What is Data Stewardship?
Data Stewardship is an approach that involves managing, organizing, and enhancing the quality of data to ensure that an organization's information assets are properly utilized and safeguarded. This concept is crucial as businesses increasingly rely on data collection and analysis for decision making, marketing strategies, and operational efficiency.
Functionality and Features
Data Stewards, the professionals who execute data stewardship, perform a variety of functions that include:
- Establishing data quality standards and enforcing data governance policies.
- Ensuring data accuracy, consistency, and completeness across multiple platforms.
- Facilitating data integration, cleansing, and transformation processes.
- Complying with data privacy regulations and maintaining data security.
- Communicating and coordinating with various stakeholders to ensure data usability.
Benefits and Use Cases
Data Stewardship provides numerous benefits, including:
- Improved data quality, which enhances analytical capabilities and decision making.
- Increased data security and better adherence to data protection regulations.
- Enhanced data accessibility and understandability, promoting data-driven culture within the organization.
Challenges and Limitations
Despite its benefits, Data Stewardship also faces certain challenges, such as:
- The complexity of managing large volumes of heterogeneous data.
- Dependency on human input, which can be error-prone and resource-intensive.
- Need for constant updating and monitoring to keep up with evolving data landscapes and regulations.
Integration with Data Lakehouse
Data Stewardship plays a significant role in a data lakehouse environment. While a data lakehouse combines the benefits of data warehouses and data lakes, it equally requires robust data management practices, such as data stewardship, to ensure data integrity, security, and quality. Data Stewards coordinate the movement of data from various sources into the lakehouse, perform data cleansing, and ensure compliance and data usability.
Security Aspects
Data Stewards are also tasked with maintaining high levels of data security. They often work closely with IT and cybersecurity teams to implement data encryption, manage user access, uphold data privacy standards, and comply with data-related regulatory requirements.
Performance
Effective Data Stewardship can significantly improve the performance of data handling processes, resulting in better quality insights and faster decision-making ability for the organization.
