The policies and named owners that decide how an organization's data may be used and how its quality and security are maintained.
Data Governance is the discipline that keeps an organization's data trustworthy and lawful to use as it moves between teams and systems.
A strong data governance program defines who owns specific data assets, who can access them (often via Role-Based Access Control), and what compliance standards apply.
As enterprises automate data mobilization and adopt AI, data governance is what keeps sensitive information from being accidentally ingested by public models or accessed by unauthorized personnel.
