Using a Logic Programming Language with Persistence and Contexts

Abstract. This article merges two approaches: one dealing with persistence for logic programs, as provided by a relational database back-end and another which addresses the issues of logic program structuring, by way of the parametric context. We claim that these two can be effectively combined to obtain a language which offers significant gains in expressiveness over previous work. This claim is experimentally backed by the applications that have been developed using these tools.
