	Aditi

    The Aditi Deductive Database System.  A
   multi-user deductive database system from the Machine
   Intelligence Project at the University of Melbourne.  It
   supports base relations defined by facts (relations in the
   sense of relational databases) and derived relations
   defined by rules that specify how to compute new information
   from old information.

   Both base relations and the rules defining derived relations
   are stored on disk and are accessed as required during query
   evaluation.  The rules defining derived relations are
   expressed in a Prolog-like language, which is also used for
   expressing queries.

   Aditi supports the full structured data capability of Prolog.
   Base relations can store arbitrarily nested terms, for example
   arbitrary length lists, and rules can directly manipulate such
   terms.  Base relations can be indexed with B-trees or
   multi-level signature files.

   Users can access the system through a Motif-based query and
   database administration tool, or through a command line
   interface.  There is also in interface that allows NU-Prolog
   programs to access Aditi in a transparent manner.  Proper
   transaction processing is not supported in this release.

   The beta release runs on SPARC/SunOS4.1.2 and
   MIPS/Irix4.0.
