Abstract

Questo sistema di interrogazione dei dati consiste in un'applicazione software integrata nel software di gestione di un sistema ospite di basi di dati o di information retrieval e di un apparato circuitale adibito al processo della condizione di selezione dei dati contenuta nell'interrogazione dell'utente. L'applicazione software trasforma la, condizione di selezione dei dati in forma processabile dall'apparato circuitale. L'apparato circuitale riceve dal sistema ospite il valore che le singole condizioni elementari dell'interrogazione assumono sui dati di ciascuna registrazione da analizzare e restituisce il valore globale che assume la
