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.
