You forgot the recent messages and postings on Requiem which is
a pretty fully functional relational data base implementation
using a derivative of SQL called RQL... it supports everythign
the first posted is looking for and a recent post by Mike
Papazaglou indicates it is public domain and source is available
at a reasonable fee (about $100)... I am replicating Mike's post

================================================================
(from Mike Papazaglou, Requiem co-author)

Many people have recently asked me about the availablity of Requiem.
Requiem (RElational QUery and Update Interactive SystEM) is now 
available as public domain software. It comprise some 17,000 lines of
C code and runs under SUN/Vax Unix. Requiem is a single-user system 
at the moment and offers the following facilities:

- a complete data language,
- view facilities,
- supports automatic foreign key generation and updates,
- provides a program interface in C
- and is easily expandable

the following facilities are under development and will be available 
shortly:

- transaction management,
- a complete C-preprocessor.
- user interface facilities.

Requiem is now available via anonymous ftp. For further information
