In the recent review of object-oriented, I saw a book: Object Oriented holy canon, Ali is a person to write the contents of the book is very detailed, vivid, many places have seen the feeling enlightened, seeing when demand analysis section, including one about the use case diagram of the design, which the author in this chapter is not recommended to build UML modeling use cases, because the language is a graphical UML modeling nature, and describe the details of each process with the need for more words to similar cases, which reminds me of previous learning UML modeling scene.
When studying at the University of UML modeling, UML is first of all do not know what to do, so the first step is to recognize UML, UML modeling that is what is used to do, and then carefully study UML modeling, please note I wording above, is to learn my language - UML modeling, UML modeling itself but merely a tool, UML modeling is in demand after the analysis is completed, the designer will use UML throughout the process of drawing up demand, so build UML mold itself and there is nothing to learn, how to understand this sentence it? Now if there is a hammer, then we need to use a hammer to hit a nail, so you do need to be careful of skilled learning to use a hammer, then go hit the nail right? Of course, the purpose is not to hit a nail, a hammer is a tool, a hammer is a tool, the best way to use a hammer is a human instinct, that is your favorite most comfortable position is the best way to use a hammer, which does not need by learning, and more hit a few nails will understand how to use it, and that is a UML modeling tool, do not need to recite What is the meaning of those icons, arrows What does it mean, the most important thing is to use it, but we have this in a university environment conditions do? This condition has to do to complete a project? No, we are listening to the teacher said in class: Today we learn UML modeling, then what does it mean this figure, that figure represents what it meant, so I Tucao teaching quality teacher, before I consider myself not learn is their own reasons, but now I find that a lot of the time, teachers do not know what they are education, corruption has long been extended to the field of education, and then review the following teaching English, English 6 why many people already difficult and foreign direct communicate with people, because we always put itself as an English learning to learn, then English is just a tool, it is the best way to learn is the actual practice nothing more, we have drawn English and English alone actually used to leave become a science in itself, but you do not need to master this knowledge directly communicate with foreigners, but you only need to understand the English law of induction by the Chinese themselves, to master these laws, you can meet the test, as for the English real role teachers do not care about, in fact, can be extended to many areas, education is not all disciplines In order to let you really master it, but in order to meet the test, so Now look, if the eight-legged essay of the Ming and Qing imagine the scene? Confucianism has long lost its original appearance, people learn not to truly master the Confucian Confucian, but to an officer, it is apparent that without studying the essence, but only use this idea had been around for 600 years, melting into the blood of our people inside, and very often even unaware of any problems.
But I am also a collective, my thoughts will be the existence of such utilitarian thinking, a lot of time learning when not to truly master this knowledge, but only for our own use, or that my heart did not want as I used too, but only this approach to learning has become my default way of learning that do not understand this whole subject of what to do, but simply recite every detail of this discipline, which meet the test of course icebreaker, but if still in this way to learn the real work, then sooner or later will be eliminated, it should be the real purpose of learning to master this knowledge, the final analysis, knowledge, human instinct for unknown explore.
When everyone is thinking this time, and that most of them are difficult to grasp what they are learning, which is reflected in the overall population of dull, poor performance at the national competition, perhaps those who are not a genius because a very young age have learned the essence of their fields, thus avoiding the problems tainted with this idea to learn a nation, thus avoiding the generation of the tragedy, the original genius is normal, but the general public but is this is the essence of the idea does not seek to deceive the minds of people.
