We investigate the expressive power of implicit temporal query languages. The initial motivation was refining the results of [1] and enrich them with comparison to µTL [17]. Thus, we address two classes of temporal query languages: µTL-like languages based on TL and T-WHILE-like languages based on WHILE. We provide a two-level hierarchy (w.r.t. expressive power) for these temporal query languages. One of the contributions solves an open problem: the relative expressivity of µTL and T-FIXPOINT [1, 11]. |
