  • On synchronous properties of periodically generated data sequences

    Publication Year: 1999, Page(s):294 - 301
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (280 KB)

    We address the problem of choosing synchronous data combinations from periodically generated data sequences (PGDAs). In real time systems, PGDAs play a major role. When integrating PGDAs generated from various information sources, we face the problem of choosing which data combinations to use, since different PGDAs, in general, have different data generation intervals. A data combination is define... View full abstract»

    Many business processes which are abstracted to workflows have time constraints such that their processing should be completed within their deadlines. New time management technologies are therefore required for high workflow throughput which can maximize the number of workflow instances satisfying their deadlines. In this paper we propose an efficient deadline assignment method and validate its us... View full abstract»

    On-line analytical processing (OLAP) queries can take hours or even days to execute on very large data warehouses. Therefore, there is a need to employ techniques that can facilitate efficient execution of these queries. The data partitioning concept that has been studied in the context of relational databases aims to reduce query execution time and facilitate the parallel execution of queries. In...

  • Parallel spatial join algorithms using grid files

    Publication Year: 1999, Page(s):226 - 234
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (404 KB)

    The most costly spatial operation in spatial databases is a spatial join which combines objects from two data sets based on spatial predicates such as intersects or contains. Even if the execution time of sequential spatial join processing has improved over the last few years, the response time is far from meeting the requirements of interactive users. In this paper, we have designed two kinds of ... View full abstract»
