Dont know much about comparative performance or user interfaces etc.,
but:
The IDM 500 series (at least) sales literature boasts of 'using
these host computers':
DEC VAX, with VMS, Unix
DEC PDP, with RSX, RSTS
IBM 370, 43xx, 308x, 303x with VM-CMS
ATT 3B/5, 3B/20
Prime, Honeywell, Control Data, IBM PC, Apollo, etc. etc.
Apparently, using a multitude of interfaces on the IDM, you can
connect the same IDM to different hosts at the same time. The
interfaces include: IEEE-488, RS232C, Ethernet, IBM Block Multiplexer
channels (is the last one a different type or uses one of the previous
three ??).
It is not very clear from the literature, although implied, that the
host-resident software is supplied by B-L.
The RS-300 Series probably offers slightly different capabilities.
They do mention VMS, RSX, PC-MS/DOS, AOS/VS and 'a wide selection
of Development Software (4GLs, AI, etc.)'. Again, I presume that
they supply the latter.
BTW: If you find any interesting info outside this conf, I would
really appreciate it if you can share it with me. Thanks

| The IDM is a backend database machine. It can be hosted by several
vendor's products. Ours include PDP,VAX,ULTRIX,VMS. In the near
future it will be an addressable DECNet node (VMS).
There are many products for accessing the Britton Lee. B-L has IDL
(QUEL),SQL,other tools. HDR Systems has SQL and other tools. Dimension
has FREEFORM (application generator). All software of this nature
executes on the host.
The storage capacity is approaching 120G (I would need to check
this to be certain) I am not sure if I still have copies of benchmarks,
however, the response of the IDM has never been a problem in my
experience. The performance problems I have encountered have been
with the host.
I have worked with IDMs for about 3 years and have frequent contact
with the company. If you could be more specific about the info needed
I would be happy to help if I can.
