Difference between MIS and DSS

MIS (Management Information Systems) and DSS (Decision Support Systems) are both types of information systems that are used to support decision making in organizations. Read this tutorial to learn more about MIS and DSS and how they are different from each other.
What is MIS?
MIS, Management Information System, is a computer-based program to assist users to make decisions based on information present in the system. MIS is a type of link that helps in the communication between managers of various departments in a business organization.
MIS plays a vital role in establishing a communication among the corporate people. It is mainly characterized by the input of huge amount of data and the output of summary reports. In MIS, the flow of information takes place in both sides, i.e., up and down.
What is DSS?
DSS, Decision Support System, is a tool that helps in decision-making. It uses communication technologies, data, and documents to identify problems and to finalize decisions.
DSS is a class of digital data systems that provides business and organizational decision-making actions. It is basically a computer-based software that collects, organizes, and analyzes the business data and information to simplify the business decision-making process for administration, services, and planning.
