3.6 Information System Structure

Information systems, such as structured databases, can be defined primarily as either 'open' or 'closed'.

Open Information Systems

Closed Information Systems

  • This type of system can interact with other information systems (e.g. another database) to exchange data, even from different platforms (types of computers).​

  • Because it is open, it is more at risk of data loss and hacking.

  • 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.
