LEAP - An Extendable Relational Algebra Processor

This note is to announce that beta-version 0.8 of LEAP
has been made available on a number of ftp sites.

LEAP is a relationally complete RDBMS. It offers a
relational algebra based command interpreter, support for
relational structures, indexing using B-trees, hashing
tables and extensive documentation. A source code level
framework for enhancement is incorporated for interested
programmers to further enhance or modify the system.

LEAP has been successfully used as a teaching aid in the
current Databases course at Oxford Brookes University,
England. Students have been encouraged to use the system
to experiment with the relational algebra, and this has
proved both successful and enjoyable for all concerned.

The executable program, which runs under MS-DOS, and its
associated documents/files, is available to all, via
anonymous ftp from:

cmssrv.brookes.ac.uk     /pub/databases
ftp.demon.co.uk          /pub/compsci/databases/leap
micros.hensa.ac.uk       /micros/ibmpc/dos/k/k174

Download the files leap.zip (206k), and leap.txt (1.7k).

LEAP was previously announced on a number of usenet
groups as a relational algebraic relational database
management system (ra_rdbms). LEAP is the latest version.

More information is contained in the distribution files.

A World Wide Web page exists which contains more
information about the system. Please take a look. There
are links to the ftp servers carrying the program, and
more information about the program as a whole:
