Access2MySQL Sync Description:

Access2MySQL Sync Convertor/Synchronizer is an application which allows easily convert and syncronize Microsoft Access (MDB) databases to MySQL and vice versa, unlike other similar tools, which commonly perform only one-way conversion. The program is extremely easy to use, it is implemented like a common wizard-like application, so even an unexperienced user will be able to work with it.
Database synchronization is very useful when updating a database from another one or adding data from several source DBs to only one destination DB (special emphasis is laid on MS Access to MS Access synchronization).
