The database contains the data provided by the AIS. In addition both data and information are entered from the environment. Software that produces periodic and special reports, as well as mathematical models that simulate various aspects of the firm's operations uses the database contents. Persons who are responsible for solving the firm's problems use the software outputs. Some of the problem solvers can exist within the firm's environment. The environment becomes involved when the firm brands together with such other organisations as suppliers to form an inter-organisational information system (IOS). In that case, the MIS supplies information to the other members of the IOS.
