Concept of an Information System

A company creates value by processing information, particularly in the case of service companies. So, information has a much greater value because it contributes to achieving the company's objectives.

An information system (written IS) represents all the elements involved in the management, processing, transport and distribution of information within the organisation.

In practical terms the scope of the term Information System can differ greatly from one organisation to another and depending on the example may cover all or some of the following elements:

• Company databases,
• Integrated management software (ERP),
• Client relationship management tool (Customer RelationShip Management),
• Supply chain management tool (SCM - Supply Chain Management),
• Application jobs,
• Network infrastructure,
• Data servers and storage systems,
• Application servers,
• Security devices.
