From Object-Oriented Conceptual Multidimensional Modeling into XML

Abstract. Data warehouses and OLAP applications are based on the multidimensional (MD) modeling. In this context, we have previously proposed a conceptual modeling approach, based on the Unified Mod-eling Language (UML), to consider main MD properties at the concep-tual level. In this paper, we present how to store a conceptual model accomplished with our approach using the eXtensible Markup Language (XML), a widely used standard for information exchange. To achieve this goal, we provide a DTD that allows us to generate valid XML documents that comprise all MD modeling properties considered by our approach, facilitating the interchange of information between enterprises. After-wards, we also provide XSLT stylesheets that allow us to automatically generate HTML pages from XML documents, thereby supporting differ-ent views of the same MD model easily. Finally, our CASE tool gives support to all theoretical issues presented in the paper
