# The lang/datalog port

## datalog-2.2p0 – deductive database system similar to Prolog

## 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.
