Blind touch - I understand UML
Dragoner: What is the blind? What do you want to say? Thunder: Don't worry, listen to me slowly. The story of the blind people should have heard. It is probably like this. "Don't you say that I am in order to figure out what the elephant is like, so I am going to conduct a field visit. They find a big picture, I have touched it, I have touched it. Then expand the debate. Said: Elephant is like a thick wall (he touches the body of an elephant) B said: Elephant is like a pillar (he touches the legs of the elephant): Elephant is like a coarse tube ( He touched the nose of an elephant) Ding said: "Who is it right? Obviously there are places where it is, but it is not complete. Donoth: Luo Wei, what do you want to say? Thunder: I want to say this. Through this story, we understand a few truths, set to UML (unified modeling language) I have drawn two views. Viewpoint 1, UML can help us have a comprehensive understanding of the entire system. Modeling is to establish a model, such as we go to buy a house, there will be sand table models, renderings, account diagrams, etc. to give us a reference, although the house is delivered, we can also understand. The software system is also the same, if we have a software model, then we can show the various functions of the system's user, or to map the user's business needs to the development team, making developers to understand. The most important point is that our system is well design, which can display how the system works at multiple levels and perspectives. Let us understand the entire elephant, not a feet of an elephant. Make us not to create a blind touch. View point 2, if you look UML as an elephant, I am a blind. UML is actually an advanced idea. Everyone's knowledge background is different, and it will have different views. And you want to clear your understanding and opinion, sometimes it is very difficult. It seems that you are as difficult as you give the blind. I'm thinking about this level of things relying on my own understanding, not reading books. Of course, it is even more impossible to read the book. So in the process of learning UML, I am always reminding yourself, I am a blind person, my understanding may be a one-sided, someone's view I must study carefully, and must exceed UML, go to understand the construction The idea of model. Dramatics: It turns out that you have to say this, but you seem to have some discriminatory blind people. Thunder: No, I absolutely don't discriminate against the blind, I admire some blind people. Because they look at things, they are not using their eyes. And it is often more expensive than our glance.
