We propose a bulk loading algorithm that can avoid random disk accesses by reducing multiple accesses to the same location into a single access and reordering the acces

Ashley W. Seifert,Joshua D. Currie. While much recent research has been focused on the design of multidimensional conceptual models, only few works were done to develop models and tools to analyze them. Despite specificities (OLAP, historicization, ...) of these requirements, most of the previous works used an E/R or UML schemas whi

Founding on very efficient data compression solutions for two-dimensional data domains, the proposed technique relies on the amenity of generating “semantics-aware” compressed representation of two-dimensional OLAP views extracted from multidimensional data cubes vi
