Add to ORKGWe present the logical “OLAP-XML Federation System” that enables the external data available in XML format to be used as virtual dimensions. Unlike the complex andtime-consuming physical integration of OLAP and external data in current OLAP systems, our system makes OLAP queries referencing fast-changing external data possible. This demo shows the uses of XML data for selection and grouping and explains the query optimization and evaluation processes with a concrete example
