UML diagrams

 
UML 2.0 has 13 types of diagrams that can be categorized hierarchically as shown in the following Class diagram:
Hierarchy of UML 2.0 Diagrams, shown as a class diagram
Structure diagrams emphasize what things must be in the system being modeled:

Behavior diagrams emphasize what must happen in the system being modeled:

Interaction diagrams, a subset of behavior diagrams, emphasize the flow of control and data among the things in the system being modeled:

The Protocol State Machine is a sub-variant of the State Machine. It may be used to model network communication protocols.

UML does not restrict UML element types to a certain diagram type. In general, every UML element may appear on almost all types of diagrams. This flexibility has been partially restricted in UML 2.0.

In keeping with the tradition of engineering drawings, a comment or note explaining usage, constraint, or intent is always allowed in a UML diagram.

去年请搬家公司搬家的时候,我和同学的电脑各被搬运工拔了一条内存条。我还记得当时,因为看那几位工人为了帮我们搬东西而汗流浃背,我和同学基本上加入了他们的工作,帮他们一起搬。没成想他们居然有这手。被人卖了还帮人数钱?苦笑。
 
前几天,发现住处附近的好德便利里面的阿姨,总是时不时地出错多收你两三块钱。一开始还以为他们是不小心出错,连续留心了两天后,发现那彻彻底底就是计划预谋好了的。我靠。

我这两天莫名地超级工作效率低下。姑且,将脑子里的脏东西往外倒一倒打发一下时间。

想不出题目,就叫无题吧。
