SCA divides the steps of building of a Service Oriented Application into two major parts.
SCA将构建面向服务的应用程序的步骤划分为两个主要部分。
A new service-oriented application exposes business behavior as a service and also reuses business logic, which is exposed as a service.
面向服务的新应用程序将业务行为作为一项服务予以公开，它还会重用业务逻辑，业务逻辑也是作为服务公开的。
A true service-oriented application can aggregate different types of specifications together, dynamically generated from Web services.
一个真正的面向服务的应用程序可以将不同类型的规范聚合在一起，由Web服务动态地生成。
A scenario for the involvement of a human in a service-oriented application is a process that requires a decision from a person to approve an order before proceeding, as shown in Figure 13.
面向服务的应用程序中涉及到人的场景之一是这样的流程：该流程在继续之前，需要某人做出决策来批准订单，如图13所示。
Additionally, the OSGi platform also provides a service-oriented application model, which allows OSGi-based applications to be built from service-oriented principles in addition to being modular.
另外，OSGi平台还提供面向服务的应用模型，除了模块化之外，它还允许基于OSGi的应用按照面向服务原则来构建。
In order to show a glimpse of how such a service-oriented Architecture may be realized, we implement a calendar feed as a mere shadow of a much larger service-oriented application through LAWS.
为了简要介绍如何实现这种面向服务的体系结构，我们实现了一个日历feed，以此作为通过LAWS实现的大型的面向服务的应用程序的一个缩影。
