HTTPS is always available Messages can be stored into any format ODBC table inserts can store messages
directly into a database
Message Acknowledgement
Messages are acknowledged in real time Message acknowledgement can include
data specific responses from an interaction with a database
Acknowledgement does not require the sending system to have a message server
