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

7. Main-Memory Query Processing Utilizing External Indexes
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

8. Scalable Validation of Data Streams
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

9. Scalable Parallelization of Expensive Continuous Queries over Massive Data Streams
Abstract : 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. READ MORE

10. Scalable Queries over Log Database Collections
Abstract : 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. READ MORE
