    Frontend to Backend Databases


    Hi Forum,

    I split my database into two databases "Frontend" and "Backend". THey are located in my OneDrive. OneDrive duplicates the Backend file in the case of two users trying to save data and/or make changes to the Frontend database at the same. Now I have two Backend files which I need to reconcile the data into one. Are there any preventative measures to ensure duplication doesn't happen.

    Thanks!

    Not familiar with OneDrive so don't know if this will fix, but each user should run their own copy of the frontend and only one person (the developer) should make design changes to either file. Distribute new versions of the frontend to users.

    Users do have their own copy of the Frontend. How do we make sure that all users data are saved into the backend? I'm thinking about 8 people will have their own frontend database and the chances of them entering the database at the same time is very likely. I want to be able to fullproof this. Any suggestions help!

    I have multi-user split database with backend on a normal file server and never had issue of the backend duplicating.

    For possible clue as to what is happening, review:

    What is the file server you use? I may have to use alternatives if OneDrive does not perform like I want it to.

    The server is some dedicated computer managed by IT.

    OneDrive and similar facilities such as DropBox only provide exclusive access to one user at a time - in the same way as Excel works - first user to open can do what they like, subsequent users have to save changes they make to a new file.

    Simply, it is not a suitable host for a back end.

    If your situation is multiple users at multiple locations and they do not all share a common network you will need to look at a different solution for the backend such as SQL Azure (which is sql server). It isn't free, but does not cost a lot - depending on usage perhaps $10-$20/month. Drawback is every user will need a fixed IP (ISP's usually make a small one off charge, perhaps $5-$10) since this is the main firewall against attacks. Providing you are not using lookups, multivalue or calculated fields it is relative easy to upsize. But again not suitable if users are working out of wifi hot spots.

    There is also SharePoint. I don't use it (bad experience when it was first launched) and I don't know whether putting the backend on sharepoint will even work for one user, let alone multiple users. But there are sharepoint lists - basically you convert your tables to lists.

    Other alternatives include using terminal server or citrix - benefit is you can still use your access backend but again, at a cost, possibly a lot more than SQL Azure.

Please reply to this thread with any new information or opinions.
