  1. In Informatica MDM Hub, what does a trust score determine?

    Answer: The reliability of a source system's contributed value when populating a golden record field

    Trust scores represent the configured reliability of a source system's data for a specific column, controlling which source value wins in the golden record.

  2. Which MDM Hub match type compares two records using phonetic, edit-distance, or other approximate algorithms?

    Answer: Fuzzy match

    Fuzzy matching uses probabilistic algorithms like Jaro-Winkler or Soundex to find records that are similar but not identical, catching typos and variations.

  3. What is the purpose of a 'match rule set' in MDM Hub?

    Answer: A collection of individual match rules evaluated together to determine if two records should be merged

    A match rule set groups related match rules and applies them sequentially or in combination to decide whether two candidate records represent the same real-world entity.

  4. In MDM Hub's trust framework, what does 'trust decay' mean?

    Answer: The reduction in a source system's trust score over time as data ages

    Trust decay allows administrators to configure a time-based reduction in trust so that older source values are less likely to overwrite more recent contributions.

  5. When two records are merged in MDM Hub, what happens to their individual cross-reference records?

    Answer: They are retained and linked to the surviving golden record's ROWID_OBJECT

    After a merge, all contributing cross-reference records point to the winning golden record, preserving the lineage of every source system's contribution.

  6. Which Hub Console tool is used to review, accept, or reject match candidates before a merge is finalized?

    Answer: Merge Manager

    Merge Manager provides a UI where data stewards can inspect identified duplicates and decide to merge, link, or reject each match candidate.

  7. What is an 'auto-merge' threshold in MDM Hub match configuration?

    Answer: A minimum match score above which records are merged automatically without human review

    The auto-merge threshold sets the minimum match score at which MDM Hub merges records programmatically, bypassing the manual Merge Manager review queue.
