Quizplus · Accepted Answer

The critical difference between a DSS (Decision Support System) and an MIS (Management Information System) is not about their web-based or computer-restricted nature. DSS is a computer-based information system that combines data, analytical tools, and models to support semi-structured and unstructured decision-making tasks. Meanwhile, an MIS is a computer-based system that provides managers with tools to organize, evaluate, and manage information to support decision-making processes within an organization. Both DSS and MIS may be web-based or computer-restricted depending on the organization's security policies and other requirements.
