类图从用例图 [英] Class diagram from use case diagram

问题描述

我有以下用例图

从这个图中创建类的最好方法是什么？

尝试创建两个主类（ UserManager 和 ContentManager ），但整个类结构看起来错误和不合逻辑。

任何人都可以提供一个简单的例子来帮助我？

下面我粘贴了我的类图。

解决方案

A 类事物从问题域，不是任意桶的代码。例如，您应该有类注释，文章，公告和 Advertisement 。您应该在相关类之间具有关联，每个关联具有命名属性和多重性。结果应类似于此< a>。你最终会给每个班级的责任。

以 Manager 结尾的类名表示您正在进行它错了。

I have the following use case diagram

What is the best way to create a class from this diagram?

I've tried creating two main classes (UserManager and ContentManager) but the whole class structure looks wrong and illogical.

Can anyone provide a simple example to help me?

[Edit] Below I've pasted my class diagram. What would you change or what do you think about it?

解决方案

A Class represents a set of things from the problem domain, not an arbitrary bucket of code. For example, you should have classes like Comment, Article, Announcement, and Advertisement. You should have associations between pairs of related classes, each association having named properties and multiplicities. The result should look like this. You will eventually give each of those classes responsibilities. That is how object oriented analysis and design works.

Class names ending in the word Manager indicate you're doing it wrong.
