Automatic Validation of Requirements to Support Multidimensional Design
It is widely accepted that the conceptual schema of a data warehouse must be structured according to the multidimensional model. Moreover, it has been suggested that the ideal scenario for deriving the multidimensional conceptual schema of the data warehouse would consist of a hybrid approach (i.e., a combination of data-driven and requirement-driven paradigms). Thus, the resulting multidimensional schema would satisfy the end-user requirements and would be conciliated with the data sources. Most current methods follow both a data-driven or requirement-driven paradigm and only a few uses a hybrid approach.
