Datacubes: A Technology Survey
Peter Baumann, Dimitar Mišev, Vlad Merticariu, Bang Pham Huu, Brennan Bell · 2018
Datacubes are emerging as a paradigm which allows offering massive spatio-temporal data more in a more homogenized and better to analyze fashion, in particular when it comes to mixed spatial and temporal evaluation. While this is agreed by many, there is no broad consensus yet on access APIs and paradigms, such as query languages versus procedural interfaces. Further, questions of efficient storage organization and processing of the underlying multi-dimensional arrays arise. In our contribution we provide a technology overview on datacube approaches, involving Array Databases, systems with procedural (typically python) interfaces, array libraries, and more.
