I work on query processing in databases, and the use of artificial intelligence to boost database performance. Regarding the application of databases, I investigate the potential of collecting the queries first and then derive the database design from them.

Research projects

  • Query-driven database design, integration, and optimization
  • Using modern hardware (FPGAs) to speed up database-query processing
  • Investigate AI methods for the improvement of database technology (e.g. autoencoder)
  • Build a repository of neural-ne

    To test and evaluate a heterogeneous stream-processing system consisting of an FPGA-based systemon-chip and a host, we develop a benchmark called SKYSHARK. It uses real-world data from air-traffic control that is publicly available. These data are enhanced for the purpose of the benchmark without changing their characteristics. They are further enriched with aircraft and airport data. We define 14 queries with respect to the particular requirements of our system. They should be useful for other hardware-accelerated platforms as well. A first evaluation has been done using Apache Flink. We envision a great potential because of the flexibility of the approach.
