  1. 1. Scalable Queries over Log Database Collections

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Minpeng Zhu; Uppsala universitet.; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : In industrial settings, machines such as trucks, hydraulic pumps, etc. are widely distributed at different geographic locations where sensors on machines produce large volumes of data. The data produced is stored locally in autonomous databases called log databases. LÄS MER

  2. 2. Querying Data Providing Web Services

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Manivasakan Sabesan; Uppsala universitet.; Uppsala universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; views of web service operations; web service queries; adaptive parallelization; query optimization; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : Web services are often used for search computing where data is retrieved from servers providing information of different kinds. Such data providing web services return a set of objects for a given set of parameters without any side effects. LÄS MER

  3. 3. Integrating Visual Data Flow Programming with Data Stream Management

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lars Melander; Uppsala universitet.; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data stream management; data stream visualization; visual data flow programming; LabVIEW; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : Data stream management and data flow programming have many things in common. In both cases one wants to transfer possibly infinite sequences of data items from one place to another, while performing transformations to the data. LÄS MER

  4. 4. Main-Memory Query Processing Utilizing External Indexes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Thanh Truong; Uppsala universitet.; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Database indexing; query processing; index structures; main-memory; index validation; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : Many applications require storage and indexing of new kinds of data in main-memory, e.g. color histograms, textures, shape features, gene sequences, sensor readings, or financial time series. LÄS MER

  5. 5. Scalable Preservation, Reconstruction, and Querying of Databases in terms of Semantic Web Representations

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Silvia Stefanova; Uppsala universitet.; Uppsala universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RDF; RDFS; RDF view; SPARQL; SPARQL query processing; rewrite optimization; Topic Maps; querying of RDF views; archive relational databases; reconstruct archived databases; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : This Thesis addresses how Semantic Web representations, in particular RDF, can enable flexible and scalable preservation, recreation, and querying of databases.An approach has been developed for selective scalable long-term archival of relational databases (RDBs) as RDF, implemented in the SAQ (Semantic Archive and Query) system.
