer system identifying a target group of electronic customer records, each of the target group of electronic customer records having multiple data fields containing customer data; the computer system identifying a plurality of blockers, each of the plurality of blockers identifying a target data field within the multiple data fields; the computer system identifying a selected blocker and an additional blocker from the plurality of blockers, wherein the additional blocker is of a lower order than the selected blocker; the computer system identifying a first electronic customer record and a second electronic customer record from the target group of electronic customer records; the computer system analyzing the first electronic customer record to identify first potential blocker keys associated with the selected blocker and the additional blocker; the computer system analyzing the second electronic customer record to identify second potential blocker keys associated with the selected blocker and the additional blocker; the computer system comparing the first electronic customer record with the second electronic customer record to determine whether the first electronic customer record and the second electronic customer record pertain to a single customer entity when the computer system identifies a common blocker key corresponding to the selected blocker from the first electronic customer record and from the second electronic customer record and the computer system does not identify a common blocker key corresponding to the additional blocker from the first electronic customer record and from the second electronic customer record; and the computer system not comparing the first electronic customer record with the second electronic customer record to determine whether the first electronic customer record and the second electronic customer record pertain to a single customer entity when the computer system identifies a common blocker key corresponding to the selected blocker from the first electronic customer record and from the second electronic customer record and the computer system also identifies a common blocker key corresponding to the additional blocker from the first electronic customer record and from the second electronic customer record.
