Faced to the large amounts of data and the remarkable diversification of their sources, a scientific and economic interest to explore the reservoirs of knowledge is established. Data warehouses are used in making strategic decisions. A data warehouse is a collection of integrated, historised data originating from heterogeneous sources which gives rise to business bases (data store). Several approaches proposed semi-automatic building data warehouses. In this paper, the authors present an overview of those works dedicated to the design of data warehouses and a comparison of these different approaches.
