 ## Topics
 
 In a previous exercise, we mentioned that a topic is a means by which a publisher classifies a message. The topic tells us what type of message we will receive if we subscribe to a specific topic. In essence, it is a string that is composed of one or more levels. Each level is separated by a forward slash (/) and the levels can be anything. This is commonly known as topic-level granularity. The granularity allows for more targeted and efficient information exchange. Instead of having a single topic for all updates on a business object in a complex system (/BusinessPartner), the system can have distinct topics for different types of updates on a business object (/BusinessPartner/Created, /BusinessPartner/Updated, /BusinessPartner/Deleted). There is no specific schema/specification on how you need to structure your topic string but you do find that patterns are established within a system. Let's get familiar with the structure of a topic by "dissecting" a real-world topic. Below we can see a topic on which an SAP S/4HANA Cloud system will publish a Business Partner message.

 As explained previously, we can subscribe to a topic directly and so far we've created a topic subscription. For us to receive messages, our subscriber needs to be online and connected to AEM. But what if we want to ensure that we receive all messages published, even if our subscriber is offline? This is where Queues come into play. Let's explore how we can create a queue to receive/accumulate messages in it and finally, we will subscribe to it.
