Management Information System
     
         (MIS) A computer system, usually based on a
        {mainframe} or {minicomputer}, designed to provide management
        personnel with up-to-date information on an organisation's
        performance, e.g. inventory and sales.  These systems output
        information in a form that is useable by managers at all
        levels of the organisation: strategic, tactical, and
        operational.  A good example of an MIS report is an annual
        report for a stockholder (a scheduled report).
