General :: Split Database - Modify Backend File And Make A New Front End
Jun 12, 2012
So a while back I created a database which I use to keep track of my companies large list of products. It is very simple only 3 tables, 1 query and 1 form. After running into a problem with copying and pasting updates on each computer in the office I decided to split the database on a network drive. This worked for a bit, however I had to add new fields and modify the form, which corrupted the file. Luckily I had a backup before the split.
As far as I could tell all I had to do was modify the backend file and make a new front end. However it seems like it is not as easy as I thought it would be. How do you modify a split database without corrupting the files or using a non-split copy?
I have designed a split database( with back end and front end), I am just wondering what would be the best way to put a password for both of the back and front end.
I have built an Access 2010 split database on my computer and it functions as built. My next step was to copy it to the server at work and test it. I discovered the tables had to be re-linked and so did that. As I have read in the Access World Forums in order to function as a multi-user database a copy of the front end must be placed on the individual workstation with the back end residing on the server, however the hyperlinks in the back end will not function when the copy on the workstation is run. I simply get an unable to open "filename" error pop-up. I can run the server copy and everything functions as built. I know that the hyperlinks require all the files to be in the same folder (relative vs. absolute), but if the back end contains all the hyperlinks why does the location of the front end seem to affect the operation of the back end?
I have (on a company network) a FrontEnd .accde and a backend .accdb - currently ~ 10 users (some over wifi - slow!)The FrontEnd is becoming a rather large file ~ 10 MB and is also becoming slower.I am looking to separate this in to 3 FrontEnd files as to simplify and to lessen the file sizes etc.
My question is - are there any issues around a 3 x FrontEnd databases all connecting to 1 x backend database holding all the tables - over a network?
I have a back end database that i cannot access at the moment. Is it possible to set the link of the tables for the front end application based on the location that the database will be even though i can't see that location now?
Is there any particular reason I would choose to use
DoCmd.RunSQL "insert into...
Versus
CurrentDb.Execute "insert into.... ??
I am using an unbound form on the front end of my database to populate the backend tables (multiple tables). Some forms only have a few fields, while other forms have about 15 fields with 3-4 tables updating.
I am okay using the DoCmn.RunSQL , but I keeping reading on the forum that others chose CurrentDB.Execute and it has me thinking.
My database is stored on a network drive with only on front end.
Hi, as an attempt to improve database performance, I have split a MS Access 2003 database. I have successfully split the database and saved the backend onto the server. My question is, where is the front end. or do I have to create it?
I have a client that is using a split database. I am working on an update to the program and need to transfer a table to the backend that has the correct structure and information included in it. My thoughts are to make a one time use program that transfers the table to the backend. I have seen DoCmd.TransferDatabase and DoCmd.CopyObject as possible ways to go.
I have a 2007 back-end db on a network share and around 15 regular users who access it through their own front-end db/interface. One user on Windows 7 is able to launch and use his front-end copy fine except when he goes to launch one form for data entry.
This form clocks and freezes the entire application. I sat with him and was able to determine that the issue is that the form_load code is never running. He clicks on the button to launch the form (done in vba) and the code never runs. If he opens the form in design view first then changes to form view, the code runs fine and there are no issues. This is his present work-around, but I had to give him an unlocked FE copy to pull it off (not ideal!).
I tried this with him on different PCs, with different front-end copies, and even in the back-end copy. Same result each time. None of the other users have this issue, and he can replicate this issue on different PCs. I'm at a loss for what might be causing this since it really seems so user-specific.
I am trying to create a navigation form on a split database with front end and back end.But Access is not letting me drag forms or reports into the navigation form. Why?
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.
I want to deploy an access database at a small office with 5 computers, small network. However I do not intend to create a server in order to have a domain etc. Operating system is win 8.1 pro. Should I use a homegroup or workgroup ? Would it require password in case of workgroup? Which is a recommended way to setup this and keep some security like a guest cant access these files?
I've developed a database that was working fine until I split it to use in a network enviroment. The problem is a make-table query that now make it's table in the front end instead of the back-end. I need to run a make-table query because the query uses a custom function which then causes errors when the query is accessed by a web form that I use.
The only way I thought of getting round it was to create a permanent table in the back-end which is cleared every time and an append query used to populate it.
I was successfully using a front end and back end setup for the past two years. Today I needed to push through some changes and "deactivate" the previous back end database and setup a new back end database. The new back end database has been sent; however the front end is not recognizing the back end database anymore. I need to re-link the existing front end to the back end database - I cannot import the front end into a "fresh" file because I put a password on the VBA Editor.
How do I hide or disable the File tab in Access 2010 on my front ends?
The file tab being present allows end user to get into Privacy Options and Printing. Printing is okay if I could disable the Privacy Options for end users, then it wouldn't matter if they have access to the File Tab.
Objective?: I'm attempting to change the file location of the back end portion of my split database.
What I've done so far: I've used the linked table manager to update the back end location of all tables in the front end portion of the database.
Symptoms: When making a change to the OLD back end: If I change the name or move the old back end and then try to re-open the front end, Access opens as if I'm opening the application itself without any database associated with it until I restore the OLD back end to its appropriate state.
When making a change to the NEW back end: If I change the name or move the new Back end and then try to re-open the front end, I get a: "Could not find file" error message until I restore the new back end to it's appropriate state.
I've just discovered a query that I think put me one step closer to resolving this issue. [URL] .....
When I run this query:
Code: SELECT MSysObjects.Database FROM MSysObjects GROUP BY MSysObjects.Database, MSysObjects.Type HAVING (((MSysObjects.Type) In (4,6)));
It returns 2 results: 1. The path of my old back end 2. The path of my new back end.
Unfortunately I'm not able to update the values from the Datasheet, but this does confirm to me that the old back end is still some how being used by the front end even after my tables have all been updated.
If the user clicks on this link then the respective file should be open..I don't want the front end users to see the entire path. So, I would like to have the names as 1234.pdf in the location column instead of M:New1234.pdf. Is it possible to hide the entire path in the backend and show only the name of the file. so that if users click on 1234.pdf then the file needs to open.
We have a MS Access Application. It involves authentication as well. I split the database and created this db_be file. I deleted this. Now I'm not able to login into this Application.
I'd like to to import some large oracle tables from a remote server using "DoCmd.TransferDatabase..." on a daily basis. Currently, the system works, but my database is getting quite large (800 Mb) and I'd like to split off the tables to a back end database.
Is there a way to import directly to the back end database? The postings that I've seen seem to imply that one must first import the tables into my front end, then export them into the back end. Does that sound correct?
I'm at home right now, but will give it a try when I get to work. It just seems like there's got to be a more direct way!
