You are currently viewing How To Repair Split Database?

When you split an Access database, you segregate the data in two files, i.e., back-end database and front-end database. The back-end database file contains the data tables and table links, whereas the front-end database file contains database objects, such as forms, reports, and queries.

Splitting a database helps reduce the chances of corruption, enhance performance, and data flexibility. However, the split database can still get corrupted due to certain reasons. When the split database gets corrupt, you may face different issues with the database. In this post, we will discuss some effective methods to repair the split database.

Before moving on to repair the access database, you can try the following workarounds. These can help you to determine if the database is actually corrupt or you’re facing issues with the database due to other reasons.

Workaround 1: Check Internet Connection

If multiple users across the network share the split database, network connectivity issues can make the files inaccessible. You can make sure that the internet connection is stable and functioning correctly.

Workaround 2: Check Linked Table Connection and Relink It
