In this final section, we look at putting together the service requesters and service providers to create new choreography services.
在这最终的章节里，我们将服务请求者与服务提供者放在一起来创建新的编排服务。
In the next installment, I will examine service Choreography and the various means you have to build services and application systems from other services.
下一部分，将要讨论服务编排以及为其他服务构建服务和应用程序的各种方法。
Service status info - Choreography scenarios normally involve calling more than one service.
服务状态信息——流程编排场景通常包含调用多个服务。
The elemental services, used by the service choreography layer and also by user interface applications, are implemented by service applications.
基本服务(由服务编排层使用，也由用户界面应用程序使用)通过服务应用程序实现。
It will also be useful for dynamic selection of services at runtime, as I will discuss in a future paper on service Choreography.
正如我们将在关于服务编排的文章中所讨论的，UDDI在运行时对服务的UDDI动态选择方面很有用的。
MQ Workflow provides support for more mature but more proprietary service Choreography technology with either web services or proprietary interfaces.
MQWorkflow提供了对更成熟但更专有的服务编排技术的支持，该技术既有Web服务接口也有专有接口。
A business process is created by the composition and choreography of business services provided by service components.
业务流程是通过组合和编排服务组件所提供的业务服务创建而成的。
You can capture a change in business processes by changing the service choreography of composite services.
通过更改组合服务的服务编排，您可以捕获业务流程中的更改。
The sequencing, selection, and execution of operations is termed service or process choreography.
操作的排序、选择和执行称为服务或流程编排。
Hence, there are several levels of service aggregation or choreography to consider, which might well be suited to more than one implementation technology.
因此，需要考虑一些不同等级的服务聚集或编排，它可能适合不止一种实现技术。
Business processes - Executes BPEL business processes for service choreography.
业务流程——为服务编排执行BPEL业务流程。
The choreography is effectively a new service whose logic is completely provided by "gluing" together existing services.
该编排是一个有效的新服务，其逻辑完全是由“粘接”在一起的现有服务提供的。
The developed services are wired together through a process choreography engine, which is instrumental in providing the wiring mechanism of the business processes through the service interfaces.
已开发的服务将通过流程编排引擎连接到一起，该引擎可以帮助提供通过服务接口连接业务流程的机制。
In the SOA paradigm, business process choreography, maintained externally to the services, determines the sequence and timing of execution of the service invocations.
在soa范式中，在服务外面维护的业务流程编排决定了执行服务调用的顺序和时间。
Service choreography enables multiple services to be run sequentially in a coordinated fashion that implements a business process.
服务编排使得多个服务能够以一种同等的业务流程实现方式顺序运行。
These components include Business Service Directory, Business Service Choreography, and ESB Gateways.
这些组件包括业务服务目录、业务服务编排和ESB网关。
While Business Service Directory provides information about existing services, the Business Service Choreography component allows composing new services out of existing lower level services.
在业务服务目录提供关于现有服务的信息的同时，业务服务编排组件允许通过现有的低级服务组成新的服务。
This pattern consists of the implementation of a dedicated Service Choreography component.
这种模式由专用服务编排组件的实现组成。
Higher level SOA concepts, for example service choreography, directory, transformations, and so forth.
高级SOA概念，例如服务编排、目录、转换等等。
Service choreography can be used to create a coarse-grained interface that runs a business process consisting of fine-grained operations.
服务编排可以用来创建运行由细粒度操作组成的业务流程的粗粒度接口。
If we are to realize the SOA vision, then we must simplify the task of creating and modifying processes — that is, the task of service choreography.
如果要实现soa远景，则必须简化创建和修改流程的任务——即，服务编排任务。
It should be clear that the quality of service design can have a significant impact on the ease of choreography.
应当清楚，服务设计的质量对编排简化有很大的影响。
Being extended with the Service Choreography component allows the domain to compose higher level business functions that get consumed by the ESB.
通过服务编排组件进行扩展，使域可以组成ESB可消费的更高级别的业务功能。
A change in the choreography facilitates more easily than a change in the implementation of an elemental service.
编排中的更改比基本服务实现中的更改更简单。
To demonstrate how to use the simplified mediations, we show you how to create a new web service from a choreography of existing services.
为了演示如何使用简化的中介，我们将向您展示如何从现有服务的编排创建一个新的Web服务。
Rather, each web service involved in the choreography knows exactly when to execute its operations and whom to interact with.
相反，每个Web服务中所涉及的动作都确切地知道应该什么时候执行其业务和跟谁进行交互。
It performs mediation, message transformation, routing, process choreography, and provides quality of service (security, reliable message delivery, and transaction management).
其执行调解、消息转换、路由、流程编排并提供服务质量(安全、可靠的消息传递和交易记录管理)。
WSCI allows declaring exceptional behavior that is exhibited by a web service at a given point in choreography.
WSCI允许声明异常行为，由Web服务在编排好的点显示出来。
Figure 5 shows the business integration perspective of WebSphere integration Developer, which is used to refine and implement the business process using service choreography.
图5显示了WebSphereintegrationDeveloper的business integration透视图，它被用来通过服务编排来细化和实现业务流程。
In the service choreography layer, composite services are defined by means of a choreography language, such as BPEL (Business Process Execution language).
在服务编排层，组合服务是通过编排语言(例如业务流程执行语言(Business Process ExecutionLanguage,BPEL))定义的。
