Abstract
We examine some problems which arise when extending a relational DBMS to support production rules. First, a rule language compatible with classical relational database languages is presented. This language may be seen as an extension of Datalog with non-clausal conditions, tuple variables, functions and updates. The essential contribution of this chapter is then the introduction of a new rule execution model to generate query answers. This highly parallel model is based on extended Petri Nets known as duplicate free Predicate Transition Nets (PrTN). It is shown that such a model is a useful tool to determine rule program consistency and convergence, and to optimize query processing. An algorithm to move up selections in the presence of recursive rules with function symbols is proposed.
