Abstract
The unclear distinction between data, information, and knowledge has impaired their combination and utilization
for the development of integrated systems. There is need for a unified definitional model of data, information, and
knowledge based on their roles in computational and cognitive information processing. An attempt to clarify these
basic notions is made, and a conceptual framework for integration is suggested by focusing on their different roles and
frames of reference within a decision-making process. On this basis, ways of integrating the functionalities of
databases, information systems and knowledge-based systems are discussed by taking a knowledge level perspective to
