 There is a straightforward connection between the teams of team semantics and the relations studied in relational database theory: given a team \(X\) and a tuple of variables \(\vec v = v_1 \ldots v_k\) occurring in its assignments, it is possible to define the relation \(X(\vec v) = \{\langle s(v_1), \ldots, s(v_n)\rangle : s \in X\}\). Furthermore, the dependency atoms studied in dependence logic and its variants are analogous to – and in many cases, derived from – dependencies considered in database theory such as functional dependencies (Väänänen 2007a), multivalued dependencies (Engström 2012), and inclusion and exclusion dependencies (Galliani 2012). The relationship between dependence logic and database theory contributed not only to the further development of dependence logic, but also to that of database theory: for instance, in Hannula &amp; Kontinen 2016 a finite axiomatization of the unrestricted implication problem for inclusion, functional, and embedded multivalued database-theoretic dependencies was found through the study of a similar problem within the context of team semantics.
