We outline a call to action for promoting empiricism in data quality research. The action points result from an analysis of the landscape of data quality research. The landscape …
Equality-generating dependencies (EGDs) allow to fully exploit the power of existential quantification in ontological reasoning settings modeled via Tuple-Generating …
We propose a probabilistic approach to the problem of schema mapping. Our approach is declarative, scalable, and extensible. It builds upon recent results in both schema mapping …
Datalog^ E is the extension of Datalog with existential quantification. While its high expressive power, underpinned by a simple syntax and the support for full recursion …

Recent years witnessed a rising interest towards Datalog-based ontological reasoning systems, both in academia and industry. These systems adopt languages, often shared …

This issue starts with the Database Principles column presenting an article by ten Cate and colleagues on algorithms for solving the fitting problem for conjunctive queries. The fitting …
