....combinations of attributes. Therefore, queries are more complex and may take long time to complete. To face up to this problem, a great deal of effort has been invested in developing techniques for optimizing queries involving views and aggregate functions (Harinarayan al 1996, Gray al 1996, Ho al 1997, Levy al 1996, Ross al 1994) Unfortunately, a unifying framework for multidimensional databases is still missing. Hence, different multidimensional models, operators, techniques, etc. cannot be compared to each other or evaluated. Furthermore, there is a certain lack of common vocabulary and ....

....understanding of multidimensional databases and related operations, by using a vocabulary which is appropriate for the problem domain. It also allows the use of cube operations by making it easier for the user to interpret them. This work integrates formalisms that have been developed for Data Warehouse (Agrawal al 1997, Gray al 1996, Ho al 1997) and in knowledge representation (Borgida 1992, Borgida 1995, Baader Hanschke 1991, Brachman Schmolze 1985, SchmidtSchauss Smolka 1991) It is a first step towards the development of a framework which 1) is equipped with well defined semantics and 2) allows the ....
