From Simple Wiki

Microsoft Access databases can be used for a number of functions in SimpleIndex.

When using Access as a back-end database for Multi User processing and search, it is recommended for no more than 5 simultaneous users or 500,000 document records. Using Access with too many users or records can significantly impact performance.

SQL Server, MySQL or Oracle database servers should be used instead of Access for projects with any significant volume.

You can still use Access to view and edit the data on those servers via linked tables.
