在UML类图中，什么是边界类，控件类和实体类？
我现在使用NetBeans作为我的选择，并且它具有用于UML建模的插件。在类图中，有称为 Boundary Class ， Control Class 和的模型元素实体类。但是，我找不到很好的定义，但确实找到了此网站
I'm now using NetBeans as my IDE-of-choice, and it has a plugin for UML modeling. In the class diagram, there are model elements known as Boundary Class, Control Class, and Entity Class. However, I can't find a good definition of them, but I did find this site on UML Class Diagrams.
通常与OOAD和业务建模一起使用或作为其一部分。 Neil的定义是正确的，但它与MVC基本相同，只是为业务而抽象。 好的摘要做得很好，因此我不会在这里复制它，因为它不是我的工作，更详细，但与Neil的要点一致。
Often used with/as a part of OOAD and business modeling. The definition by Neil is correct, but it is basically identical to MVC, but just abstracted for the business. The "Good summary" is well done so I will not copy it here as it is not my work, more detailed but inline with Neil's bullet points.
很好的摘要-概念：实体控制边界模式
