Outline the five functions of an information system.
The five functions performed by an MIS system are
- Collecting data,
- Storing data,
- Updating data,
- Processing data into information, and
- Presenting information.
Data may be collected from internal sources and external sources. An MIS must be able to store data until they are needed and to update them regularly to ensure that the information presented to managers and employees is accurate, complete, and timely.
Data processing is the MIS function that transforms stored data into a form useful for a specific purpose. Finally, the processed data (which now can be called information) must be presented for use. Verbal information generally is presented in the form of a report.
Numerical information most often is displayed in graphs, charts, or tables.
In addition to the five basic functions performed by an MIS, managers and employees can use a decision-support system (DSS), an executive information system (EIS), expert system, and business application software to make decisions and to report data and information.
