From Information System to Information and Knowledge System

In this paper we notice that all definitions of information system never make a clear distinction between the notion of information and the notion of knowledge. We propose to clarify differences between data, information and knowledge by suggesting a model of an Enterprise’s Information and Knowledge System (EIKS) supported by a Digital Information System. Then, based on our knowledge management research, we propose to transpose the Enterprise’s Knowledge Management System implemented from our Model for General Knowledge Management within the Enterprise (MGKME) to the Enterprise’s Information and Knowledge System. This leads us to describe the EIKS’s components, highlighting two categories of components: underlying components and operating components. Moreover, we consider the perspectives offered by EIKS’s evolution.
