1. 1. Scalable Data Management for Internet of Things

   Författare :Khalid Mahmood; Tore Risch; Kjell Orsborn; Georgios J Fakas; Erik Zeitler; Vera Goebel; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NoSQL; IoT; Smart Computing; MongoDB; IIoT; Data Streams; Edge Computing; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Sammanfattning : Internet of Things (IoT) often involve considerable numbers of sensors that produce large volumes of data. In this context, efficient management of data could potentially enable automatic decision making based on analytics of sensors on equipment. LÄS MER

3. 2. Scalable Queries over Log Database Collections

   Författare :Minpeng Zhu; Tore Risch; Peter Gray; Uppsala universitet; []
   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

4. 3. Querying Data Providing Web Services

   Författare :Manivasakan Sabesan; Tore Risch; Roberto V. Zicari; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; views of web service operations; web service queries; adaptive parallelization; query optimization; Computer science; 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

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

   Författare :Thanh Truong; Tore Risch; Martin Kersten; Uppsala universitet; []
   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

7. 5. Integrating Visual Data Flow Programming with Data Stream Management

   Författare :Lars Melander; Tore Risch; Sharma Chakravarthy; Uppsala universitet; []
   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
