BioSense, the application developed by the CDC to report on disease trends, would be best classified as a(n):

BioSense, developed by the CDC for monitoring disease trends, is best classified as a management information system. This is because it gathers, processes, and provides essential data about public health trends, which aligns with the primary purpose of management information systems. These systems are designed to help organizations manage operations and make informed decisions based on analyzed data. BioSense not only collects raw data on disease occurrences but also analyzes and presents this information in a way that aids healthcare management and policymaking.

In contrast, a transaction processing system primarily focuses on managing and processing day-to-day transactions rather than providing overviews of trends and aggregated data. A decision-support system is intended for analytical and decision-making processes but is more focused on producing insights rather than operational management. An executive-support system targets senior management with highly summarized data for strategic decisions, which is not the primary function of BioSense. The application’s emphasis on health monitoring and reporting over time directly supports operational and tactical management, confirming its classification as a management information system.
