what difrence between default database and mysql data base ?
Default one is H2 embedded database. The only good thing about it is that it's bundled with the app, so it doesn't require separate installation or configuration. It's good for small number of devices. One disadvantage of H2 database is that it doesn't allow simultaneous access from different system processes, which means that you need to stop Traccar server if you want to edit something manually in the database.
If you need to store data for more than a couple of devices, I would recommend to install MySQL. It's a fully features database engine which means it can handle pretty much any amount of data if configured correctly.
ok well , where can i found the database to use imprt bouton of mysql please , i must install traccar mysql database where can i found it ? pls
