      Production rules in database systems have been used mostly for
      integrity-related issues (e.g., derived data maintenance,
      authority checking and constraint verification).  This paper
      analyzes the need for using production rules in geographic
      information systems, for a special family of
      applications---utility management systems.  This framework is
      applied to a real life large scale application---the development
      of an integrated database system for the maintenance and
      expansion of the telephone network in Brazil.
