A data steward is:

• A. A system administrator responsible for servers.
• B. A business manager responsible for the quality of data in a particular subject or process area.
• C. A software developer who writes SQL.
• D. An external contractor who audits data.

Answer: (B)

Data stewardship is about who is responsible for the quality and governance of data within a specific business area. A data steward acts as the business-side custodian, defining data standards and policies, monitoring data quality, resolving quality issues, and ensuring data definitions and lineage are clear. They work closely with business users and IT to make sure data supports business decisions. This matches describing a business manager responsible for the quality of data in a particular subject or process area. In contrast, a system administrator focuses on IT infrastructure and server management, a software developer writes SQL and code but doesn't own data quality governance across a domain, and an external contractor may audit data but isn’t the ongoing steward responsible for daily data quality.
