Which role is primarily responsible for ensuring compliance with data governance policies?

The role primarily responsible for ensuring compliance with data governance policies is the Data Steward. This position is crucial in managing data integrity, quality, and adherence to established governance frameworks within an organization. Data Stewards are tasked with the oversight of data assets and act as liaisons between business units and technical teams, ensuring that data handling practices align with the organization's governance standards and regulatory requirements.

This responsibility includes monitoring how data is used, facilitating data quality initiatives, implementing governance policies, and serving as the point of contact for any compliance issues related to data management. They play an essential role in documenting data definitions, understanding the data lifecycle, and promoting best practices throughout the organization.

The other roles mentioned do have important functions within data management. However, they focus on different aspects: Data Architects design and implement data systems; Data Scientists analyze and interpret complex data; and Database Administrators manage the technical aspects of databases. While all these roles contribute to data management, none specifically focus on the enforcement and compliance aspect of governance as directly as the Data Steward does.
