This paper presents a concept for the integration of quantitative and qualitative information sources with their accompanying management support functionalities from navigation and retrieval up to analysis and business intelligence. The integration is realized by a common keyword-based metadata base, retrievable and extendible by the end user on a web-based platform. This enables a dynamic acquisition of supplementary information on the usage, usability and benefit of basic and derived information objects, e.g. data warehouses, data marts, OLAP cubes, reports or (textual) documents. Being extended by functions to automatically catch contextual links during system usage, the concept is discussed as a contribution to the implementation of knowledge management. The concept is being developed and successfully tested in the practical environment of a reference project for the implementation of an IT-infrastructure to support decentralized decision-making at a German university.
