通过为分布式应用程序提供经过良好定义的接口和数据交换格式，架构的Web服务实现克服了这些挑战。
A Web Service implementation of the architecture overcomes these challenges by providing a well-defined interface and data exchange format for a distributed application.
提供了观察BusinessContractModel所需的工具，以及开发可以用于为不同的架构风格生成实现代码的服务实现模型所需的工具。
Provides the tools needed to view the Business Contract model and develop service realization models that can be used to generate implementation code for different architectural styles.
然而，基础架构支持在不影响服务的客户端的情况下由另一个服务实现替代原有的服务实现也是至关重要的。
However, it is also vital that the infrastructure supports the substitution of one service implementation by another with no effect to the clients of that service.
服务实现是由软件架构师和设计师来完成的。
Service realization is performed by the software architect and the designer.
架构师将确定哪些用例可以使用之前已有的应用程序或服务实现，而哪些用例需要进行构造或扩展。
The architect determines which use cases can be implemented by pre-existing applications or services and which use cases need to be constructed or extended.
本例中所要做的最后一件事就是将我们的方案与在第一篇文章中，第1部分：服务实现所设计的服务架构联系起来。
The last thing to do in this example is to tie our solution back to the service architecture that we designed in the first article, Part 1. Service identification.
此图强调中介(用于服务公开)和提供者创建都对服务实现有贡献，但是由于关注点隔离的要求，它们在架构上是分离的。
The figure emphasizes that mediation (for service exposure) and provider creation contribute to service realization, but they are architecturally distinct due to separation of concerns.
图11，摘自“第1部分：服务实现”，显示了处理购买订单的服务架构。
Figure 11, which is from Part 1. Service identification, shows the service architecture for processing purchase orders.
我理解的SOA作为一个面向服务的架构，它是对具体技术和业务实现不敏感的。
I understand SOA as a service-oriented architecture, which is agnostic to the technical or business implementation; I will follow the OASIS SO RM standard and OASIS SOAR a when talking about SOA.
在开发的时候，你可以将服务实现与托管服务的拓扑(系统架构师建模的部署拓扑)关联在一起。
At development time, you can associate a service implementation with the topology that hosts it (the deployment topology that the system architect models).
这种面向服务架构具有业务和技术两面，但技术是作为业务实现的一种形式出现。
This service-oriented architecture has business and technical aspects but technology appears as one of the forms of the business implementation.
