2. 1. Main-Memory Query Processing Utilizing External Indexes

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

   Abstract : 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. READ MORE

4. 2. Architecting Smart Home Environments for Healthcare : A Database-Centric Approach

   Author : Wagner Ourique de Morais; Bertil Svensson; Nicholas Wickström; Diego López-de-Ipiña González-de-Artaza; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Smart environments; system architectures; active databases; in-database processing; ambient assisted living;

   Abstract : The development of system architectures and applications for smart homes and ambient assisted living has been the main activity of a number of academic and industrial research projects around the world. Existing system architectures for smart environments usually employ different architectural styles in a multi-layer logical architecture to support the integration and interoperation of heterogeneous hardware and software technologies, which are subsequently used to provide two major functionalities: monitoring and assistance.

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

   Author : Silvia Stefanova; Tore Risch; Stefan Decker; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

6. 4. Scalable Validation of Data Streams

   Author : Cheng Xu; Tore Risch; Byung-Suk Lee; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Data Stream Management; Distributed Data Stream Processing; Data Stream Validation; Anomaly Detection; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : In manufacturing industries, sensors are often installed on industrial equipment generating high volumes of data in real-time. For shortening the machine downtime and reducing maintenance costs, it is critical to analyze efficiently this kind of streams in order to detect abnormal behavior of equipment. READ MORE

7. 5. Scalable Data Management for Internet of Things

   Author : Khalid Mahmood; Tore Risch; Kjell Orsborn; Georgios J Fakas; Erik Zeitler; Vera Goebel; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE
