Data stewardship is the ongoing responsibility of managing data so it remains accurate, accessible, secure, and appropriately used. A data steward helps define and enforce standards for how data is created, documented, classified, shared, and maintained. Unlike a purely technical role, stewardship connects data management practices with the business meaning and rules that govern the information.
For example, a customer data steward may establish standards for names, addresses, and customer identifiers across departments, resolve conflicting records, and ensure sensitive fields are handled according to organizational policies. This helps maintain trusted data as it moves between systems and teams. Data stewardship is closely related to data governance, data quality, metadata management, and data ownership.
