Management Information Systems (MIS) are like a system of highways, bridges and tunnels that help people travel quickly between two places. Just like roads are used to get people from one place to another, MIS helps people, like companies, get data from one place to another. MIS helps companies track, store, and manage their information - like important documents, customer details, or financial records - quickly and easily, so they don't have to spend lots of time trying to figure it out.
