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}/{Irix}4.0.
