relational language - Free On-line Dictionary of Computing (26 May 2007) :

  relational language
  
     <language> Any kind of programming language that specifies
     output in terms of some property and some arguments.  For
     example, if Tom has two brothers, Dick and Harry, a relational
     language will respond to the query "Who is Tom's brother?"
     with either Dick or Harry.  Notice that unlike functional languages
     , relational languages do not require a unique
     output for each predicate/argument pair.  Prolog is the
     best known relational language.
