解析：[参考译文] 服务构件架构(Service Component Architecture)致力于为使用广泛的编程语言来构造服务构件提供一种编程模型，并且也为把这些服务构件组装为一个业务上的解决方案提供了一种模型，这种组装的活动正是采用面向服务的架构(service-oriented architecture)来搭建应用系统的核心的。
服务数据对象(Service Data Objects)致力于为应用系统中处理数据(data)提供统一的方式，而不论数据的来源、格式(format)是什么样的。SDO提供了一种对数据库和对服务来说统一的数据处理方式，它也提供了相应的机制，用来实现当数据同其来源分离(detached)时的处理。
