messaging system

基本解释

Some data, such as information from transactions, or some other messaging system, may already be in event format.
有些数据（比如来自事务或其他消息传送系统的信息）可能已经使用了事件格式。
When the two destinations are in the same messaging system, the receive and send can be done in a simple transaction because they involve a single transactional resource.
当两个目的地在同一个消息传递系统中时，接收和发送可以在一个简单事务中进行，这是因为它们只涉及单一的事务资源。
The JMS client can optionally control this transaction explicitly, such as to coordinate receiving a message from one queue with sending a message on another queue in the same messaging system.
JMS 客户端可以任意的显式控制该事务，比如在同一个消息传递系统中，协同处理从一个队列接收消息和向另一个队列发送消息。

The messaging system is not like traditional e-mail, according to fellow blogger Oliver Chiang.
