A Cloud-Based Multidimensional Big Data Framework for Healthcare Analytics: Bridging OLAP and Cognitive Insights in Chronic Pain Management

By considering the real-life research project Pain-RELife, which focuses attention on big data management and analytics tools over patients suffering from chronic pain, located in the Region Lombardy of North Italy, this paper provides a relevant journey from theory to practice about so-called Multidimensional Big Data Analytics tools over (real-life) big healthcare datasets, as dictated by the effective project goals. This constitutes an effective contribution to the state-of-the-art research. Our conceptual and theoretical results are corroborated by a comprehensive campaign of real-life experimental results focused on advanced tools such as Multidimensional Clustering and Multidimensional Regression.
