Connections are accessed by clicking the gear icon 
in the upper right hand corner of the page and clicking on Connections.
Once on the connections page, find the connection you want to delete and move your mouse over the connection to reveal the controls. Then click the delete button.
Once the delete button is clicked, you will be prompted to confirm your deletion. To finish deleting the database connection, click the "Delete Connection" button.
If the connection is assigned to any actions or filters the deletion will be terminated and the user will receive an error message.
Once deleted you will be given a confirmation that the target connection was deleted.
