Strategic decision support systems design: integration approach between expert knowledge and historical data

The design of strategic decision support systems passes by the organization of sources of knowledge: problems of multiplicity of the sources, therefore of heterogeneity of the supports and techniques, aggregation of knowledge and cooperation. We focus on the aggregated methods and more particularly the KDD (knowledge discovery from databases) method and datawarehousing. We show that KDD and datawarehousing are complementary solutions for organizations in the search of knowledge.
