例子：声明映射领域实体。
会引入哪些领域实体？
创建领域实体文件声明扩展topicref的元素。
Create a domain entities file to declare the elements that extend the topicref element.
用Repository模式实现领域实体访问。
创建外壳DTD组装基本的映射模块、领域实体文件和定义模块。
Create a shell DTD that assembles the base map module and the domain entities file and definition module.

A data Mapper pattern is used to map domain entities to the database schema.
我们利用条件随机场模型抽取领域实体对象，并将其应用于比较句识别和比较关系抽取中，取得了良好的实验效果。
We use CRF model to extract domain entities which are applied to identify comparative sentences and mine comparative relation with good results.
将企业的各个业务领域链接在一起的核心数据实体跨所有业务线保持一致和可信。
That the core data entities linking together the business domains of an enterprise are consistent and trusted across all lines of business.
每一个应用系统的核心是描述这个系统的基础模型 --领域模型、类模型、逻辑模型、实体模型等等。
The heart of every application is the base model that describes it -- a domain model, class model, logical model, entity model, or the like.
业务实体和领域模型。
它同时还包含了表示特定业务领域对象的业务实体。
It also includes business entities that represent objects specific to a business domain.
功能特性还有助于挑战软件不可见性，因为作为跟踪领域中立组件中的系统实体间交互结果的新功能特性可能被揭示。
Features also help to combat software invisibility, because new features may be uncovered as a result of tracing interactions between the system entities in the domain neutral component.
领域模型还帮助标识这些实体的属性和重要方法。
The domain model also helps identify the attributes and important methods of those entities.
如果多个不同的业务领域间需要通信，那你就需要明确相互通信的关键实体是什么。
If you have diverse areas of the business trying to communicate then you need clarity on the key entities within the business that you are communicating around.
有些形式的规则在模型中的业务类型定义中是隐式的，它们出现在被建模领域的业务类型的UML和实体关系(ER)模型中。
Certain forms of rules are implicit in the definition of the business types in the model, and manifest in UML and entity relationship (er) models of the business types of the modeled domain.
这个维可以分为两个级别：领域(数据元素)级和实体级。
This dimension can be considered at two levels: the domain (data element) level and the entity level.
实体级代表一个单独的对象，比如人、位置或产品，它由不同的领域或属性组成。
The entity level represents a distinct object such as a person, a location, or a product comprised of distinguishing domains or attributes.
本教程还将简要讨论可用于将所有此类实体引入接触点领域中的技术。
The tutorial also briefly discusses techniques by which all such entities can be brought into the touchpoint arena.
产品领域主要关注产品实体和特定产品的特征(如属性、规则、条款和条件、定价、风险等)。
The product domain primarily focuses on the product entity and the characteristics of the specific product (like attributes, rules, terms and conditions, pricing, risk, and so on).
后面将会提到，这种机制的技术基础是DDD，可以用一种优雅的方式将实体提升为富领域对象。
The mechanism for that, as will be explained further below, lays the technical foundation for DDD and allows entities to be promoted to rich domain objects in an elegant way.
一个实体若想成为富领域对象不仅要包含状态，还得能调用业务服务。
For an entity to be considered a rich domain object it should not only contain state but also be able to call business services.
根据组织在实现相关领域或操作实体的已知目标方面的成功程度度量成熟度级别。
Maturity levels are measured by the amount of success the organization has in achievement of identified goals for the areas or operational entities of the domain in question.
要想使用领域设计方法，你就需要为实体类定义和构建资源库来实现领域对象的持久化。
Using a domain driven design approach you will need to define and build repositories for the entities that make up your domain.
因为数据库表本身没有行为，开发人员常常把领域模型实体的行为放在服务或视图层中。
Because database tables by themselves do not have behavior, it's tempting to put the behavior of domain-model entities in services or the view layer.
领域模型展示了主要商业实体，它们的功能责任，以及实体之间的关系。
The domain model typically shows the major business entities, their functional responsibilities, and the relationships among the entities.
不过就目前而言，最有希望的领域或许还是实体基础设施这一方面。
Yet the most promising field for now may be physical infrastructures.
这个应用使用领域模型表示这个系统中的实体，并使用ORM框架把领域模型映射到数据库上。
It has a domain model representing the major entities within the system, and USES an ORM framework to map the domain model to the database.
如领域专门化一文(请参阅参考资料)中所述，内容模型中的实体使用支持领域专门化。
The use of entities in the content models support domain specialization, as described in the domain specialization article (see Resources).
与主题领域相同，“how - to”领域也使用外壳DTD把基本的映射模块和实体文件、定义模块组装在一起。
As with topic domains, a shell DTD assembles the base map module with the entities file and definition module for the how-to domain.
因为数据库不支持与实体相关联的行为，领域模型最终只具有简单的变量以及相关的getter和setter方法。
Because databases do not support behavior associated with entities, the domain model ended up having simple variables with getter and setter methods for them.
