BTW Logo

The conference on Database Systems for Business, Technology and Web (BTW) is the most important database conference in Germany. Since 1985 it serves as a central forum for scientific and industrial exchange, offers demo and student programs as well as tutorials and workshops on various current topics. The relevance of BTW and its development are described by T. Härder and E. Rahm in their article 30 Jahre "Datenbanksysteme für Business, Technologie und Web (2015) as well as A. Blaser in Die BTW im Wandel der Datenbank-Zeiten (1995).

A complete list of previous BTWs can be found on the webpages of the Gesellschaft für Informatik. The conference proceedings can be found at dblp.uni-trier.de.
