我们将构建基于SOA的WCF服务。在最近的一次会议，客户介绍新的系统环境。他用了对外事务。由于时间的限制，我无法得到它澄清。然后，我在做一些互联网搜索。然而，它使我不同的主题。

所以，我的问题是 - 什么是对外事务中的服务意识的背景下？你能举个例子吗？

WCF, DataPower的集成 - 安全的结合必要的

解决方案

为了你的项目，你一定要做的@Marc建议和跟进客户。

但是，一般来说，对于异步或分批类型的通信

在入站消息 - 该消息的流量进入你的系统 在出站消息 - 消息流流出你的系统。

（显然呼入/呼出的方向取决于视系统或ESB / EAI枢纽点 - 系统架构师在界面的另一侧可以看到事物的其他方式）

字的交易可能意味着很多东西：

在ACID事务（单相，如SQL BEGIN TRAN，或者两相如XA / DTC） 补偿/长期运行的事务（通常在ESB或EAI或BPEL引擎的上下文中） 在系统之间流动的数据中包含的金融交易（即业务领域范围内，无关XA / DTC / SQL交易的话）

We are going to build WCF services based on SOA. During a meeting recently, client explained the new system environment. He used the word "outbound transaction". Due to time limitations, I could not get it clarified. Then I made some search in internet. However it leads me to different topics.

So, my question is - what is "Outbound Transaction" in the context of "service orientation"? Can you give an example?

解决方案

For the sake of your project, make sure you do as @Marc suggests and follow up with the client.

But, in general terms, for asynchronous or batch type communication

Inbound message - the flow of the message comes into YOUR system Outbound message - the flow of the message flows out of YOUR system.

(obviously the direction of inbound / outbound depends on the point of view of the system or esb / eai hub - system architects on the other side of the interface will see things the other way around)

The word transaction might mean many things:

ACID Transactions (Single phase, e.g. SQL BEGIN TRAN, or Two Phase e.g. XA/DTC) Compensated / Long running transactions (usually in context of a ESB or EAI or BPEL engine) The data flowing between systems contains Financial transactions (i.e. business domain context, nothing to do with XA / DTC / SQL transactions at all)
