Abstract: The quality of a data mart (DM) tightly depends on the quality of its multidimensional model. This quality dependence motivated several research efforts to define a set of constraints on the DM model/schema. Currently proposed constraints are either incomplete, or informally presented, which may lead to ambiguous interpretations. The work presented in this paper is a first step towards the definition of a formal framework for the specification and the verification of the quality of DM schemas. In this framework, the quality is expressed in terms of both the syntactic well-formedness of the DM schema as well as its semantic soundness with respect to the DM instances. More precisely, this paper first formalizes in Z the constraints pertinent to the hierarchy concept; the formalization is treated at the meta-model level. Secondly, the paper illustrates how the formalization can be instantiated and the constraints are verified for a particular sample model through the theorem prover Z\eve s. (More)
