The Edit Connections Dialog can be invoked from the Tools -> Edit Connections menu. It defines all the connections which can be selected in the Connect Dialog.
You can create as many connections you want in the edit connections
dialog. All fields except user, password and system properties are
required. The Other Properties text field is used in case you want to pass some
special properties to the database when you want to connect to it.
Note that the name of the connection cannot be changed once it has been
created. All other fields in the connection are editable.
