Dutch-Belgian DataBase Day 2015



The Dutch-Belgian DataBase Day (DBDBD) is a yearly one-day workshop organized in a Belgian or Dutch university, whose general topic is database research. DBDBD invites submissions (1 page abstract) on a broad range of database and database-related topics, including but not limited to data storage and management, theoretical database issues, database performance, data mining, information retrieval, data semantics, querying, ontologies etc. Based on the submissions, the workshop will be organized in different sessions each covering a particular topic.

At DBDBD, junior researchers from the Netherlands and Belgium can present their recent results, and meet senior researchers in the field of databases. It is an excellent opportunity to meet up with your Belgian/Dutch colleagues, and to get informed about the (recent) database-related research performed in Belgian/Dutch universities. The workshop is also open to non-Belgian/Dutch participants (presentations are in English). The workshop consists of oral presentations. There are no printed proceedings. Abstracts of talks will be published on the workshop's website.

The Dutch-Belgian DataBase Day is organized under auspices of SIKS, the Dutch research school for information and knowledge systems. This year, DBDBD is organized by the Database Architectures group of Centrum Wiskunde & Informatica (CWI), the national research institute for mathematics and computer science in the Netherlands, and will be held on Wednesday, December 16, 2015 at CWI in Amsterdam (Netherlands).
