MDM Match and Merge Rules 3

Question 1

In Informatica MDM, what is a 'match path component' used for?

Accepted Answer

To specify the relationship traversal path when matching on related entity data

Answer

Match path components define how MDM traverses foreign-key relationships to retrieve related data (e.g., address records) for use in cross-object match column comparisons.

Question 2

Which setting in an Informatica MDM match rule set defines the minimum score a record pair must achieve to be considered a potential duplicate?

Accepted Answer

Match Threshold

Answer

The Match Threshold is the lower bound score; record pairs scoring at or above it are treated as potential duplicates and routed to either auto-merge or manual review.

Question 3

What is the effect of setting a match column's 'Null Match' property to 'Match on Null' in Informatica MDM?

Accepted Answer

Two records both having null in that column are treated as matching on that column

Answer

When 'Match on Null' is configured, two null values in the same match column are treated as equivalent, contributing positively to the match score.

Question 4

In Informatica MDM, what is an 'exclusive match rule'?

Accepted Answer

A rule that, when satisfied, prevents the matched records from being merged regardless of score

Answer

An exclusive match rule, when its criteria are met, excludes the record pair from being merged — useful for records that share attributes but must remain distinct (e.g., same-name family members at the same address).

Question 5

During an Informatica MDM batch match job, what is the purpose of the 'tokenize' stage?

Accepted Answer

To generate match key tokens from record data used to retrieve match candidates

Answer

The tokenize stage generates match key tokens (e.g., phonetic or exact keys) and stores them in match key tables so candidates can be efficiently retrieved during the match stage.
