Hardware vendors constantly decrease the feature sizes of integrated circuits to obtain higher performance and energy efficiency. As a side-effect, integrated circuits - like CPUs and main memory - become more and more vulnerable to external influences and thus unreliable, which results in increasing numbers of (multi-) ...

Query-specific code generation has become a well-established approach to speed up query execution. However, this approach has two major drawbacks: (1) code generators are in general hard to write and maintain, (2) code generators lack the ability to deal with custom operators. To overcome these limitations, we suggest ...

In Hauptspeicher-zentrischen Architekturansätzen für Datenbanksysteme müssen für die Anfrageverarbeitung sowohl die Basisrelationen als auch die Zwischenergebnisse im Hauptspeicher gehalten werden. Des Weiteren ist der Aufwand, um Zwischenergebnisse zu generieren, äquivalent zum Aufwand, um Änderungen an den Basisrelationen ...
