Compressed Aggregations for mobile OLAP Dissemination
As wireless network infrastructure becomes more reliable, an increasing number of traditional desktop applications, beyond common web browsing, migrate to portable devices. Since ubiquitous access has become a critical success factor for most enterprises, business mobile information systems become a necessity. This paper deals with the case of mobile access to multidimensional data. We introduce the m-Dwarf, a compressed data cube physical structure, which has no loss of semantic information and is explicitly designed for mobile applications. m-Dwarfs are integrated in a mobile OLAP dissemination system. Experimental evaluation reveals a substantial reduction of access time, energy consumption and bandwidth utilization.
