Evolving OLAP and BI towards Complex, High-Performance Big-OLAP-Data-Cube-Processing Analytics Frameworks: How to Speed-Up Large-Scale, High-Dimensional Queries over Clouds
Alfredo Cuzzocrea · Procedia Computer Science · 2024
Starting from traditional OLAP and BI systems, this paper explores a new line of research represented by the so-called multidimensional big data analytics . This is an emerging area that is conquering the scene time by time, particularly due to its nice amenities to be found both in the theoretical as well as the industrial settings. In this respect, the paper proposes a methodology and a reference architecture for representing big OLAP data cubes over Clouds via columns , which mostly capture the intrinsic dimensions of the target cube. A preliminary evaluation of the methodology is also provided. Finally, an overview on future research directions in the investigated scientific field completes the contributions of this paper.
