Towards Data Warehouse Quality Metrics

Organizations are adopting datawarehouses to manage information efficiently as “the” main organizational asset. It is essential that we can assure the information quality of the data warehouse, as it became the main tool for strategic decisions. Information quality depends on presentation quality and the data warehouse quality. This last includes the multidimensional model quality. In the last years different authors have proposed some useful guidelines to design multidimensional models, however more objective indicators are needed to help designers and managers to develop quality datawarehouses. In this paper a first proposal of metrics for multidimensional model quality is shown together with their formal validation.
