What is the best definition of data accessibility?

Data accessibility refers to how easily users can obtain and utilize data when needed. This concept emphasizes the importance of having data readily available and obtainable for analysis, reporting, and decision-making processes. In many contexts, especially within healthcare and information governance, data accessibility ensures that all stakeholders, including clinicians and administrators, can access the information they require in a timely manner to support patient care and operational workflow.

While data being correct, including all required elements, or being reliable are critical attributes of data quality and integrity, they do not specifically address the notion of how easily that data can be acquired or accessed by users. Therefore, the focus on ease of obtaining data is what makes it the best definition of data accessibility.
