What does "data governance" involve?

Data governance primarily focuses on the policies and processes that ensure high data quality, proper accessibility, and the management of data usage throughout an organization. This involves establishing standards and guidelines that dictate how data is to be handled, who can access it, and under what conditions. Effective data governance helps organizations maintain regulatory compliance, secure sensitive data, and enhance the overall trustworthiness of their data, which is critical for informed decision-making and strategic planning.

The other options pertain to different aspects of data management or application lifecycle and do not encapsulate the core concepts of data governance. For instance, managing application deployment processes, creating visualization tools, or deploying analytics applications are all valuable tasks but do not inherently involve the governance of data itself. Therefore, the focus on quality, accessibility, and usage policies in choice B accurately captures the essence of data governance.
