I actually do possess the access for that ftp take into account this wordpress website and I have to use of its database.

How can i think it is? It does not possess a cpanel cause after i attempt to access www.sampleURL.com/cpanel it shows:

Not Found The asked for URL /cpanel wasn't available on this server.

Can there be every other way?

You should use among phpmyadmin-like tools available. You will get the login data by editing wp-config.php file out of your wordpress root.

Well, you'd interact with the mysql client typically... you will not discover the database by having an FTP client.
