Publish/Subscribe Pattern

The Publish-Subscribe Pattern is a messaging system where information is shared without direct connections between the sender and the receiver. In this model, a "publisher" creates messages and sends them to a designated channel, while "subscribers" express interest in specific topics and receive messages from those channels. This allows multiple subscribers to get updates simultaneously, without the publisher knowing who they are. It’s like a radio station (publisher) broadcasting music (messages) to listeners (subscribers) who tune in to specific frequencies (topics) of their choice, ensuring efficient communication and organization of information.
