Vincenzo Lattanzio,Giovanni Simonetti on the data complexity. We also consider the issue of . for a circuit model, and study it via logical definability. We then move to the combined complexity of FO, and show that it is much higher than the data complexity. Finally, we investigate an important subclass of FO queries — . — which play a central role in database theory.
