Data stewards are the operational-level data governance roles who are responsible for implementing and enforcing data policies, standards, and procedures in their respective data domains, such as finance, marketing, or customer data. Data stewards are usually subject matter experts or business users who understand the data needs, quality, and usage of their domains. Data stewards define data definitions, rules, and metadata, identify and resolve data quality issues, document and communicate data changes, and provide data access and support to data consumers.
