Abstract
This paper addresses the problem of how to specify changes in multidimensional databases. These changes may be motivated by evolutions of user requirements as well as changes of operational sources. The multiversion-based multidimensional model we provide supports both data and structure changes. The approach consists in storing star versions according to relevant structure changes whereas data changes are recorded through dimension instances and fact instances in a star version. The model is able to integrate mapping functions to populate multiversion-based multidimensional databases. © Springer-Verlag Berlin Heidelberg 2006.
