Explain the term "data governance."

The term "data governance" refers to a comprehensive framework designed to manage data within an organization. This framework encompasses various critical aspects of data management, including availability, usability, integrity, and security.

Effective data governance ensures that data is not only accessible to those who require it for decision-making but that it is also reliable and maintained with high standards of quality. By implementing data governance practices, organizations can establish policies and procedures that dictate how data is handled, shared, and protected. This ultimately leads to better decision-making, compliance with regulations, and safeguarding of sensitive information.

In contrast, the other options do not encompass the full breadth and importance of data governance. Maintaining rules for data disposal, while necessary, only addresses a specific part of data lifecycle management without covering broader governance issues. Similarly, improving storage efficiency and enhancing data visualization are important objectives but do not directly relate to overseeing and managing the overall quality and management of data within an organization.
