Abstract. Data quality is one of the main issues both when building a Data Warehouse (DW) as when integrating two or more heterogeneous DWs. In the current paper, we perform extensive analysis of a mapping-based DW integration methodology and of its properties. In particular, the method is coherent, meanwhile under certain hypothesis it is able to preserve soundness and consistency. Furthermore, the necessary conditions for homogeneity will be discussed.
