Service Broker Architecture
SQL Server 2005
Service Broker applications are made up of Service Broker database objects and one or more applications that use those objects. This section describes each of the objects used in a Service Broker application.
There are three types of Service Broker components:
-
Conversation components. The run-time structure of the conversation. Applications exchange messages as part of a conversation.
-
Service definition objects. These are design-time components that specify the basic design of the application. These components define the message types for the application, the conversation flow for the application, and the database storage for the application.
-
Routing and security components. These components define the infrastructure for exchanging messages outside of a SQL Server instance.

This section also presents short overview of building applications with Service Broker.
