If I want to distribute a front end to connect with a MySQL back end ... do I need to set up the system DSN on each workstation that will be using the front end?

I have a "Read only" frontend and Backend as 2 different files on the LAN shared drive.
i have around 50 users logging on to this to view information (No editing allowed by the user).
I read on some of the previous forums that Multiuser frontend does not work that well. I want to know if this is true even if my users are in read only mode??? I have tried with 3 users and it works with out a hitch. i just want to be sure before i roll out this to the entire 50users.
thanks

If I have an MS Access frontend that connects to an MS Access backend, is there a way to hide/permission block the pathway to the backend's folder but still allow access via the frontend db?
Right now I can't dedicate a server to a more "secure" form of DB or anything like that so I'm stuck with MS Access for now. I just don't want someone looking at, say, a link table path and then navigating to that folder and getting access to backend information.
Hi people,
Does anyone knows the difference between frontend and backend database? I look 4ward to hearing from any database expert.

I am evaluating a program for the use of a customer. It's a VB frontend attached to an Access database.
The backend has no relationships. No table in the backend even has a primary key.
My question: Is this scenario acceptable in any way?
I tend to think not, but am unsure whether the design of the frontend application establishes relationships "on the fly". Even if so, the fact that there are no primary keys makes me think I should dismiss this application out of hand.
Thanks
I am very good at excel and can program macros. I am being asked to build something in access for my company, or at least manage a build. So here is my question... If we build it without both a front and back end, is it easier to take what you have and switch it to a front and back end? Also, when and why is it better?
View 4 Replies View RelatedOn my development machine everything works great, but I know that I'm going to run into problems with distribution.
I don't think there is a way, but I'll ask. Is there any way to get around not having to install the ODBC MySQL drivers on each computer? One of the reasons I'm migrating to MySQL for a backend is the fact that I'll be going from 10 users to 150 users, each of which has a "locked down" PC, which would mean logging into each with Admin rights to install the driver. Not an impossible task, but a pain.
Is is possible to have a "shared" source for the driver? I have only a rudimentary understanding of that process.
Thanks in advance for any help that someone can provide, or some answers pointing me in the right direction.
I have a multi user database in Access 2000 that is on a server. The individual users have shortcuts pointing towards the server instance. One user and one user only when opening the shortcut gets the error "you do not have exclusive rights to the database" .
All other users can enter the database with no error box. I have checked the advanced setting under options and they are correct. Ironically if you go to start and open access then navigate to the database shortcut. It opens with no error.
I created a database for multiple users, it seems only one user can be in database at a time. Is there a property that allows multiple users to simultaneously use database. My record locks property is no. Is there some other property that needs to be set ??

View 3 Replies View RelatedWe are encountering severe performance problems when running our access database on our Network.
Symptom:
Huge drop off in performance when 2nd and subsequent users refresh links to chosen back end database. If the database is opened by another users front end database.
Takes up to 10 minutes to refresh the links to 120 tables in Back-end MDB database.
The system is designed as a split front and backend Access database. The back-end Data MDB database is located on a Windows 2000 server.
The first time a user logs on they are required to locate and Re- Link the tables from the back-end database which holds data for the current year. If they wish to work on another year they re-link the tables from the relevant back end database.
When running locally the Front end takes between 5 and 10 seconds to refresh ALL the links to around 130 tables.
When the back end is on a network drive the process takes about twice as long. But is still quick.
If another user has the file open via their own (locally held) front end, then the refresh link process takes between 5 and 10 seconds PER TABLE !!
This means that that it takes up to 10 minutes to complete the re-link.
Same behaviour if using Linked table Manager or refresh links using code
As soon as second user logs out of database the refresh link process speeds up.
The behaviour has been observed on a variety of servers and customer networks.
General data access is also much slower after 2nd user - but just about bearable. Data files are small – few records – occupy 7mb on disk.
Development Platforms – Windows XP / 200 clients, Windows 2000 Server hosts the back end database.
Front end is Access XP (MDB or MDE File) with al the latest service packs and security updates installed.
We have experienced this problem with a number of different systems running in various environments. But this wasn’t a problem with the old Access 1 database
HELP! Access should be able to support 10 – 20 users - we can barely run 2!
I have created a form that I want to share with other people. They will never add or change any of the data - they will only use the form as an information source. I need to be able to access the database to add/change information.
What is the best way to do this?
Hi Experts,
I am trying to develop a multiuser database. I heard that in a multiuser setup the back end should be on the network and front end on the users machines. Could anyone please explain what is these back end front ends and how should I set it up.
And one more (silly) question... Do we really need MS Access to be installed in the users machines in order to do this?
Any help is appretiated..
Thanks,

