Specification of the data warehouse for the decision-making dimension of the Bid Process Information System

Bid process is a key business process which influences the enterprise’s survival and strategic orientations. Therefore, the Bid Process Information System (BPIS) that supports this process must be characterized by integrity, flexibility and interoperability. Nevertheless, the specification of this system, has to deal with “three fit” problems. Four dimensions have been identified to cope with such failures: operational, organizational, decision-making, and cooperative dimensions. In this paper we are particularly interested to organize the decision-making dimension of the BPIS. Thus, we propose an approach for representing data warehouse schema based on an ontology that captures the multidimensional bid-knowledge.
