Towards an energy aware DBMS: energy consumptions of sorting and join algorithms Database management systems Höpfner, Hagen , 1977- (VerfasserIn) Bunse, Christian , 1967- (VerfasserIn) Text Text 2009 2009 eng electronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource (Seiten 69-73) Database management systems comprise various algorithms for efficiently retrieving and managing data. Typically, algorithm efficiency or performance is correlated with execution speed. However, the uptime of battery powered mobile- and embedded systems strongly depends on the energy consumption of the involved components. This paper reports our results concerning the energy consumption of different implementations of sorting and join algorithms. We demonstrate that high performance algorithms often require more energy than slower ones. Furthermore, we show that dynamically exchanging algorithms at runtime results in a better throughput.<eng> Hagen Höpfner; Christian Bunse 004 http://purl.uni-rostock.de/rosdok/id00002192 21.
