Welcome to the Database Technology Group of the Department of Informatics (IfI) at the University of Zurich.

The research area of the database technology group focuses on data centric systems. A key focus is on issues related to time-varying information, including data models and query languages, query processing, and system architectures. Recent and ongoing research activities of the database technology group include aspects of data warehousing, spatial databases, database migration, schema evolution and versioning, data provenance, and similarity search.

The research approach of the database group has a technological focus and includes the construction of data-centric systems as proof of concept. Our activities include the design and implementation of systems, algorithms, data structures and database languages, system-based experiments, and algorithmic complexity analysis. The emphasis is on theoretically sound results with a solid formal basis that solve actual real-world problems. We develop algorithms and systems to validate, communicate, and disseminate our research results.
