In response to a recent quety about DBMS's:

See UNIX REVIEW Dec/Jan and Feb/March 1984 for a two part article by John 
Roland reviewing UNIX DBMS's. 

In addition to Ingres, Oracle, Informix, Unify and Mistress you should 
consider the RUBIX DBMS ( which is reviewed in the above article ) . 

RUBIX features include: 

1. Excellent integration with UNIX (the RUBIX command language operates at 
   the shell level, not under a separate monitor). 

2. Complete set of tools for loading/unloading and updating databases from/to 
   ASCII files. 

3. Two relational editors (one line oriented like ed and one full screen). 

4. A forms handler/application manager called PREFIX which has a Multiplan- 
   like interface. 

5. A relational programming language with both an interpreter and a compiler 
   which generates C as an intermediate step (can call C routines or generate 
   functions and subroutines which are C callable). 

6. A very complete C language interface (over 100 functions including functions 
   to access forms used by PREFIX). 

8. Updatable views which provide access to joins, selections and projections 
   of any number of relations through a single view name. 

9. A database environment controlled through the shell environment including a 
   PATH variable to support automatic access to multiple databases from one 
   directory. 

RUBIX has not been mass marketed (very little advertising); it has been sold
mainly to manufacturers (Fortune Systems has just released RUBIX for the
Fortune 32:16), OEM'S and VARS, and (recently) 1000+ copies have been
installed in several DoD agencies.  RUBIX (more recently) was demo'ed
in the AT&T booth at Comdex, Atlanta on the 3B2.

The RUBIX people are:

                        Infosystems Technology, Inc. 
                              6301 Ivy Lane 
                                Suite 714 
                            Greenbelt, MD 20770
