The DEBA framework is an implementation of this unique capability.
DEBA框架是这种能力的唯一实现。
DEBA is characterized by distributed active components waiting for events.
DEBA的特点是等待事件的分布式活动组件。
So the DEBA architecture is naturally complementary to Grid computing.
所以，DEBA架构本质上是网格计算(Grid computing)的补充。
There is a great deal of flexibility in the DEBA framework to handle exceptions.
在DEBA框架中对异常的处理具有良好的灵活性。
It is the Observer pattern on top of the base web services infrastructure that gives DEBA its callback capability.
在基本Web服务结构之上采用观察者模式，就为DEBA带来了回调能力。

There are two layers of proxies in the deba framework: SOAP proxies and the framework's own, all packaged in deba.core.
在deba框架中有两层代理：SOAP代理和框架自身的代理，都打包在deba . core中。
The capabilities of the DEBA event model are quite different from those that the limited WSDL Notification operation can provide.
DEBA事件模型提供了一种大有不同的功能，有别于WSDL通知操作所能提供的功能，WSDL通知操作带有自身的局限性。
DEBA for web services benefits from the decoupled nature of web services and the asynchronous nature of the Observer pattern.
将DEBA应用到Web服务中可以获得两方面的好处，包括Web服务的解藕特性和观察者模式的异步特性。
It can also serve as a basis from which you can implement your own DEBA framework applications. The classes in the example application are.
它也可以作为你实现自己的DEBA框架应用程序的基础。
Using the DEBA framework, developers extend AbstractWebObservable to implement their own observable web services on top of the framework.
使用DEBA框架，开发人员扩展了AbstractWebObservable，在框架的顶层实现了它们自己的被观察Web服务。
In fact, he had arrived in Nowa Deba, southern Poland, having picked the wrong bus, another from the same line having left Athens for Italy.
事实上，他到了波兰南部的诺瓦·德巴，他从雅典出发时搞错公车，错过另一辆开往义大利的同线公车。
The DEBA architecture ties in very nicely with grid architectures (see Resources) in that each component can join and leave the grid at will.
DEBA架构和网格(Grid)架构结合得非常好，其中的每个组件都可以随意的加入或者离开网格(请参阅参考资料)。
Systems built on DEBA can be thought of as always moving towards equilibrium, with participants joining and leaving at will, based on application logic.
建立在DEBA之上的系统总是试图达到一种均衡，参与者可以随意的加入和离开，这些都是建立在应用程序逻辑的基础之上。
DEBA is unique because it allows the inherently synchronous web services model to provide the foundation for such an entirely asynchronous architecture.
DEBA的独特之处在于它提供了一个改变，让本来同步的Web服务模型也能够提供完全异步的体系结构。
We've provided a default validation callout mechanism in the DEBA framework to limit exceptions caused by the lack of availability of the observable or observer.
在DEBA框架中提供了默认的验证调用机制，减少了观察目标和观察者的可用性问题所导致的异常。
A workflow model central node controls the nodes participating in a distributed state machine and two router models; the entire system is implemented with DEBA.
工作流模型的一个中央节点控制那些参与了分布式状态机和两个路由器模型的多个节点；整个系统是使用DEBA来实现的。
In this article, we've explained the DEBA framework and how you can use it to implement a variety of flexible distributed application architectures using web services.
本文种我们解释了DEBA架构，如何使用它来构建多种灵活的分布式Web服务应用程序。
Table 1 shows the correspondence between the Observer pattern, the standard web services model, and the Observer pattern's implementation in the DEBA framework classes.
表1中三个方面的对照，分别为观察者模式、标准Web服务模型，以及在DEBA框架类中观察者模型的实现。
Another design pattern that lends itself well to DEBA is the Visitor pattern, which externalizes an operation that will be performed on another object, a group of objects, or a structure of objects.
另外一种可用于DEBA架构的设计模式是Visitor(访问者)模式，将操作外部化，可以对其他对象、对象组或者对象结构执行这些操作。
