Another subject of frequent debate is whether a service is synchronous or asynchronous, and what role the used communication protocol plays compared to the programming model.
另一个经常讨论的主题是，服务是同步的还是异步的，与编程模型相比，使用的通信协议充当什么角色。
As described above, the SCA programming model supports three types of asynchronous invocation patterns.
如上所述，SCA编程模型支持三种类型的异步调用模式。
Components in this model need means to coordinate between messages, deal with complex failure scenarios, and effectively deal with asynchronous programming.
组件在这个模型中需要在消息之间进行协调，处理复杂的失败场景并且高效的处理异步编程。
This form of asynchronous, message-oriented programming model has been around for quite some time and is, of course, broadly implemented in enterprise application development.
这种形式的面向消息的异步编程模型很早就提出了，当然在企业应用程序开发中广泛实现。
