Types of information systems
Open Systems
Closed Systems
Open information system
This type of system can interact with other information systems (e.g. another database) to exchange data, even from different platforms (types of computers).
Disadvantages: it is more at risk of data loss and/or hacking as it communicates with other systems.
Closed Information Systems
This type of system is private and cannot exchange data with other systems.
Access is limited but it is much more secure than an open system.
