How do enterprise nervous systems differ from past IT system architectures?

What will be an ideal response?

1. It is message based, which means that applications, devices, and people communicate with each other via messages. As the Internet has shown, sending messages is a very efficient and effective way of dispersing information among huge numbers of parties.
2. It is event driven, which means that when an event occurs–a car arrives at a dealer's lot, a passenger boards a plane, a factory ships a truckload of parts–that event is recorded and made available.
3. It uses a publish-and-subscribe approach, which means that the informationabout the event is "published" to an electronic address and any system, person, or device authorized to see that information can "subscribe" to that address's information feed, which is automatically updated whenever a new event occurs.
4. It uses common data formats, which means the data formats used in disparate systems are reduced to common denominators that can be understood by other systems and shared.
