1. Databasskydd
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. LÄS MER
2. Optimization and Execution of Complex Scientific Queries
Sammanfattning : Large volumes of data produced and shared within scientific communities are analyzed by many researchers to investigate different scientific theories. Currently the analyses are implemented in traditional programming languages such as C++. LÄS MER
3. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases
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
4. Semantic Web Queries over Scientific Data
Sammanfattning : Semantic Web and Linked Open Data provide a potential platform for interoperability of scientific data, offering a flexible model for providing machine-readable and queryable metadata. However, RDF and SPARQL gained limited adoption within the scientific community, mainly due to the lack of support for managing massive numeric data, along with certain other important features – such as extensibility with user-defined functions, query modularity, and integration with existing environments and workflows.

5. Querying RDF Schema Views of Relational Databases
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
