ServiceBrokerExtSource
SQL Server 2005 Service Broker (SSB) is an asynchronous messaging technology built into SQL Server. With SSB, you essentially get the power of messaging technologies like Microsoft Message Queue (MSMQ) combined with the relational database capabilities of SQL Server, all controlled with Transact SQL statements(SQL Server 2005 Service Broker (SSB) is an a synchronous messaging technology built into S QL Server.
