Max 5 Simultaneous Users of a Database?

D

David Portwood

In his book "Access VBA Programming for Dummies", page 299, author Alan
Simpson discusses splitting a database into a front end and a back end to
enable simultaneous use. The front end is then distributed to each user "up
to a maximum of five simultaneous users". This seems a very low maximum -
probably not one that I can live with. Is it accurate? Any advice or
suggestions in this regard?

255 (theoretically) not 5. Actual practical limits depend on your network, the
design of the app, and what users are doing. A few dozen though is not unusual
at all and when all factors are just right over a hundred is doable.

Hi David,

It's certainly not the maximum number. Perhaps it is that author's opinion
of how many concurrent users you should have.

I have worked on systems that have had 30 concurrent users...

Hope that helps.

Damian.

It's not an Access limit. It may be the limit on the number of
simultaneous connections to a workstation running a non-server operating
system.

Well five would be safe, but in real life most users report 20-50
depending on the network and design and the amount of user traffic.

I had maybe 50 possible users, but I doubt if it ever got over 25 and I
never experienced a problem related to multi users. It was usually my
programming errors.

The author is officially off my Christmas list. If he had written "5" I
could have believed it was a typo. But he wrote "five" and scared me down to
my toes.

I sold my boss on converting from Excel to Access exactly because I know
Access allows simultaneous access to its tables. But we'll have, typically,
five to ten simultaneous users - at least four data entry people plus
various sups browsing/editing at their whim. And that number will probably
increase in the near future.

I had visions of knocking on my boss' door tomorrow morning and telling her
we couldn't use Access after all - after she'd bought 50 licenses.

Giving the Devil his due, however, the rest of the book seems well written
and very clear. Extremely basic information, of course, which is just what I
need right now.

Umm, well, actually you likely didn't need all fifty licenses. Five or ten licenses
for power users to create their own queries or reports. The rest can use forms and
reports you've created with an Access runtime. You purchase it once (or download
the A2007 version for free when it's available) and you have a license to
redistribute the runtime with your app as much as you want.

This is *wrong*. I've had 25 users in all day long in one of my apps.

Yes. My website is the equivalent of a book.

You have proven that some don't.

Does writing a book make you more intelligent?

Tony, what "a a r o n" says may well be true for any software he might
create, regardless of the development tools. Haven't we said, "If you work
at getting every factor as far from perfect as possible, you can create an
application that won't support even one user."?

lose the training wheels; you fat lazy newbies

leave MDB to the retards and cripples-- like michael kaplan


you dipshits should build a time machnie and go back to the 90s---
that is the last time that MDB was relevent for anything.

Access _ROCKS_
