CompTIA Data+ (DA0-002)Data Governance, Quality and ControlsMedium

A senior executive separately holds ultimate accountability for the overall business value and risk of that data asset. Which role does the first individual perform?
- AData Custodian
- BData Owner
- CData Architect
- DData Steward
Show answer & explanationAnswer & explanation
Correct answer: D. Data Steward
The Data Steward is responsible for day-to-day management of data quality, definitions, and issue resolution, while the Data Owner holds ultimate accountability for the asset. The Data Custodian handles technical storage and security, and the Data Architect designs data structures.
Why the other options are wrong
- A. The Data Custodian is responsible for technical storage/security, not quality rules.
- B. The Data Owner holds ultimate accountability, described here as the executive.
- C. The Data Architect designs data models and structures, not quality management.
Data Steward
A governance role responsible for the day-to-day management, quality, and definition of data assets on behalf of the data owner.
- Manages data quality rules and standards
- Resolves data issues raised by business users
- Works between the data owner and technical teams
Memory trick: Owner decides, Steward manages, Custodian stores, User consumes.
