The interesting point is that it was originally done as a series of
shell scripts (in /rdb) and now is a series of Perl scripts (in RDB)
that implement the key features of relational functions using textual
tables as a relational database system in the Unix sense.  Were I an
Elisp expert (which I'm not), each script could probably be translated
into Elisp and, rather than pipe from stdin to stdout, it could load the
database into an Emacs buffer and then process the result into another
buffer.  *OR*, since RDB is open source, perhaps an Elisp front-end
could be put on it to incorporate it into Org.

Just an idea...
