Hey!  FOCUS is ***NOT*** a relational database, it's hierarchical.  The
PC, UNIX, and mainframe versions are ***NOT*** 100% compatible (for eg, the
graphic characters that one can embed in screens to do color stuff on the
PC do quite different things on the Sun... as one might well expect).

I know from personal experience that Informix products run on DOS and UNIX,
and that they advertise an OS/2 product.  Don't know about Windows.  I imagine
that both Oracle and Ingres (and maybe Sybase?) have similar coverage.
The point is that these are all real, relational systems that are based on
SQL standards (more or less) and represent some kind of mainstream.

From my experience with FOCUS, on the other hand, this product was designed
to solve a problem on the mainframe and subsequently ported to PC and UNIX
machines.  It certainly wouldn't be my first choice of package in any
situation not involving prior FOCUS use and mainframes, and it ISN'T RELATIONAL.

Hope this helps.
