• Access does not support replication and does not support multi-source or source-replica replication. MySQL utilises a fine-grained authorisation concept for user notions. However, Access does not embrace user notions, despite the fact that until Access 2003, there was simple user-level security built-in.
• MS Access lacks a partitioning functionality, but MySQL supports composite and range partitioning. MySQL is free and open source, therefore there are no hidden costs. The MS Access database is better suited to desktop use with a modest number of concurrent users.
• Microsoft Access is a useful tool for creating a low-cost relational database because to its drag-and-drop capabilities. As a result, it can be used by businesses to develop databases for marketing campaign measurement when they don't have the funds to pay a data architect.
• When using the non-transactional MyISAM engine, MySQL is a very fast database to read, but it can cause integrity issues in high-concurrency applications when editing.
