Management Information System (MIS) is a computer-based system that processes data into information to support management, operations, and decision-making in an organization. It provides managers with tools to organize, evaluate, and efficiently manage departments. A MIS integrates hardware, software, data, people, and procedures to facilitate information flow between all business activities and manage an organization's resources. It helps management with planning, control, performance evaluation, and decision-making through reports that summarize and analyze data in an easy-to-understand format.
