消息交换模式：数据服务可以通过四种主要的消息交换模式被访问：请求-应答（严格SLA）、请求-应答（宽松SLA ），即发即弃和发布-订阅。
Message exchange pattern: data services could be accessed via the four primary message exchange patterns - request/reply (tight SLA), request/reply (relaxed SLA), fire/forget, and publish/subscribe.
访问和修改数据的应用程序越多，对模式所提供的结构和指导的需求越迫切。
