Sažetak
Since XML has become a standard for data exchange over the Internet, especially in B2B and B2C communication, there is an increasing need of integrating XML data into data warehousing systems. In this paper we propose a methodology for data warehouse design, when data sources are XML Schemas and conforming XML documents. Particular relevance is given to the conceptual and logical multidimensional design. A prototype tool has been developed to verify and support our methodology. Because of the semistructured nature of XML data, not all the information needed for design can be safely derived from XML Schema. In these situations, XQuery statements are generated by the tool to examine XML documents. The functionality of the tool is explained on a real-life XML Schema that describes purchase orders.
