Compiling Prolog into SQL

Simple SQL-like cmds

Run "join", "filter", etc cmds from shell or script to perform much of what SQL does. Somewhere, there's a user interface that allows typing of SQL-like cmds directly -- the system creates appropriate pipe farm to run the request. All data files are text. System is not efficient.

Prolog self-compiler with above as object language

Allows creation of basic Prolog-to-csh or Prolog-to-perl systems with only small amt of glue. Full ISO Prolog is -- of course -- not attempted. Compiler generates inefficient code in many cases. Run on grunt desktop for "no worries" scenario.

Basic SQL query tool.

Rough & ready but implements a surprising subset of basic SQL.

Various misc test scripts and logs

At least it proves some things are working. Not for the squeamish.

"Flights" database.

One of the test scripts needs this 1000-line file.

Some basic documentation for above

Should not be needed.
