A multidimensional database can be seen as a collection of multidimensional cubes, from which information is usually extracted by aggregation; aggregated data can be calculated ei...
—The rapid advances in a wide range of wireless access technologies along with an industry-wide IP-convergence have set up the stage for context-aware computing. The “locationâ...
Computing aggregates over selected categories of multidimensional discrete data (MDD) cubes is the core operation of many on-line analytical processing (OLAP) systems. In order to...
