Abstract

We investigate here functional deductive databases: an extension of DATALOG capable of representing infinite phenomena. Rules in functional deductive databases are Horn and predicates can have arbitrary unary and limited k-ary function symbols in one fixed position. This class is known to be decidable. However, least fixpoints of functional rules may be infinite. We present here a method to finitely represent infinite least fixpoints and infinite query answers as relational specifications. Relational specifications consist of a finite set of tuples and of a finitely specified congruence relation. Our method is applicable to every domain-independent set of functional rules.
