Abstract:
Face to their merger and/or collaboration with partners, today’s enterprises often need to integrate several databases. As a result, their decision making process ends up analyzing data coming from various databases. While database integration has been thoroughly examined, it is only recently that the integration of multidimensional models has drawn attention. A multidimensional model is a data model that facilitates the analysis operations during the decision making process. It organizes data into facts that can be analyzed according to dimensions represented through hierarchies. This paper presents an integration process for the hierarchy concept. In particular, it proposes a set of basic integration operations and constraints that produce a multidimensional model that is loadable from different data sources. It illustrates the integration process through examples.
