那么如何从业务流程标识用例呢？
因此，业务流程的不同视图就是步骤的序列，其中每个步骤都是具有希望的输出和行为的用例。
Hence, a different view of a business process is that of a sequence of steps with each step being a use case with a desirable output and behavior.
如对业务流程中活动所做的处理一样，在业务模型中，也可以将业务用例确定为的核心的、可选的，或选择性的。
As was done with activities in the business Process, business Use Cases can also be identified as being kernel, optional, or alternative within the business model.

你可以使用这种联系，以在业务流程和它所实现的业务用例之间进行切换。
You can use this link to navigate between the business process and the business use case that it realizes.
设计具有一个重要的特征，它应该追溯到更高抽象级别的元素(例如，业务流程或者用例)，包括需求。
A key characteristic of the design is that it should trace back to elements at higher levels of abstractions (for example, business processes or use cases), including requirements.
为每个业务用例突出其业务用例实现，并且定义如何连接返回到业务流程图的活动。
Highlight the Business Use Case Realizations for each Business Use Case, and define how they link back to the Business Process Map activities.
在自顶向下方法中，将首先从高级业务用例或组织中存在的业务流程流开始。

第二个步骤中的一部分是具体的业务流程活动及其相应的已确定的业务用例之间可追溯的形式化定义。
Part of this second step is the formal definition of the trace between a specific business process activity and the corresponding identified business use case.
根据白皮书，许多现有的业务架构方法都关注在IT解决方案交付的必备的前提之上，也就是业务流程和业务用例。
According to the whitepaper, many of the current business architecture approaches are focusing on the prerequisite to IT-based business solution delivery - business processes and business USES cases.
由于用例可以作为业务流程中的步骤进行标识，因此每个用例都有其存在的意义。
Since the use cases might be identified as steps within a business process, every single use case has a purpose for existence.
另一种思考业务用例的方式是，它记录了特定的业务流程。
Another way to think of a business use case is that it documents a particular business workflow.
自顶向下方法旨在分解业务元素（主要是业务流程和用例），然后将它们细化为适合服务的粒度。
The top-down approach is about decomposing business elements (mainly business processes and use cases) and refining them into a granularity that makes sense for services.
组成给定业务流程模型的活动或流程步骤可以作为用例建模的基础进行分析。
The activities or process steps that make up a given business process model can be analyzed to form the basis of use case modeling.
业务流程中的流程步骤之间的过渡被映射为用例之间的依赖关系。
Transition between process steps within a business process is mapped as dependencies between use cases.
没有未标识的用例，而且在此工作结束时，业务流程组合中的每个步骤都有指定的用例名称和执行的主要步骤。
No use case is left unidentified and at the end of this work effort and every single step in the business process portfolio has an assigned use case name and major steps of execution.
用例应该说明系统如何支持域和业务流程模型中的业务流程。
The use cases should tell the stories of how the system supports the business processes in the domain and business process models.
OOAD中的典型起点是用例模型，但SOAD中的起点是业务流程建模。
The typical starting point in OOAD is use-case models, but the starting point in SOAD is business-process modeling.
图16展示了用业务流程模式以及电子商务模式实现的用例。
Figure 16 shows the use cases implemented by business Process pattern and the patterns for e-business patterns that implement those use cases.
这些用例包括 其下层的可重用业务流程（长时间运行或短时间运行）。
These use cases include reusable business processes (long or short running) in the layers below.
业务流程管理(Business Process Management,BPM)是基于流程的方法，通常以业务流程和用例的自顶向下建模为基础。
Business process management (BPM) is a process-based approach, usually arising from a top-down modeling of business processes and use cases.
在Rational Software Architect中使用业务用例uml关系图集成的需求和业务流程。
Requirements and business process are integrated in Rational Software Architect with the business use case UML diagram.
流程模型对实现端到端业务流程的任务序列(既包括本身就是原子任务的任务，又包括由用例表示的任务)进行标识。
The process model identifies a sequence of tasks (either atomic in nature or represented by use cases) that realize an end-to-end business process.
流程模型对实现端到端业务流程的任务序列(既包括本身就是原子任务的任务，又包括由用例表示的任务)进行标识。
The process model identifies a sequence of tasks (either atomic in nature or represented by use cases) that realize an end-to-end business process.
