Data warehouse testing

none2Testing is an essential part of the design life-cycle of any software product. Nevertheless, while most phases of data warehouse design have received considerable attention in the literature, not much has been written about data warehouse testing. In this paper we introduce a number of data mart-specific testing activities, we classify them in terms of what is tested and how it is tested, and we show how they can be framed within a reference design method to devise a comprehensive and scalable approach. Finally, we discuss some practical evidences emerging from a real case study.mixedM. Golfarelli; S. RizziM. Golfarelli; S. Rizz
