Information system and Computer Information system

The Computer Information System is an ensemble of hardware and software applications. The Information system is an analysis of a problem domain. It is "information oriented". For example, a banking compensation system or a telecommunication protocol are "information systems" in our sense. Their definition does not imply the use of specific software or hardware packages.

Please note that in our definition information systems are not platform specific (hardware, software, language etc..). They might be called also domain systems, abstract systems, general systems etc. The interesting fact is that these systems may be seen also as "knowledge objects", one of the two views related to knowledge management. This view enables the way to "conceptual objects reuse".

The Computer Information System is derived from the Information System by taking into account the platform specifics.
