2. Management Information Systems (MIS) – These systems provide managers with the information they need to make decisions and control the organization.
3. Decision Support Systems (DSS) – These systems support specific decision-making tasks and provide users with access to information relevant to their specific needs.
4. Executive Support Systems (ESS) – These systems provide executives with a comprehensive view of the organization and its environment.
5. Expert Systems – These systems incorporate artificial intelligence and knowledge-based techniques to provide advice and recommendations to users.
6. Geographic Information Systems (GIS) – These systems store and manage spatial data and are used in a variety of applications, such as land use planning and natural resource management.

The development and use of information systems can bring many benefits to an organization, such as increased efficiency, better decision making, and improved communication and collaboration.
