Enabling OLAP analyses on the web of data
Franck Ravat, Jiefu Song · 2016
This paper describes a business-oriented analysis environment facilitating analyses of coherent data from Data Warehouses (DWs) and Linked Open Data (LOD) datasets. Specifically, we present a multidimensional modeling solution, named Unified Cube, which provides a single, comprehensive representation of data from multiple sources. Unified Cubes include both concepts close to business terms and user-friendly graphical notations. An implementation framework is proposed to enable unified analyses of warehoused data and LOD. The feasibility of the proposed concepts is illustrated with examples based on real-world datasets.
