Temporal connectives versus explicit timestamps in temporal query languages flow of time by means of temporal connectives. We study the differences in expressive power between these two approaches. We first consider first-order logic (i. e., the relational calculus). We show that first-order future temporal logic is strictly less powerful than the relational calculus with 作者: largesse 時(shí)間: 2025-3-26 15:53

Temporal connectives versus explicit timestamps in temporal query languages compare augmentations of these languages with temporal left and right moves on the one hand, and with explicit timestamps on the other hand. For example, we show that a version of fixpoint logic with left and right moves lies between the explicit timestamp versions of first-order and fixpoint logic, respectively作者: 擔(dān)心 時(shí)間: 2025-3-28 15:56 作者: STELL 時(shí)間: 2025-3-28 18:44 作者: 使服水土 時(shí)間: 2025-3-29 01:06

On Temporal Grouping modeling approach. Specifically, we address the concern over the lack of an algebra for this paradigm, by presenting such an algebra. In addition, we examine the semantics of two notions, coalescing and restructuring, from the perspective of a comparison between the temporally grouped and temporally ungrouped paradigms.作者: conference 時(shí)間: 2025-3-29 08:14
