19.3. Service Broker Elements

Service Broker employs a framework that uses messages as a unit of work. However, the handling and processing of these messages are defined by a variety of elements, including the conversation architecture, delivery contracts, queues, and services. In this section, you learn about the components that are used in a Service Broker solution.

19.3.1. Conversations

Service Broker uses conversations to define a persistent communication architecture that is reliable and asynchronous. The conversation architecture uses messages, dialogs, and conversation groups to control the flow of data in a Service Broker application.
