About mysql database for wordpress workspace


when I install and run a mysql database in a wordpress workspace then install phpmyadmin is c9 the default database name for that specific workspace or do I need to create a new database to reflect my current workspace. Just needing to know for when I migrate my database to a live host. Also, if I make several wordpress workspaces etc. will they all be separate mysql databes and phpmyadmin or will there be a they listed in the same phpmyadmin panel under different names
