Liquid Water: Theory & Experimente revisit datalog with this goal in mind. The focus of the presentation is on the formal extension of the model of distributed datalog and does not consider the implementation or the evaluation of the corresponding system [8].

Exploiting Bounded Treewidth with Datalog (A Survey)uctures is expressible in MSO then this property can also be expressed by means of a monadic datalog program. Moreover, the resulting fragment of datalog can be evaluated in linear time (both with respect to the program size and with respect to the data size). In this survey, we present the main ide
