MDM Trust Framework and Confidence Scoring 3

Question 1

What is the effect of setting a high decay rate for a source system's trust configuration in Informatica MDM?

Accepted Answer

The trust score will decrease more rapidly as time passes without a data refresh

Answer

A high decay rate causes the trust score for data from that source to decrease more rapidly over time, making older stale data from that source less likely to survive in the golden record.

Question 2

When Override is set to TRUE for a source system column trust configuration, what is the expected behavior?

Accepted Answer

Data from this source will always overwrite the existing golden record value regardless of trust scores

Answer

When Override is TRUE, data from that source system replaces the existing golden record value regardless of whether its trust score is higher or lower than the current surviving value.

Question 3

What is the practical benefit of Trust Score Decay in real-world Informatica MDM implementations?

Accepted Answer

To reduce the influence of stale source data on the golden record over time

Answer

Trust Score Decay reduces the trust score of data that has not been refreshed recently, ensuring stale source data has decreasing influence on the golden record as time passes.

Question 4

Which Informatica MDM feature allows data stewards to manually override the trust-based survivorship result for a specific field on the golden record?

Accepted Answer

Manual value pinning through Informatica Data Director (IDD)

Answer

Informatica Data Director (IDD) allows data stewards to manually pin a specific value to the golden record, overriding the system-calculated trust-based survivorship result.

Question 5

What is the primary advantage of the Trust Framework over a simple 'last-write-wins' survivorship strategy in Informatica MDM?

Accepted Answer

It allows multiple source systems to contribute field values based on their configured reliability

Answer

The Trust Framework enables field-level survivorship based on each source system's reliability configuration, ensuring the most trustworthy data from any contributing source wins rather than always defaulting to the most recent update.
