Definition
A Data Steward is a person responsible for the ongoing quality, consistency, completeness and compliance of data according to rules established by the Data Owner.
Human Explanation
The Data Steward helps keep data correct, current and consistent with agreed standards.
Why it Matters
Even well-defined Data Governance rules create little value without daily oversight of Data Quality.
Conceptual Boundary
A Data Steward does not establish the organisation's data policy. The role applies that policy in practice.
Practical Perspective
Responsibilities may include monitoring Data Quality, identifying errors, coordinating corrections and working with Data Owners and business users.
