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 2021 will be held in Delft, The Netherlands online. Due to the cooperation between SIKS and the

At DBDBD 2021, junior and senior researchers from the Netherlands and Belgium can present their recent results, and meet senior researchers in the field of data management. 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 consists of poster presentations. There are no printed proceedings. Abstracts of oral and poster presentations will be published on the DBDBD 2021 website.

We invite 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. See the submission guidelines for further details.

This year, DBDBD is organized by the data management team, of the Web Information Systems group at TU Delft.

Who-is-Who of Dutch-Belgium Database Groups

One of the core goals of DBDBD is to get to know your fellow database researchers better. To make this easier, we will have a new special session this year: the Who-is-Who-Session. For this session, we kindly ask every group in The Netherlands or Belgium who participating at DBDBD to prepare a very brief presentation (5 slides max).
