Numerical Aspects in the Data Model of Conceptual Information Systems
[chapter]
1999
Lecture Notes in Computer Science
Preserved Fulltext
While most data analysis and decision support tools use numerical aspects of the data, Conceptual Information Systems focus on their conceptual structure. ...
In this paper we discuss how the data model of Conceptual Information Systems can be extended by numerical aspects. ...
Introduction The data model of Conceptual Information Systems relies on the insight that concepts are basic units of human thinking, and should hence be activated in data analysis and decision support. ...
