In some sense, the use-case model lets us make the link between the high-level business function and the low-level code that implement these functions.
在某种意义上，用例模型让我们链接了高层业务功能和实现这些功能的低层代码。
This allows us to evaluate the completeness of the use-case model from a business perspective, as each system use case must support one or more business use cases.

The Piggy Bank sample is divided into three UML models that each describe a different aspect of the system: the use-case model, analysis model, and design model.
PiggyBank范例被分成三个UML模型，每个模型都描述了系统的不同方面：用例模型，分析模型和设计模型。
Because a use-case model is defined from a business analyst's view, it provides a level of abstraction that's a useful communication tool for project stakeholders.
因为用例模型是从业务分析师的视角定义的，所以它提供了一种层次的抽象，对项目相关者来说是有用的沟通工具。
The RUP documentation shows the evolution from business use-case model to business object model and system use-case model; we found this to be quite accurate and helpful.
RUP的文档显示了从业务用例模型到业务对象模型和系统用例模型的演进；我们发现这是非常正确和有帮助的。
Your use-case model is composed of the use-case diagram(s) plus any supporting documentation: i.e., use-case specifications and actor descriptions (if you choose to document them).
您的用例模型由用例图，加上支持文档组成：也就是，用例说明及角色描述（如果您选择将它们编制为文件）。
Use-Case Model (about 80% complete, depending on iteration goals).
用例模型(大约80%完成，取决于迭代目标)。
The Use-Case Model in turn is the source for the subsequent Use-Case Specifications.
而用例模型又是随后的用例规格说明 的来源。
For example, if a Use-Case Model is referenced by the contents of multiple projects, it should not reside in any of those referencing projects.
举例来说，如果一个用例模型被多个项目的内容所引用，那么它就不应当存在于任何一个引用项目中。
The resulting System Use Case model is shown in Figure 13, and includes all the use cases identified.
结果产生的系统用例模型如图13所示，并且包括已确定的所有用例。
After you extend the basic DITA task topic, you can use this new schema to build use cases; from these use cases, you can build a use case model that is flexible and easy to maintain.
扩展基本DITA任务主题之后，您可以使用这个新模式来构建用例；利用这些用例，您可以构建一个灵活且易于维护的用例模型。
Testers can more efficiently plan and execute testing when employing the use case model.
当利用这些用例模式时，测试人员可用更有效地设计和执行测试。
The completed use case model should allow all the stakeholders to see how the system supports their roles.
完成后的用例模型应该允许所有的利益相关者看见系统是如何支持他们的角色的。
With a level of analysis performed at this point, a formal use case model can be created and documented.
此时通过执行某种级别的分析，可以创建并记录正式的用例模型。
When an organization is complex and trying to automate significant functions, a business use case model can be invaluable.
当一个复杂的开发组织试图自动处理重要的功能时，业务用例模型是非常宝贵的。
In previous columns, we have established a use case model in which actors represent external entities that interact with our system.
在前面的专栏文章中，我们构建了一个用例模型，参与者在其中表示与系统交互的外部实体。
The session bean's behavior follows the collected behavior of the actor across the use case model.
会话bean的行为与参与者在用例模型内汇集起来的行为一致。
A common problem is that the use case model explodes in size very quickly, especially when you are working on the abstraction level of business requirements.
一个通常的问题是用例模型爆炸式快速增长，特别当你正在业务需求的抽象层工作的时候。
