After Database Splitting, Is It Possible Zo Send A Tabel Into Backend.
Oct 6, 2004
Hallo everybody
I have an Access databse in which I have devided the tables into backend and frontend by using the Database Splitter wizard.
Then if I create any tables in the frontend Access file then thease tables are visible only in the front end of this system , not from other systems if I put the back end in network.
its ok for some tables , but now I have a table which I have to put in the shared backend , but if I cerate in the front end it is visible only in front end and if I create in backend it is visible only in backend.
how to send a table in the front end to backend after database splitting is over, so that I can access this table from other systems.
if it is possible please help me.
Thank you.
Kiran

Hi,
I have been searching for more info on this and found out quite a lot about it; however, I am still wondering how to connect the front ends that will be in different machines to the back end that resides on server.
I know that when you split a database, the wizard asks where to save the first front end. But how about if you have many?
Any help will be very much appreciated.

Hi. I would like to split my database which is used by various people on a shared drive.
Is it possible to specify a relative path to the linked tables in the back end?
Otherwise, if people access the shared drive via different drive letters, it fails.
Also, I like to keep a copy of the database myself. With absolute paths to the back end tables, I can't simply copy both sections from one place to another - as the links fail.
Thanks.

I recently decided to split my database into a front end/back end environment. What I noticed though was a huge slow down in performance. One subform in particular takes 5-8 seconds to load, as opposed to less than a second before the split.
I know that splitting the database comes highly recommended in this forum, but the slowness is unacceptable. I especially want to split the database so I can execute changes quicker.
By the way, I have read several threads that recommend turning off the name autocorrect feature. I did this in the front and back end but did not notice a diference. I also compact/repair the database regularly.
The other thing I tried was creating an MDE file, as I was told they run quicker. Unfortunately, I am told by Access that it cannot be created. I believe from what I have read that I have too many forms that have attached modules.
For now, I am going to merge the database back into one file. But if anyone could offer some advise, I would like to pursue a split again.

I have been given the responsibility for a database that resides on a company network. The Database has been created by using Access 2000 in Windows XP. There are windows folders fro each team that needs use of the database and within these folders is a macro that loads the form for each team. There is a shortcut folder to the Admin Entrance point wher the actual database and tables_be are located. I have looked at both the properties of both these files and both are Access 2000 databases?
The Database called Database( not my choice of name ) contains all the forms, queries, reports,modules etc and the tables are linked to what seems to be the Admin Entrance point. Unfortunately I am unable to see the full link when using linked table manager. This I presume is the tables located in tables_be. The database table_be contains all the tables.
When trying to store the Autonumbering to the database after corruption using a solution kindly supplied by Pat Hartmann by taking a copy of both the database and table_be and working on these I successfully got the autonumbering working.
What do I need to do to successfully implemting these on the network. I have tried to copy the new files back to the network with the same names and in the same location but am getting error messages when I try access some of the forms.
Unfortuately there is no documentation as to how this database has been constructed hence the long winded post.

I split a database and created a backend but now I dont need it and I accidentally deleted the backend while I was updating the file folder and it was on the network so it's gone for good.
Is there a way to reverse splitting a database so it no longer requires the back end?

I have a split database - frontend and back end sitting on a server. If there are only going to be absolute maximum 4 people using this database at a time - is there any good reason for it to remain split.
The reason I ask is that a few people may want to "take it home" to work on it and being non-computer savvy people have a lot of trouble re the concept of linking the front end to the back end.
How do you unsplit a database?

I have a database (already splitted in FE/BE) which Clients use on site.Part of the service we offer is Outsourcing: We do all the capturing and when they login on their side, it downloads the latest BE file for them to use "Read-Only".
However we added a new module in which half of the data on a particular table needs to be completed by the Client.So we need for the table to be splitted in such a way that they can capture their info on the form and when we log in on our side, it has to download the data they entered in the same way as when they login and download the data we captured.
Was thinking about adding a 3rd database file to the mix with just one table and in some way link that table to the existing table for the new module. But the intermediate link I created is not updateble.

I've recently downloaded the Goods template database from Microsoft [URL]. It's basically a inventory, invoice, purchase order system and is enough to fulfill my office needs. However, I seem to be running into an issue when I'm trying to split the database using the built in tool.
The "the database cannot be opened because vba project contained in it cannot be read..." error pops up when I click on "Access Database" button in an attempt to split the database. I also tried to do it manually, but noticed that none of the queries and most of the forms don't show up on the list when I'm trying to import queries, forms, etc.

Hi - I have a front end database that is linked to 2 backend databases. I'd like to add code so that after the splashscreen pops up it checks to see if the front end is linked. If not then asks the user to enter the path for the two backend databases. I need your HELP!!1

A client has had a database in operation for about a year. They requested some updates. I have been trying to figure out an easy way to update table structer with out having the client go into the backend and add a field or two.
I wrote an update program, that copies the table from their backend, and copied it to the updated table and tried to copy it back to thier backend, but since it is in a relationship, it won't let me.
Any suggestions?

