As database administrator, you also have the option to open and edit the name of existing databases. Click Database in the start menu and you will see the following symbol on the right of each database.
When you click to open a database from the database window, you have the option to create a copy of the selected database. Give the copy a name and click "Copy". This window also allows you to delete and change the name of a database.
NOTE: When you change the name of a database, you also change the name to be typed in the field for Database in the log-in window for dRofus. All users in the project must therefore be notified of the change. You must therefore never change the name of a database unless absolutely necessary.
