Integrating Semantics within Compressed OLAP Views in the Hand-OLAP System (original) (raw)

In this paper, we provide further extensions of Hand-OLAP, a Java-based distributed system for enabling OLAP in mobile environments via intelligent data cube compression approaches. These extensions aim at integrating innovative semantics representation and management models within compressed OLAP views, in order to improve the data cube compression process itself, and to support an improved summarized, OLAP-like knowledge fruition from multidimensional data cubes throughout mobile devices. We complete our analytical contribution by means of an experimental evaluation of the novel semantics-based data cube compression approach on well-known benchmark data cubes, which definitely confirms to us the efficiency and the reliability of our proposed research.
