Process Driven Messaging Service

Process driven messaging service is a way to exchange messages between different systems like computers or phones. For example, when you send a text message to a friend, the service creates a process that takes your message and sends it to your friend’s phone. This is a process driven messaging service. It is a type of computer service that automates the sending and receiving of messages, so that messages don't have to be sent by hand.
