If each atom in the body of the ground instance is within the list of recognized facts, then The top atom is included for the list of regarded information. This method is recurring until finally a hard and fast position is achieved, and no more specifics could be deduced. Naïve analysis provides your entire small design of the program.[seven]
Datalog is unique in that it's based on policies instead of strategies. Which means you explain associations amongst data in lieu of compose instructions for manipulating it. This results in additional concise and maintainable code, as well as far more successful processing of queries.
Particularly, for recursive queries or fastened-depth graph exploration, wherever datalog is much less complicated than SQL, although the recursive Prevalent Table Expressions are already not too long ago optimised in modern-day databases engines to cater for real-life scenarii.

The Herbrand design of a Datalog method may be the smallest subset of your Herbrand base this sort of that, for every floor occasion of each rule in This system, if the atoms in the human body in the rule are from the established, then so is The top.[five] The design-theoretic semantics outline the small Herbrand design to get the meaning of the program.
