The overall management of the availability, usability, integrity, and security of data employed in an enterprise.
Data Governance is the overarching framework of internal policies, rules, and standards that ensure an organization's data is accurate, secure, and used responsibly.
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.
