Amichai:
I couldn't login at http://demo.geeex.net, I need a username and a
password... from the looks of it, it does some of what we need, not
necessarily the way we need it. It may or may not be a good departure
point from which a developer might start coding. (Assuming it's free
enough to modify.)
Guy:
Thanks for the 2c+p :-)
I'll start by making an important point, which is that I'm an elected
official whose time is devoted to the political work of the
organization, not to technical issues. In fact, I don't have admin
privileges anywhere. And the person supporting our current app has low
availability unless we contract him specifically for some task. And our
administrative manager's automatic answer about anything tech-related is
"No, let's not change anything, we have too much trouble on our hands as
it is" (which is right about half the time unfortunately).
1. The scaling issue is a significant problem but not the critical one
at this point. We need a sort of a rewrite for other basic design
reasons. But it is indeed possible that an Access rewrite using a real
DB as a backend might work.
2. Yes, I did verify that. But the server will not be more than a
souped-up single PC.
3. So you're not resolving the "web-based or not" dilemma for me... I
will say that there's no specific need for a web-based front-end. The
system only needs to be accessed from our computers, not from anywhere
else. In fact, even a multi-platform frontend is not an absolute
requirement. A Windows client/front-end with a DB-only back-end running
on, well, anything, may be enough at this point. Of course, being
multi-platform is a nice plus. About numbers of records - for daily
tasks you don't need to display a huge amout of data on-screen, but I do
need things like type-ahead find, and sometime you do have a large
number of records with which you need to do something, it just doesn't
involve displaying them.
4. Will try there, thanks. Biased is quite alright, I'm not trying for
the theoretically optimal solution, I'd like to find someone who can
offer me a solution which works, is not overly expensive to
develop/set-up, and can be supported.
