Can u explain about Pub-Sub Architecture, where do u implemented this?

1) Point-to-point Architecture

2) Point-to-Multiple Architecture

1) Point-to-point Architecture

In this architecture source system will publish the data and target system will receive the data.

2) Point-to-Multiple Architecture

In this Source system will publish the data to Broker, from broker multiple target systems will subscribe.

Publisher publishes a document broker then the subscriber receive the document from broker. You should make document as publishable at publisher side.

Subscriber should subscribe to that particular document by creating a trigger. The trigger monitors that document. If a subscribed document got published then trigger invokes a service which associates with trigger to handle the document.

This is the general architecture of PUBLISH- SUBSCRIBE model.
