Like UML models that are abstractions of the application architecture, data models represent the abstraction of the information model.
就像uml模型是应用程序架构的抽象一样，数据模型表示信息模型的抽象。
During this process, the data modeler often makes extensions or changes to this model, which can then be transformed back into a UML model.

Activities in UML are used to model flows of various kinds: signal or data flows, as well as algorithmic or procedural flows.
在UML中，活动被用来对不同种类的流程建模：信号流或数据流，也有算法流或过程流。
The UML profile and data type model
UML概要文件和数据类型模型
The UML model and the XML Schema are both data models, though they use different languages and usually offer different levels of detail.
尽管使用不同的语言，提供的详略程度一般也不相同，但是UML模型和XMLSchema都是数据模型。
The XPath language is used to express queries for both the rows and columns of each UML model data set.
XPath语言是用来快速查询每个UML模型数据集的行和直列的。
The transformation relies on a mapping from the UML metamodel -- the data model into which UML models are saved -- to an XML Schema.
转换依赖于UML元模型（保存 UML模型的数据模型）到XMLSchema 的映射。
For example, you can create a data set of all of the UML Actors in the model using //Actor, even though in the XML document for the model there is no such node as "Actor."
例如，您可以在模型使用//Actor中创建所有UMLActors的数据集，即使是在)没有 “Actor”这样节点的模型XML文献中。
RDA provides transformation from Unified Modeling Language (UML) to the Logical Data Model and vice versa.
RDA能够在统一建模语言(uml)与逻辑数据模型之间进行相互转换。
UML lacks, however, the sufficient management of behavior code in database, makes against tracing and extension, when using UML to design data model.
然而使用UML进行数据模型设计时，对数据库中的行为代码却缺乏有效的管理，不利于对其跟踪、扩展。
