The next steps involve computing from the different models described above - Use Case, Class model and Interaction diagram showing the flow of messages.
在分析阶段，我们的用例实现只包括分析类及分析对象，它们能组装成不同的UML图如类图和交互图。

另外，你可以从用例中产生序列图，协作图和类图。
In addition, you can produce sequence diagrams, collaboration diagrams, and class diagrams from use cases.
它也包括了可选择输入的一些其他工作产品，像用例实现，分析类，术语表等等。

Imagine if there were dozen of classes in each case — which one would be the most readable?
两个特殊的原型类被使用：业务角色和业务用例。
Two special stereotyped classes were used: business actors and business use cases.
从用例和类表出发，我们从类里选择需要交互的对象，然后构造一张序列图表示这种交互。
Starting with our use case and list of classes, we choose objects from those classes to interact, and we construct a SQD to show that interaction.
在面向对象的编程用例中，这些模型清楚地展示了连接到用例地类和方法。
In the case of object-oriented programming, these models clearly lay out the classes and methods linked to a use case.
这个用例控制类表示的是一个尚未进一步定义的类，它的职责是从用户那里接收事件和消息。
This Use Case Controller class represents a generic placeholder to receive events and messages from the human actor.
让我们用一个普通样例类(如清单3所示)来建模用户。
Let's take a sample trivial class for modeling users, as shown in Listing 3.
例子是用例、用例模型、业务规则、类、类图、序列图、数据模型和补充规约。
Examples are use cases, use case models, business rules, classes, class diagrams, sequence diagrams, the data model, and supplementary specifications.
用例既不是类规范，也不是数据规范。
A use case is neither a class specification nor a data specification.
根据RUP过程，这一步的目的是找出分析类的候选范围，这些类合作起来，可以完成用例的所有行为。
According to RUP, the purpose of this step is to identify a candidate set of analysis classes which will be capable of performing the behavior described in our use cases.
这些是包含用例扩展功能集合的类。
These are the classes that contain the extended set of functions for the use case.
但是迄今为止，我们还没有任何对象和类，因此我们需要从用例中去发现这些对象和类。
But so far we don't have any classes or objects yet, so we have to discover the classes that we will need to carry out the process in our use cases.
那就是单元测试：一系列记录类所做工作的用例代码，提供输出控制。
That's what these unit tests are: a set of coded use cases that document what a class does, given a controlled set of inputs.
找出用例中的执行流程、事件的各个类。
To identify the classes that perform the various flows of events in a use case.
