Sharing a single .mdb and problems associated with it

I am in a situation where my supervisor doesn't want the mdb split
into front end and back ends, as he sees it as being impractical. I
also see it as being impractical, as it will only recieve moderate
usage and the number of records should be around 5000. There will be
around 25 different people using the db, but only a handful at a time.

I am coming across the situation while testing that access says that
the db is corrupt and needs repaired for some users, while it
functions just fine with other users still in the database. What can
be done to alleviate this? If a user changes a global variable, will
it be changed for another user?

Split the app.

No

I would just add to Rick's answer that a common source of frustrating
for Access developers using Global (aka Public variables) is that an
unhandled error will reset all those variable to default values.

There are several approaches to solving that problem - but the bottom
line is that global variables are a "Bad Thing" to be avoided for
several reasons besides this issue.

You could store values in a table or in database properties and use a
class to handle the interface to code that needs those values.

Hi,

Your boss is totally wrong about the practicality of splitting the database.
Keeping it as a monolithic whole will lead to more problems that splitting
it. There will also be issues that arise from splitting it but they are all
solvable.

He has made a decision in your domain that isn't his to make unless he is
taking full responsibility for the fitness and quality of your application.
By that, I mean really taking responsibility as when HIS boss asks why it's
so buggy and hard to use, he will step up and say "It's my fault because I
dictated the design". Would he hire a carpenter to put an addition on his
house and then insist that the carpenter could use neither hammer nor saw?

Is he/she an Access developer? I doubt it, else they would not have made
the statement. They shouldn't care whether or not it's split, just that it
works. It will only work if you split it and provide each user with their
own front end.

Regards,
Keith.

This doesn't happen with MDEs however; and unhandled errors should be
extremely rare anyway. I use lots of public variables and have never seen
a problem with them.

Well, my question has pretty much been answered, and that is that for
multiple people to use an access database concurrently, it has to be
split. I'm a relative novice with Access, so that was the big
question hanging at the back of my mind. I just wasn't able to find a
definative answer to "does it have to be split?" anywhere.
It would 'glitch' after 2 people opened it, but nothing was corrupted,
just access saying that it was corrupt.
Thanks for your responses!

It's not impractical at all, nor is it difficult or time consuming to
implement, and is much more stable. Split the app. You won't regret
it.

We have applications written by JSP/Servlet and ASP.NET. All our future development would be based on ASP.NET. We wants to develop a single user interface so that users would not be aware that some of the modules they are using are implement by JSP or ASP.NET (e.g. no need to login both JSP and ASP.NET applications)? Are there any suggestions to share the session in formation among JSP and ASP.NET, or some single-sign on solution.

I have deployed few Access apps splitting it in Front End and Back End. Our environment uses Win XP SP2 for clients, Win 2k3 for servers and Access 2003. The max. number of clients is about 50 (concurrent users is estimated around 10). Whilst the Back End always lives on a server, I am not quite clear where the Front End should live. I have searched the web and find contradicting views.

Hello everybody! I have just found out that the sharing properties of a single database (mdb file on a network), accessed by 3 users, change depending on the user accessing the database.

Nevertheless, in the computer of the other user, the sharing properties are set to exclusive mode...
