Description

The Datalog package contains a lightweight deductive database system. Queries and database updates are expressed using Datalog—a declarative logic language in which each formula is a function-free Horn clause, and every variable in the head of a clause must appear in the body of the clause. The use of Datalog syntax and an implementation based on tabling intermediate results, ensures that all queries terminate.

    This simple little implementation of a Deductive Database, and the beautiful little Lua nugget within was the key that helped me to begin to grasp Logic Programming concepts. It's a beautiful, powerful and lightweight query language.
