A floor rule R1 is really a floor occasion of One more rule R2 if R1 is the results of a substitution of constants for many of the variables in R2. The Herbrand foundation of the Datalog application will be the set of all ground atoms that can be built Together with the constants showing up in This system.
Its origins date back to the beginning of logic programming, and is often getting used to explain systems, or to make area designs.
