What Causes Access 2007 Database Corruption in Multi-user Environment?

When using an Access database in a multi-user environment, the database file (.mdb or .accdb) is stored on a shared network folder, allowing multiple users to access that file simultaneously. The users can also modify the shared database records. But, multiple users changing the data at the same time can corrupt the database and make its data inaccessible.

Preventing Access 2007 Database Corruption in Multi-user Environment

Once the Access database is repaired, you must split the database into a back-end database (containing tables) and a front-end database (containing database objects). Let’s understand why:

The back-end database is stored on a shared network drive and can be linked to the front-end database stored locally on a user’s computer. By distributing the front-end database, you can allow users to interact with the local copy of the front-end database instead of the network shared file. Meaning, users can make changes in the local database copy, preventing them from making any edits or modifications to the server’s shared database. This helps avoid the shared database from becoming corrupt.

You can split an Access database by using the Access built-in ‘Database Splitter’ tool. To access this tool, you need to click on Database Tools and select the Access Database option from Move Data section. Once the ‘Database Splitter’ dialog box opens, click Split to begin the splitting process.
