	The CreateDomainNameRequest wraps the request into a DNRequest record, and saves it into the database. The fi rst InvokeMethod activity calls the AddDNRequestToList method that appends the new request into the list of request (that is, the list in the middle of Figure 11 - 19).

4.	The second InvokeMethod activity calls the UpdateDNRequest method that updates the state of the request in the list.
