The join is the most important, but also the most time consuming operation in relational database systems. We implemented the parallel Hybrid Hash Join algorithm on a PC-cluster a...
Modern operating systems frequently support applications with a variety of timing constraints including hard real-time, soft real-time, and best-effort. To guarantee performance, ...
Abstract. Data in many industrial application systems are often neither completely structured nor unstructured. Consequently semi-structured data models such as XML have become pop...
Abstract— In parallel query-processing environments, accurate, time-oriented progress indicators could provide much utility given that inter- and intra-query execution times can ...
In this work we tackle the following problem: given a timed automaton, and a target set F of configurations, restrict its transition relation in a systematic way so that from ever...
