In Chap. 1 we provided an overview of the main reasons for the integration of database and logic programming technologies, and we established a comparison between the main features of relational databases and logic programming languages. Here we will just recall some important aspects of Prolog as a query language; these features essentially enrich the expressive power of classical query languages based on relational algebra or calculus.
