Reldb was posted to comp.sources about mid-year 1989.  It's built up as
a collection of tools, as opposed to a single huge program.  The usual
operations for doing row, column-extraction and joins of
relational-style tables are all there, along with a plotting program and
some plot(1) filters (including one for X11).

All tables are ascii files. In one sense, these utilities are simply an
extension of awk, join, cut, cat etc, which allows named referencing to
columns. Used together, these tools allow you to do anything you can do
with other dmbs's - sometimes slower and sometimes faster.

We tend to use these programs together in shell scripts, which can then
be made to do whatever you like. 

Interfaces to statistical packages such as SAS, S, BMDP and Glim are
available.

Acknowledgement: Reldb was public domain a workalike of Prelude, sold by
VenturCom, Inc.  Prelude has grown into a much larger system by now. 
Reldb has grown less and in a somewhat different direction.  In general,
though, if you know one, you know the other.
