They work closely with IT security teams to attain data access policies, monitor user activity, and mitigate security risks.
  • Metadata Management: Metadata, which provides context and information about data assets, is managed and curated by Data Stewards. They define metadata standards, tags, and classifications to enhance data discoverability, lineage, and understanding across the organization.
  • Data Lifecycle Management: Throughout the lifecycle of data, from creation to archival or deletion, Data Stewards oversee its management and governance. They establish policies and procedures for data retention, archival, and disposal, ensuring compliance with regulatory requirements and business needs.

Data Owner Overview

Data Owners are individuals or groups responsible for overseeing specific organizational datasets. They hold the ultimate authority and accountability for the data they manage, ensuring its integrity, confidentiality, and appropriate use throughout its lifecycle.

Data Owner Responsibilities

  • Data Ownership and Accountability: One of the primary roles of a Data Owner is to establish clear ownership of the data assets within their area of responsibility. This involves defining ownership rights, responsibilities, and authorities over specific datasets to ensure that individuals or teams are held accountable for the data's accuracy, reliability, and security. 
  • Data Classification and Prioritization: Data Owners are responsible for classifying and prioritizing data assets based on their importance, sensitivity, and criticality to the organization. This involves categorizing data into different classes or levels based on factors such as confidentiality, integrity, availability, and regulatory requirements.
  • Data Usage and Access Control: The task of the Data Owner is to oversee data usage and control to ensure that data is used appropriately and securely. This includes defining access controls, permissions, and authentication mechanisms to govern who can access, modify, or delete data assets. They also decide which datasets are going to be assigned to different Data Stewards.
  • Data Privacy and Compliance: They are responsible for implementing measures to protect sensitive information from unauthorized access, disclosure, or misuse. This includes implementing data anonymization and encryption techniques and conducting privacy impact assessments. While ensuring that data handling practices comply with applicable regulations such as GDPR, CCPA, and HIPAA.
  • Data Stewardship Collaboration: Collaboration with Data Stewards is essential for effective data governance and management. Data Owners work closely with Data Stewards to support data governance initiatives, enforce data policies and standards, and resolve data-related issues and challenges.

Data Steward vs Data Owner: Key Differences

While both Data Stewards and Data Owners are integral to data governance, they differ significantly in their responsibilities, authority, and focus. Here are a few key differences between them:

Aspect Data Steward Data Owner
Responsibility Ensures data complies with regulations, policies, and standards. Implements data governance practices. Determines data governance policies, including access controls, data retention, and privacy policies.
Role Focus Focuses on day-to-day data management tasks and operational issues. Focuses on strategic decision-making regarding data and its usage.
Collaboration Collaborates operationally with data analysts, scientists, IT, and business teams to ensure data quality and governance. Collaborates strategically with senior management, legal, and external partners to align data strategies with business goals and ensure compliance.
Accountability Ensures adherence to data policies and procedures and resolves data-related issues. Holds ultimate accountability for data quality, security, and regulatory compliance.
Decision-Making May participate in data-related decisions but typically not the final authority. Makes decisions regarding data strategy, usage, and investments, often in consultation with stakeholders.
Authority Implements data-related decisions based on policies and guidelines set by the Data Owner. Holds authority over data-related decisions and policies.
Expertise Requires a strong understanding of data management practices, governance principles, and relevant technologies. Deep knowledge of business processes, compliance regulations, and data management practices is required.

Data Owner vs Data Steward: Relationship

The relationship between data Stewards and Owners is similar to a partnership where each plays a distinct yet complementary role in managing and maintaining data assets. The Data Owner is responsible for defining the strategic direction and priorities for the data. And the data Steward focuses on implementing policies, procedures, and practices to ensure the data's integrity, quality, as well as security.

Data Owners oversee data acquisition, storage, and usage within an organization, making decisions about data classification, access permissions, and compliance with regulations. They establish data governance policies and guidelines, define data ownership, and ensure alignment with organizational objectives and regulatory requirements.

On the other hand, Data Stewards are tasked with executing the data governance policies set by Data Owners. They work with data, performing data profiling, implementing cleansing practices, and metadata management. Data Stewards collaborate with Data Owners to understand requirements and formulate data management plans. Once the plans are established by Data Owners, Stewards execute them, fostering a continuous feedback loop between operational execution and strategic oversight.

While Data Owners provide the vision and direction for data management, Data Stewards are responsible for implementing as well as operationalizing those directives. They work together to ensure data assets are effectively managed, protected, and utilized to support business goals along with the decision-making processes. This collaborative relationship is essential for maintaining data quality, integrity, and compliance while maximizing the value of data assets for the organization.

Real World Example to Understand Data Owner vs Data Steward

Here are some real-world examples to understand the roles in a better way:


In a retail chain scenario, let's explore the roles through the lenses of a Data Steward and a Data Owner:

  • Data Steward (Digital Marketing Team): A digital marketing team member is responsible for validating and cleaning customer data collected from sweepstake entries. They ensure data quality by systematically formatting, cleaning, and enriching the dataset in line with data governance policies.
  • Data Owner (Head of Sales): The Head of Sales oversees sales targets and is deeply involved in the success of marketing campaigns. As the Data Owner, they have the authority and resources to enhance data quality and security. For instance, they may invest in technology to automate data capture or enforce authentication measures to protect data access.

In this scenario, the Data Steward focuses on maintaining data quality, while the Data Owner oversees strategic decisions related to data management. This illustrates data stewardship's distinct yet complementary roles in organizational data governance.


In a contract manufacturing company, the Production Manager assumes the role of Data Owner, overseeing all production-related data. Under this arrangement, various individuals are appointed as Data Stewards, each responsible for specific datasets:
