Dennis Walkenhorst,Maximilian Rufin this framework, we consider a class of “single pass-evaluable” selection operations. We show how such selection operations can be succinctly expressed by programs that use only very simple positive existential selections. Also, a syntactic criterion is developed for the . of two such positive exi

First, a formalization of a model-theoretic semantics of updates is provided: the notions of . and . are introduced to characterize the various cases. Then, a proof-theoretic approach, based on a variant of resolution integrated with the chase procedure, is defined, showi

Often the query language allows a user to navigate from object to object by following a property value path. In this paper, we consider the combination of three forms of constraints over complex object types: equations, fun
