The Database Systems Group of the Free University of Bozen-Bolzano aims at enhancing current DB technologies to support complex query processing and data analysis, in particular for temporal and spatial data. The group is striving for scalable and efficient algorithms with the goal of embedding them into DBMSs. Our research method combines foundational studies with systems engineering and empirical evaluations. The research is driven by real-world applications in different areas.
