1. 1. Querying Mediated Web Services

   Detta är en avhandling från Uppsala : Department of Information Technology, Uppsala University

   Författare :Manivasakan Sabesan; Uppsala universitet.; [2007]
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; query processing; mediated web services;

   Sammanfattning : Web services provide a framework for data interchange between applications by incorporating standards such as XMLSchema, WSDL, SOAP, HTTP etc. They define operations to be invoked over a network to perform the actions. These operations are described publicly in a WSDL document with the data types of their argument and result. LÄS MER

3. 2. Scalable Parallelization of Expensive Continuous Queries over Massive Data Streams

   Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

   Författare :Erik Zeitler; Uppsala universitet.; [2011]
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIKVETENSKAP; TECHNOLOGY; Natural Sciences Computer and Information Science Computer Science; Naturvetenskap Data- och informationsvetenskap Datavetenskap datalogi ; Natural Sciences Computer and Information Science Computer Science; Naturvetenskap Data- och informationsvetenskap Datavetenskap datalogi ; Computer Science with specialization in Database Technology; Datavetenskap med inriktning mot databasteknik;

   Sammanfattning : Numerous applications in for example science, engineering, and financial analysis increasingly require online analysis over streaming data. These data streams are often of such a high rate that saving them to disk is not desirable or feasible. Therefore, search and analysis must be performed directly over the data in motion. LÄS MER

4. 3. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

   Detta är en avhandling från Linköping : Linköping university

   Författare :Sanny Syberfeldt; Institutionen för datavetenskap.; Tekniska högskolan.; Högskolan i Skövde.; Högskolan i Skövde.; Högskolan i Skövde.; [2007]
   Nyckelord :Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Technology; Teknik;

   Sammanfattning : In this thesis a replication protocol – PRiDe – is presented, whichsupports optimistic replication in distributed real-time databases withdeterministic detection and forward resolution of transaction conflicts. Theprotocol is designed to emphasize node autonomy, allowing individualapplications to proceed without being affected by distributed operation. LÄS MER

5. 4. Querying RDF Schema Views of Relational Databases

   Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

   Författare :Johan Petrini; Uppsala universitet.; Uppsala universitet.; [2008]
   Nyckelord :query processing; partial evaluation; rdf; rdf schema; view; relational databases; semantic web;

   Sammanfattning : The amount of data found on the web today and its lack of semantics makes it increasingly harder to retrieve a particular piece of information. With the Resource Description Framework (RDF) every piece of information can be annotated with properties describing its semantics. LÄS MER
