Data governance holds significant importance in organizations dealing with big data as it ensures the quality, security, and usability of data throughout its lifecycle. Effective data governance establishes policies, procedures, and standards that define data management practices, from data collection to usage and sharing. By enforcing compliance and accountability, organizations can mitigate risks associated with data breaches and regulatory violations. Strong governance frameworks also foster trust in data-driven decision-making, enabling organizations to harness the full value of their data assets while promoting ethical data usage.
