1. 1. Databasskydd

   Författare :Johan Axhamn; Per Jonas Nordell; Thomas Riis; Jens Schovsbo; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; protection of databases; database protection; copyright; database directive; legal protection for databases; intellectual property; unfair competition; databasskydd; upphovsrätt; databasdirektivet; rättsligt skydd för databaser; immaterialrätt; illojal konkurrens; Legal Science; rättsvetenskap;

   Sammanfattning : The capacity to assemble, store, and make available information in databases is ever growing. This development has accelerated in recent decades, driven by the advent and increased use of digital networks. Already at an early stage, it led to demands for legal protection of databases.

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

   Författare :Sanny Syberfeldt; Sten Andler; Jörgen Hansson; Sang H. Son; Alejandro Buchmann; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Computer science; Datalogi; Teknik;

   Sammanfattning : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. LÄS MER

5. 4. A Programming Language for Data Privacy with Accuracy Estimations

   Författare :Elisabet Lobo Vesga; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential Privacy; Functional Programming; Databases; Haskell; Accuracy; Concentration Bounds;

   Sammanfattning : Differential privacy offers a formal framework for reasoning about the privacy and accuracy of computations on private data. It also offers a rich set of building blocks for constructing private data analyses. LÄS MER

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

   Författare :Silvia Stefanova; Tore Risch; Stefan Decker; Uppsala universitet; []
   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.
