Data-Information-Knowledge-Wisdom (DIKW) Pyramid, Framework, Continuum
Living reference work entry
The Data-Information-Knowledge-Wisdom (DIKW) hierarchy, or pyramid, relates data, information, knowledge, and wisdom as four layers in a pyramid. Data is the foundation of the pyramid, information is the next layer, then knowledge, and, finally, wisdom is the apex. DIKW is a model or construct that has been used widely within Information Science and Knowledge Management. Some theoreticians in library and information science have used DIKW to offer an account of logico-conceptual constructions of interest to them, particularly concepts relating to knowledge and epistemology. In a separate realm, managers of information in business process settings have seen the DIKW model as having a role in the task meeting real world practical challenges involving information (Fig. 1).