I have a database split with a frontend (FE) and backend (BE). Both reside on our network. I give a copy of the FE to all users. The FE is linked to itself so if I make a change to the network copy the next time a user opens theirs it tells them to close down and it recopies itself. This works really good. The problem we're having is people going and making a shortcut to the networked FE. So WHENEVER they open their FE everyone gets a message saying to close and recopy. The database is about 10mb but for someone across with a slow intranet connection it can take a bit to download. I'm looking ways to prevent users from accessing the networked FE. Can you simply hide it?
Thanks,
DT
Hi!
I´ve just made a frontend backend solution with a db i Access2002.
I made this because my users 5 persons have a booking system wich they use at tehe same time.
But the db locks all the time... I thougt we would get rid of that problem now.
Is there something I have to check?
I have some lookup tables, can this cause this kind of trouble?
Jack
A simple personal database created by me is to be deployed on a home network having two PCs. I did splitting to FE and BE. The BE shows only tables. I would like to have the guidance of experts in this forum for the following:
1. Whether BE to be copied first in the host PC?
2. FE to be copied in the other PC?
3. After copying the Access DB how to link FE and BE between the two PCs?
4. Whether data entry, edit, search etc. possible from both the PCs?
5. If I test with dummy records, how do I delete dummy records, from BE or FE?
Shall be grateful for help.
I have an Access front end and backend right now, however when I made the backend I made it so that Access stores the attachments in the backend instead of a path to the backend. Now the database is growing rapidly and I need to migrate to a MySQL backend. I'm not sure how this will work with the attachments though? I definitely want to just store paths to the attachments in the MySQL database. Whats the best way to do this?
View 7 Replies View RelatedHi,
I'm wondering about the following.
If I would have a backend table with the data kept in tables and a frontend database with forms and reports and queries etc. and linked tables to the backend db, what would be the right way to secure both.
In my situation I have salary information in some of the tables, which should not be wide open to the holy world. I also need to restrict the access of some queries and forms in the frontend database to different users. That means I need to set up a secured frontend database with different usergroups having different object permissions. So in that frontend database the Users Group and the Admin User do not have any permissions any more. Thats why I created a shortcut where I kept the database and workgroup information in the target. Every user needs to open the database via the shortcut.
Unfortunately I was not able to secure both the backend and the frontend database, because the linked tables in the frontend db are only pointing to a database not to a shortcut. Because the backend database is secured as well (no permission to Admin and Users any more) it can't be opened directly - only by shortcut.
Am I right that there is obviously no possibility to have a secured backend and frontend db via the Jet database engine and Access?
I hope somebody can answer my questions. At least I know that I can't do anything else and I did not something wrong ;)
Wondering if anyone had tried this yet, and if so, encountered any problems. I have a few existing DB's in the office. Split with backend on server in mdb format. I am now using both 2003 and 2007... BUT.. Now that the runtime is out I would like to make my future updates in 2007. So the question is... Has anyone used a 2007 file format frontend with a 2000 to 2003 file format backend? I understand that the new field properties wouldn't be available in the mdb backend, but besides that, would they still link properly?Thanks
View 1 Replies View RelatedI created a database a few years ago and it has been working well. This database is split.
Recently I started to update the front end based on user feedback and I am adding some queries.
I am noticing that sometimes I try to create a new query and Access tells me that the tables that are involved in the query are not related. Sure enough if I check in the front end, the table relationships are not the same as those in the back end and while the table relationships I need exist in the back end, they do not in the front end.
While the relationships were initially created in the unsplit database, it is possible that I added some of them later during past development/updating processes when the database was already split. This is the only reason I can think of for them to be different.
When I add a relationship in the back end (new table or bug fix) do I also need to add it to the front end if the database is split? if not, why would they be different? What kind of issues can this create?
I have a backend-database on a network disk shared by 6 users. All users have a frontend client wich they use to administer the datebase. Everything in the frontend looks ok and they can query the latest data. However if I open up the backend database tables nothing has been updated since the middle of december. If i make a copy of the backend I can open it up and create new posts with ID-numbers that has already been taken by the frontend.
Ofcourse I have doublechecked that the clients are connected to the right backend file (there's only on backend file in the directory).
Hello everyone,
I was looking for a great way to link and relink BackEnd to FrontEnd and I sort of found it.
Bob larson build a great extensive tool to autoupdate backend en master frontend. You can find his great post here: http://www.access-programmers.co.uk/forums/showthread.php?t=111132&highlight=back+end
Here is my problem or wish is more appropriate.
I just want to relink the backend and if the backend isnt found I want to select it using the filedialog.
Who can help me...
Perhaps you can Bob???
I included the file
I realy hope that you can help me guys.
On a webserver certian files are stored above the root directory. Therefor the user of the website can never access those files directly. But he is utlizing that file.
For example:
We use Hotmail to see our mails. but we never download the complete database.
So is there a method that we can secure the backend using roaming profiles or something else so the user has a link to the backend but cant directly access the backend.
Could someone please help me?
At work we have a website with a mysql database attached to it. It keeps data such as customer name address postcode contact id etc.
Currently our main database is made in access.
I need to transfer data from the website database (which is in mysql) to our access database. And would like this to happen regulary. We have been quoted £1800 for someone to do this!
As this is a new job i would like to be able to do this myself, is it hard to do?
Could someone provide me with some information of how to do this? or where to start.
Much appriciated.
Hi There,
Whereabouts would I change the date format from the access database from yyyymmdd ?
I am trying to convert this table from access into mysql, and when I ouput to a csv file the date is in access.
Many Thanks
Chris
