A few weeks back I asked on behalf of a colleague for info about 
Object-Oriented Databases (preferably freebie !)  Many thanks to 
all those who replied.  Here is the summary of responses.
-----------

The consensus of opinion with regard to OODB's was that freebies
were v. unlikely to be available. Many persons described the
subject of OODB's as "young enough that no industrially useable
high quality system exist" and that the available dB's were
"various prototypes in different states of maturation".
 
However, some interesting products were suggested. On the cheap
side of things Intermedia ($150 on Mac.) and Observer(~$80 from
Brown University) were detailed. Has anyone used these systems?
 
Commercial databases quoted included:-
 G-BASE (GRAPHAEL), Gem-Store(ONTOLOGIC), Static(Symbolics),
 VBase (SERVIO LOGIC) and Generis (DSL).
 
dB's from recent research topics detailed included:-
 AVANCE(Stockholm Uni.), GARDEN(Brown Uni.), JASMINE(Fujitsu/AIST
 /MITI), LOB(Compiegne Uni.), OBJFADS/POSTGRES(Berkekey) and
 ORION (MCC).
 
Other suggestions involved writing a dB from scratch using an
OO language (Smalltalk,C++ etc.) or else using a toolkit like
KEE or ART.
 
A number of conclusions are thus drawn. The requirement, just to
remind us, is to use an ooedb as a tool for implementing a conceptual
schema etc... The choice is clear. Either write it myself or else
convince others that it is worth investing of the order of $xK ;
where x is an integer, to buy an existing system that is not
exceptionally established.
 
Any comments/suggestions.
