MDM Architecture and Datamodel 3 — Questions and Answers
Question 1: Which MDM Hub concept describes the relationship between a source record and its corresponding golden record in the base object?
- Trust lineage
- Cross-reference (XREF) (Correct answer)
- Survivorship mapping
- Source binding
Correct answer: Cross-reference (XREF)
A cross-reference (XREF) record links each source system record to its corresponding golden master record in the base object, preserving origin traceability.
Question 2: In MDM Hub, what is the purpose of 'Cleanse Functions' applied during the Stage process?
- To execute match rules against staging records
- To standardize, parse, and enrich field values before they enter base objects (Correct answer)
- To calculate trust scores for survivorship
- To merge duplicate records into a single golden record
Correct answer: To standardize, parse, and enrich field values before they enter base objects
Cleanse Functions transform raw source data during staging by standardizing formats, parsing composite fields, and enriching values before matching and consolidation.
Question 3: What is a 'Package' in the context of Informatica MDM Hub Services Integration Framework (SIF)?
- A bundled deployment artifact containing hub configurations
- A named query definition that exposes base object data via SIF APIs (Correct answer)
- A reusable cleanse function library
- A batch job definition for loading data
Correct answer: A named query definition that exposes base object data via SIF APIs
A Package in MDM Hub SIF is a named, predefined query that defines which base object columns and relationships are exposed through the SIF API for reading or writing master data.
Question 4: Which MDM Hub architectural layer is responsible for executing cleanse, match, and merge batch processes?
- Hub Console
- Process Server (Cleanse Match Server) (Correct answer)
- SIF API layer
- Hub Store
Correct answer: Process Server (Cleanse Match Server)
The Process Server (also called Cleanse Match Server) executes the batch cleanse, tokenization, match, and consolidation jobs that produce the golden master records.
Question 5: In MDM Hub's data model, what distinguishes a 'Relationship Base Object' from a standard base object?
- It stores audit history rather than current master records
- It represents many-to-many associations between two base objects using foreign key columns (Correct answer)
- It is used exclusively for hierarchy management
- It cannot have trust and survivorship rules applied to it
Correct answer: It represents many-to-many associations between two base objects using foreign key columns
A Relationship Base Object models many-to-many associations between two entities by storing foreign key references to both related base objects, enabling complex relationship tracking.
Question 6: What does 'tokenization' accomplish during the MDM Hub match process?
- Encrypts sensitive PII fields before storage
- Generates phonetic or fuzzy search keys from field values to enable efficient candidate pair selection (Correct answer)
- Assigns unique identifiers to new records entering staging
- Splits multi-value fields into separate match columns
Correct answer: Generates phonetic or fuzzy search keys from field values to enable efficient candidate pair selection
Tokenization converts field values into standardized search tokens (e.g., NYSIIS, Soundex) that allow MDM Hub to efficiently find candidate record pairs for detailed comparison.
Question 7: In Informatica MDM Hub, what is the 'Hub Console' primarily used for?
- Executing SIF API calls to read and write master data
- Providing a web-based administration interface for configuring all hub components (Correct answer)
- Running batch load and match jobs via command line
- Monitoring real-time data streaming into the hub
Correct answer: Providing a web-based administration interface for configuring all hub components
The Hub Console is the web-based administrative GUI used to configure all MDM Hub components including schema, match rules, trust settings, and security.
