According to the hierarchy in the organization, the information system can be classified into four types that are Executive Information Systems (EIS) which is used to get tactical knowledge required by executives. Another is Decision Support Systems (DSS) which provides the explicit knowledge required by senior managers that are working in the organisation. In addition to that, Management Information Systems (MIS) and Office Support Systems (OSS) help to provide information to middle-level managers.
