Re: OpenQM vs. Everything Else

#1

Simply, OpenQM is based on PI/Open, ergo U2...More in with UniVerse
than t'other one...

Go fer it...

Download the "Converting Applications to QM" from the Download site
and read it.... then download more docs as you need/want 'em...

I guess the big questions are:

Is it a virtual machine like D3, a server like U2, jBase, etc. or a
"direct access" set-up like BerkleyDB?

Does it compile to pcode like everything but jBase? I'm guessing NO,
because it has a C API.

Does it have annoying quirks that drove you back to your preferred
MVDBMS?

Can't believe I forgot these:

Are there REMOVE, EREPLACE/CHANGE, PASSLIST statements or their
equivalents? (I know, showing my U2 roots).

It is a PRIME flavour of UV - as long as that is fixed in your mind -
it is excellent. It has far less annoying quirks than all of the other
flavours and a responsive google group.

It does have REMOVE - about the others - read the docs - they are very
comprehensive.

A few answers...

1. Bruce is almost right when he says OpenQM is based on PI/open. Yes,
we share the general syntax/semantics of the Information style
environments but the implementation is totally proprietary.

2. We have a version of QM running here on a Mac under OSX. The only
reason that we have not released it is that we have zero expertise in
how to construct the GUI installer. Having to drop down to a root
terminal session to install a Mac product is not very impressive. All
hints accepted!

3. >Is it a virtual machine like D3, a server like U2, jBase, etc. or
a
"direct access" set-up like BerkleyDB?

Not quite sure of the question here. QM uses a virtual machine
architecture but it is (I believe) very different from D3 and more like
UV in its general style.

4.Does it compile to pcode like everything but jBase? I'm guessing NO,

because it has a C API.

Yes. It has a pcode engine. The C API talks to a server process that
runs pcode.

We are gaining a steady stream of new users. As far as I am aware, no
one has every given up and reverted to their previous environment. We
are very keen to hear about and fix any problems that might cause this.

The open source can be used within the terms of the GPL. We have
published a simple set of guidelines about when the opne source is
appropriate on our web site to help prevent vistis from our lawyers

Perhaps there are, definitely positive, developments that cannot be
posted but can be shared privately.

At the risk of advertising, please note that Cache is fully suppored on
the OS/X operating systems and as such our MV extensions to the product
are too.

I have never understood why we need to apologize for telling people

Has anyone ported it to Windows yet?

The non-open source version of OpenQM runs on Windows and you can run
the Personal Edition on Windows, but I'm pretty nothing has changed in
that only the unix version is open source. --dawn

Re QM on Windows...

The open source is Linux only. Obviously, under the terms of the GPL,
you can do your own Windows port but you will almost certainly end up
spending many times the value of a commercial licence (about US$115 per
user) to do so.

I'm predicting the killer MV development tools are going to be:
QM on Windows with mv.NET and DesignBais.
My understanding is that this is coming soon!
