Designing a parallel data warehouse consists of choosing the hardware architecture, fragmenting the data warehouse schema, allocating the generated fragments, replicating fragments to ensure high system performance and defining the treatment strategy and load balancing.The major drawback of this design cycle is its ignorance of the interdependence between subproblems related to the design of PDW and the use of heterogeneous metrics to achieve thesame goal. Our first proposal defines an analytical cost model for parallel processing of OLAP queries in a cluster environment. Our second takes into account the interdependence existing between fragmentation and allocation. In this context, we proposed a new approach to designa PDW on a cluster ma...
