Zusammenfassung. Die Nutzung komplexer Algorithmen zur Analyse oft hochdimensionaler Datensätze gerät im Kontext von " Big Data " immer mehr in das Zentrum der Aufmerksamkeit. Um diese komple-xen Datenanalysen effizient zu ermöglichen liegt es nahe, sie in die am weitesten verbreiteten Datenspeicher zu integrieren – in relationale Da-tenbanksysteme. Dies(More)
At the present day the world wide web is full of music. Highly effective algorithms for music compression and high data storage has made it easy to access all kind of music easily. However, it is not possible to look for a similar piece of music or a sound as easily as to google for a similar kind of text. Music is filtered by its title or artist. Although(More)
Data measured in wireless sensor networks are inherently imprecise, due to a number of reasons, and aggregate queries are often used to analyze the collected data in order to alleviate the impact of such imprecision. In this paper we will deal with the imprecision in the measured values explicitly by employing a probabilistic approach and we focus on one(More)
