Data Governance & Stewardship Frameworks Flashcards

What is the primary role of a data steward in a Master Data Management program?

Answer: To maintain data quality, enforce data standards, and resolve data issues within their domain

Data stewards are business-side custodians responsible for the quality, consistency, and governance of master data within their specific domain, acting as the bridge between business requirements and technical implementation.

In Informatica MDM, what is a 'trust score' used for?

Answer: To determine which source system's data values should be used when records from multiple sources are merged

Trust scores in Informatica MDM quantify the reliability of data values from different source systems. During the merge/survivorship process, higher trust scores indicate which values should be retained as the 'golden record.'

What is a 'golden record' in the context of Master Data Management?

Answer: The single, authoritative, and most trusted version of a master data entity

A golden record is the consolidated, best-of-breed version of a master data entity created by merging attributes from multiple source records, representing the single source of truth.

What is the purpose of data profiling in an MDM implementation?

Answer: To analyze existing data to understand its quality, structure, and content before migration

Data profiling examines source data to identify quality issues (duplicates, missing values, inconsistencies), understand data patterns, and plan data cleansing strategies before loading into the MDM hub.

What does 'survivorship' mean in Informatica MDM merge operations?

Answer: The rules that determine which attribute values are retained when multiple records are consolidated into one

Survivorship rules define which field values from overlapping source records will 'survive' into the golden record during consolidation, based on factors like trust scores, recency, and source system priority.

What is the difference between a 'registry style' and a 'consolidation style' MDM implementation?

Answer: Registry keeps data in source systems and maintains references; consolidation copies and merges data into a central hub

A registry style MDM creates a central index that points to data in source systems without copying it, while a consolidation style physically copies and merges data into a central hub to create golden records.
