Types of Information Systems
The overall information system of an organisation might consist of a number of different types of information systems, including:
- a transaction-processing system
- an office automation system
- a management information system
- an executive information system
- a decision support system
- an expert system.
Most organisations combine both transtion-processing and management information system capabilities, and some also incorporate executive information and decision support system features. While expert systems operate primarily as seperate systems, most organisations combine and intergrate an organisation’s information needs into a single system.
