sdo

As mentioned, one goal of SDO is that it is possible to represent the sort of structured data usually stored as XML.

前面已经提到，SDO的目标之一就是可表示通常存储为XML的结构化数据。

Let's begin by pulling apart the term Service Data Object (SDO) to see how the name came about.

让我们首先来剖析一下服务数据对象（SDO）这个术语，看看其来源。

One of the responsibilities of the SDO DataGraph is to keep track of any changes within the object graph.

SDODataGraph的职责之一是跟踪对象图形中的任何更改。

Since the blog is cumulative and we want to read in a blog like the one above, add an item, and write it out, we use the SDO XML DAS.

由于blog为累积式的，我们希望读入一个与上例类似的blog、添加项目并将其写出，因此使用SDOXMLDAS。

Now all that you need to do is create a database connection, and you will be ready to create SDOs to access the database.

现在您所需要做的就是创建一个数据库连接，并且您将准备好创建SDO来访问数据库。

For those familiar with JDBC concepts and the java. sql. ResultSet interface, the SDO dynamic API mode will be easy to understand.

对于熟悉JDBC概念和java.sql.ResultSet接口的读者来说，SDO的动态API模式是很容易理解的。

While JAXB is only focused on a Java-to-XML binding, XML isn't the only kind of data being bound to SDO.

JAXB仅关注Java到XML的绑定，而绑定到SDO的不仅仅是XML数据。

At the heart of every SDO instance is a model that defines the permitted structure of a data object.

在每个SDO实例的中心都有一个模式，用于定义所允许的数据对象结构。

The method getString( "value" ) is part of the SDO dynamic interface and needs a bit of an explanation.

方法getString（“value”）是SDO动态接口的组成部分，需要对其进行一点说明。

SDO is not just a specification. You can already find tools that leverage SDO technology to access a heterogeneous EIS.

SDO不仅仅是一个规范，您可能已经发现了有一些工具利用了SDO技术来访问异构的EIS。

Highlighted different techniques that are commonly used for manipulating SDO instances when building an XML-based SOA application.

中，突出了在构建基于XML的SOA应用程序时用于处理SDO实例的不同技术。

Additionally, an SDO object can be used to carry information between the presentation layer and the business layer.

此外SDO对象可以在表示层和业务层间传递信息。

It allows configuration of any XML binding mechanism like JAXB, SDO, Castor etc. by implementing the standard framework interface.

通过实现标准的框架接口，它支持任何XML绑定机制，如JAXB、SDO、Castor等。

SDO and EII technologies can be used together to provide Java architects with a single, object-based API to a wide variety of data sources.

SDO和EII技术为Java体系结构提供了对各种数据源的单一的、基于对象的API。

The SDO architecture provides a set of core components, which are supposed to be augmented by SDO-capable implementations and frameworks.

SDO体系结构提供了一组核心组件，这些组件可以由支持SDO的实现和框架进行扩充。

SDO will change our understanding of the sun and its processes, which affect our lives and society.

太阳动力学观测卫星将改变人们对太阳及其进化过程的认识，这些认识对我们生活和社会有深远影响。

It would be nice if SDO implementation were to do this test on our behalf.

如果SDO实现能够代替我们执行此项测试则较为理想。

An SDO instance thus can only be contained by one container at a time.

因此一个SDO实例在同一时刻仅能被一个容器所包含。

If you attempt to assign an SDO of a different SDO type (another author, perhaps) or a primitive, SDO would throw an exception.

若试图指派一个不同SDO类型的SDO（比如说，另外一名作者）或原生数据类型，SDO将抛出异常。

Using SDO, an application takes advantage of these proven design strategies. It fosters layering and loose coupling.

如果使用了SDO，应用程序就可以从这些经过了验证的设计策略中受益，从而可以推动分层技术和松耦合的发展。
