Which statement best describes a data requirement?

• A. Specifies user interface style
• B. Specifies data formats and storage needs
• C. Specifies system response time
• D. Specifies organizational policies

Answer: (B)

Data requirements describe what data a system must handle and how that data is organized, stored, and exchanged. They define things like data formats, data structures, data elements, and storage needs so that data can be captured correctly, stored reliably, and shared with other systems when needed. Because data formats determine how the information is encoded (for example, whether patient demographics or lab results use a particular standard or file format) and storage needs determine capacity, retention, backup, and access requirements, this option best reflects the idea of data requirements. Other aspects described in the other choices relate to presentation, performance, or governance rather than the data itself. Specifying user interface style concerns how information is displayed to users, not how data is formatted or stored. System response time worries performance. Organizational policies relate to rules and governance rather than the data’s structure or storage.
