Object-oriented data model for data warehouse

Abstract

Data Warehouse is frequently organized as collection of multidimensional data cubes, which represent data in the form of data values, called measures, associated with multiple dimensions and their multiple levels. However, some application areas need more expressive model for description its data. This paper presents the extension of classical multidimensional model to make Data Warehouse more flexible, natural and simple. The concepts and the basic ideas was taken from the classical multidimensional model to propose an approach based on Object-Oriented Paradigm. In this research Object-Oriented Data Model is used for description of Data Warehouse data and basic operations over this model are provided. © Springer-Verlag Berlin Heidelberg 2002.
