Clipping is a handy way to collect important slides you want to go back to later. In a deductive database system we typically specify rules through a declarative language—a language in which we specify what to achieve rather than how to achieve it.An inference engine (or deduction mechanism) within the system can deduce new facts from the database by interpreting these rules.

DEDUCTIVE DATABASE EXAMPLE • CORAL: CORAL project was developed at the University of Wisconsin in 1988; the idea was to develop a robust deductive database system. Deductive databases reuse many concepts from logic programming; rules and facts specified in the deductive database language Datalog look very similar to those in Prolog.

The data can also be recorded and observed are generally non-numerical in value. Datalog is the language typically used to specify facts, rules and queries in deductive databases. The simplest example of a stratified logic program is that of a deductive database E ∪ I whose predicates are partitioned into extensional predicates, defined by facts E, and intensional predicates, defined in terms of the extensional predicates by facts and rules I.Consider, for example, a network of nodes, some of whose links at any given time may be broken 14.
