Which statement best describes a database?

A database is fundamentally a collection of related data that is organized for easy access, management, and updating. This definition encompasses the idea that data can be stored centrally, as in a single physical location, or distributed across multiple locations, which is common in modern database systems.

This characteristic allows databases to efficiently manage vast amounts of information, making it possible for users to query and retrieve data as needed. The structure of a database supports various relationships between data elements, enabling users to analyze and manipulate data systematically.

In contrast, the other options describe specific applications or functions related to health data but do not capture the broader definition of what a database is. One option focuses on public health outcomes, another suggests a software tool for patient tracking, and another discusses statistical data compilation, each of which is more specialized than the general concept of a database itself.
