The role of data governance in data management involves establishing policies and standards for managing data assets within an organization. It encompasses data quality, security, privacy, and compliance with regulations, ensuring that data is trustworthy, accessible, and appropriately protected. Effective data governance frameworks promote accountability and the responsible use of data across teams, enriching decision-making processes through accurate insights. By defining ownership and stewardship of data, organizations can maximize the value of their data assets while mitigating risks associated with poor data management practices.
