On-line analytical processing with conceptual information systems
Gerd Stumme · Kobra (Universitätsbibliothek Kassel) · 1998
A Conceptual Information System consists of a database together with conceptual hierarchies.The management system TOSCANA visualizes arbitrary combinations of conceptual hierarchies by nested line diagrams and allows an on-line interaction with a database to analyze data conceptually.The paper describes the conception of Conceptual Information Systems and discusses the use of their visualization techniques for On-Line Analytical Processing (OLAP).
