MDM Data Modeling & Master Data Architecture 5

Question 1

In Informatica MDM, which process determines the final attribute values of the golden record by selecting among competing source system values?

Accepted Answer

Survivorship

Answer

Survivorship rules evaluate competing attribute values from multiple source systems and select the best value based on trust scores, recency, or custom logic.

Question 2

Which Informatica MDM feature allows a data model to support multiple entity types (e.g., Person and Organization) under a single base object using a type discriminator?

Accepted Answer

Subtype modeling using a base object with a record type column

Answer

Subtype modeling uses a single base object with a discriminator column (e.g., PARTY_TYPE) to distinguish between entity types, reducing model complexity.

Question 3

What is the risk of setting match thresholds too low in an Informatica MDM match configuration?

Accepted Answer

Increased false positives — non-duplicate records are incorrectly merged

Answer

Setting match thresholds too low increases false positives, causing distinct records to be incorrectly identified as duplicates and merged.

Question 4

In Informatica MDM, what does the 'source system' configuration in Hub Console primarily define?

Accepted Answer

The trusted source of each attribute and the contribution rules for that system's data in the hub

Answer

Source system configuration defines the system's trust level, contribution rules, and how its data interacts with other systems' records during consolidation.

Question 5

Which normalization strategy is typically AVOIDED in MDM base object design because it hinders match performance?

Accepted Answer

Storing names as a single full-name field instead of first/last components

Answer

Storing a full name as a single concatenated field prevents effective tokenization and fuzzy matching on individual name components.