Hello.
I have spent the last couple of hours looking through the forums but have managed to get myself really confused. Lots of questions, sorry - if anyone can point me in the right direction with one or two of them, I would be hugely grateful!
I have a database in a shared folder on the network at work. It is due to start being used by users other than myself in future weeks, and I see here that it's sensible to split things into a FE and a BE.
1. My initial problem is that I have a nagging memory of being told that we're not supposed to save anything on the individual computers hard drives. Can a split leave both the BE and the various copies of the FE on the shared drive, or does this negate the reasons for splitting in the first place?
2. Additionally, with little space left on the shared drive itself, it's possible we'll not have the room to put 10+ copies of the FE on it anyway. If I just split the database into the BE and ONE copy of the FE which everyone accesses, will the BE at least be made more secure by the split, even if the FE is still vulnerable, and performance isn't improved?
3. If no sort of split is possible, are there any alternatives to splitting?
Lastly, some questions for if we ARE able to split and put the FE on each computer:
(I would be keeping the BE and the "master" version of the FE on the shared drive. All tables in the BE and queries, reports and forms for the "user interface" in the FE. Hopefully this is roughly what I'm supposed to do).
4. With a split database, what happens with compacting? Presumably the BE of the database can be compacted as normal, but what happens with all the versions of the FE? Does each user have to be responsible for compacting them individually? Does an FE even need compacting if the design is unchanged?
5. Does splitting affect what happens if two people either open or amend a record at the same time, or is that still just governed by the record locks setting in Tools (which would need to be set before splitting presumably)?
6. If the design of the FE changes (but none of the underlying tables, queries etc. are touched), do I just give each user a copy of the new version, or does something more complicated have to happen (ie. does the whole splitting process have to take place again)? What about if new tables are added to the BE, or if existing tables / queries are amended? Can I just issue amended versions of the FE that interacts with the new tables as needed?
7. I have drop down lists and combo boxs in the forms in the FE that use tables to populate them. Will it cause problems that these tables are in the BE - such as impractical amounts of time before combo boxs show their options? (The table has to be in the BE (I think?) because the user updates the content of these tables / combo boxs through one of the other forms in the FE)
Many, many, many thanks if anyone can help me out with any of these.

I split a database (without first making a copy of it) on my local machine and put the front end on a shared network drive. now no one can open any of the forms since the back end is on my machine.
is there a way to undo this or to split the database on the network drive so that users can get in?
i want to avoid having to redo the database from the ground up.

I'm in the middle of developing a database for our engineering group to track projects. I've got a question:
I'm using Runtime because none of our group has MS Access loaded on their system. So, I'm providing a link to the participant to download the free Runtime Software and providing a Shortcut to the database in the shared area.
My question is, when I split the database and provide the users with the front end do they still require runtime? Do I still provide them the link to download the free Runtime software and if so, do I save both the back and front end with the .accdr extension? I'm assuming that since they will have the front end on their systems individually they will no longer require the Shortcut.
The way the system is currently, it seems that only one user is permitted in the database at a time as it is locked out. I would like for more than one user to be able to access the database at a time. I've set the Default Open Mode to Shared so I'm not sure why it gets locked down when a user is accessing it.

Hey guys... I created a reaaaally simple wages calculation program some time ago in VB6. When you click the save button, the records are saved to a .txt file stored in the same directoy as the program itself.
However, I'd like to take this a step further and connect this program with some tables setup in an Access database. I know this has something to do with ADO, right? But not quite sure how to set this up..
Would it be possible to get some guidance on this? If you'd like to see the program, let me know.
Thanks for any input!

How can you stop people editing the data in the backend database from the linked table in the front end?
The back end is passworded but you can still change data manually from the front end.
Can this be stopped?

Hi :)
(A2K format, but running on XP, etc)
I have used Microsoft’s Security FAQ and recommendations on this forum and build a split database; secured with one worgroup file for development and one for customers: what is the most appropriate way to upgrade the backend database content (tables mostly) (as the front-end database can just be replaced) at the customers site?
At the customer there is no development workgroup file, so no permissions to change database objects. I would really like to run sql updates from the new FE database. The solution I currently have devised to go around this problem, involves a lot of manual data moving code, to take care of referential integrity etc. However this approach has a higher risk of creating errors and also takes a lot longer time.
Is there something I have misunderstood of the Security FAQ or recommendation on this forum?
Thanx
:)

I've created a database to track my client information. I've split it into front end and back end databases. Everything there works fine so far.
I have other co-workers who track their own clients who I will be giving this database to. So we will soon have the same database with completely different data stored in them.
If I want to make changes in the future, I should easily be able to change the front end, get them a copy to install, and all should be well.
But what if I want to make changes to the backend? Like if I decide I want to track some completely new data in a separate table on the backend. I won't have the ability to just go out to the central server and change 1 backend database. There may be 10 identically structured backends on 10 different machines that all need the new table added to them, without effecting their unique data in the existing tables.
So, assuming my explaination made sense, is there a way to make backend changes like I'll need to? Or would I have to go to each backend database and manually make the changes?

I have created a db for a nonprofit counseling org. I had created the first half, mostly administrative tasks, called Phase1, and put the BE on a network drive and the FE on multiple users. Now in developing the clinical portion, Phase2, I linked to four of the tables in Phase1 BE file.
Now I tried to split Phase2 the same way as Phase1 and got an error "Subscript out of Range". I think because of already having some external links in it. I checked for the file and Access actually created the BE file for the new phase2, all of the tables are in it minus the four I was linking to. But, access didn't create a FE file. The original still has all of the objects, tables and forms etc. My question is; can I link to the tables in the new BE file even though those tables still exist in the original file?
