考虑到本文的目的，显示在SOAP消息中的任何数据类型编码是多么容易就已足够了，您可以用XML模式逻辑地描述该消息。
For the purposes of this article, it is sufficient to show how easy it is to encode any data type in a SOAP message that you can logically describe in an XML schema.
示例包括在逻辑消息树中创建具有正确数据类型的对象，以及根据模型验证xML。
Examples are creating objects in the logical message tree with the correct data type, and validating XML against the model.
但是大多数时候，需要将业务逻辑应用到数据中，这要求将数据提取为合适的数据类型。
But most of the time, you want to apply business logic to the data, which requires that the data be extracted to an appropriate data type.
对于这个场景，可以直接从逻辑模型中导出基本数据类型，作为XML开发的起点。
For this scenario, it can be useful to export the base data types directly from the logical model as a starting point for XML development.
这种简单的映射常常很好用，但是在某些时候，由于数据类型、格式或某个应用程序逻辑的不同，您不希望直接进行数据交换。
Quite often, this form of simple mapping works fine, but sometimes, because of differences in data types or formatting or the needs of some application logic, you don't want direct data exchange.
危机对更加复杂的设计建模，除了逻辑型，字符串型，整数型，用户自定义的数据类型，您可以对更加复杂的问题建模。
To model more complex designs, you can type tags by stereotypes and meta-classes, in addition to Boolean, string, integer, user-defined data type, and terms.
逻辑数据模型中的属性被指定一个物理数据类型。
Attributes in the logical data model are assigned a physical data type.
为了高效地管理XML数据，像传统的SQL数据类型一样，DB 2在内部使用XML数据模型作为逻辑数据模型，同时也作为物理存储的基本单元。
To efficiently manage XML data, like traditional SQL data types, DB2 USES the XML data model internally, as the logical data model and as the fundamental unit of physical storage.
随着上述两种端口类型之间的一些引用的增加，到目前为止，WSDL文档已经从具体和实际形式(数据类型)转变为抽象和逻辑形式(消息和端口类型)。
The WSDL document so far has moved from the concrete and physical (data typing) to the abstract and logical (messages and port types), with some reference between the two.
研究了系统的程序指令集、逻辑堆栈和I/O存储器数据类型，实验表明系统具有良好的实时性和可靠性。
Program instruction set, logic stack and data type of I/O memory which are tied up with tasks in the soft-PLC system are analyzed and studied.
抽象数据类型简称adt，是一种对数据的逻辑抽象，对他的操作方法无需关注具体的实现。
ADT, is a logical description of how we view the data and the operations that are allowed without regard to how they will be implemented.
