Managing databases can be difficult and due to this reason, phpMyAdmin exist to help you do this. It allows you to see the database in an browser and to easily manipulate the databases tables and records. To access the phpMyadmin interface, you would need to which server the database is located on, followed by the username and password.
The database is accessed via the link of https://phpmyadmin.ovh.net/. Inside of phpMyadmin there should be many tables on the left side. These tables work together to store information about the website itself and to return the information to the website so that it can be displayed. The tables are organised by a prefix, for WordPress the default prefix is wp_. This means that all entries will be categorised together for the same website, in essence this allows us to have multiple websites on the same database as long as we can uniquely specify the table prefix.
The phpMyAdmin has 3 database versions, they consist of the current version and 2 snapshots from 1 day ago and 7 days ago. This will enable you to backup your database manually be exporting the database itself. Naturally the database version should also match the FTP backup time stamp aswell.
For advance phpMyadmin security, you can look to add an additional layer of protection, you can find this at securing links.
