How to Split Microsoft Access Database?

Read time: 4 minutes

An Access database serves as a versatile repository for Microsoft data, contained within a single file. However, the continuous use of this database can potentially impact its performance, especially when multiple users access it concurrently. Simultaneous usage of the Access database has the potential to hinder its performance and may even lead to data loss over time.

Dividing the database into two separate files is a highly effective solution for enhancing database performance. This process, known as database splitting, results in the creation of two distinct files: the back end and the front end. The back-end files house the tables with a .accdb suffix, while the front-end files encompass all other components, including forms, reports, and macros. Post-splitting, every user gains the capability to exchange data with the connected back-end database, streamlining collaborative work and bolstering overall efficiency.

Splitting Access Database – Benefits

• Faster and efficient operation
• Data is readily available
• Easy data sharing option
• Supports multiple users
• Improves reliability
• Improved performance

The database can be split using the ‘Database Splitter Wizard.’ But we need to keep in mind the following things before working with the tool:

• Splitting a large database is a complex process, so before making such changes you must speak with the developer.
• Make sure that the Access database version you wish to split must be in accordance with the backend database file format. For example, if the back-end database has an .accdb file format, then the Access database version must be compatible with the .accdb file format.
• Always keep a backup copy of the database file. This will make the process risk-free, and the original data is untouched.

1. Make sure that you have created a copy of the original database.
2. Launch MS Access and open the database file.
3. Select Database Tools from the main menu and click on Access Database in the ‘Move Data’ group.
4. Under the Database Splitter dialogue box, click on the button Split Database.
5. On the Create Back-end Database window, write the name for the back-end database file and select the location where you want the file to be saved. Click Split.

Note: Use the‘_be’ suffix for the back-end database name. This way your original database will be saved as front-end, and the back-end database can be identified with the ‘_be’ suffix.
On closing the Access database, you will have the back-end database in the selected folder and the front-end database will be in the original folder.

The manual database splitting method may not be suitable for corrupt or inaccessible Access databases. Additionally, if there are issues with the Database Splitter Wizard, it can potentially compromise original data and result in the loss of crucial files. To mitigate these risks, professional tools like Kernel Access Database Repair offer a reliable solution.
