What exactly is a design pattern?

What is a pattern, this is a seemingly simple, but very simple question. I've seen a lot of people, learning model theory for a long time, but I don't really understand that.

The basic idea of pattern theory originated in China, which is the inherent thought of Chinese culture. You, me, every one of us who was nurtured by Chinese thought from a childhood, naturally has this basic idea. The idea of pattern exists in every corner of Chinese culture, including philosophy, law, medicine, Art of war, sports, literature, until we behave in a manner.

The thought of pattern, which has not existed in the Western way of thinking for a long time, is not the mainstream thought of Western culture. Therefore, learn the mode, avoid the West way of thinking learning. Otherwise, impossible, the effort.

Simply put, the so-called pattern, is a good example of the study. Design patterns are examples of design. In the Art of War, Sun Tzu is full of patterns. Grandson said, "As for the death and the epigenetic" is the mode of warfare. 36, all are models, such as "Go for", "Kongchengji" is also a war model.

Each of these patterns has a typical meaning and is of learning value. By studying these patterns, learners can communicate with each other, and they can extrapolate, innovate and apply them in their own practice.

When we take part in the college entrance examination, the teacher gives us a lot of typical questions, as practice use. These topics are generally not in the college entrance examination, but these topics will inspire us to think, can let us extrapolate, so as to prepare for the exam.

The pattern is not a frame (framework), nor a procedure. The pattern is also not a simple "problem solution", because the pattern must be a solution to a typical problem, an example of a extrapolate, research-worthy, communicative value, with its own name.

mode cannot be applied. Do not assume that certain design patterns are used in any one system. The design of the system is not the same as the design mode, but not the more the design pattern is better.

In the "Three Kingdoms", Ma Yi applied the "As for the death and epigenetic" mode of warfare, finally poured a big mold. In the college entrance examination, if you put the teacher to your typical question answers to recite, in one to test papers up, put more, I am afraid you will be away from the university.

For example, if you like 36, if you are in the execution of a certain military tasks, do everything possible to use as many as 36 to the inside, each time to a "walk", then your friends and enemies will feel a wonderful. If you do not use the 36 plan, or think that the strategy in the 36 is not a good strategy, then others can only think you do not understand the essence of 36.

Traditional Chinese medicine is the same, sometimes appear similar symptoms of the disease, but to use a different prescription, that is, the so-called syndrome differentiation drug. If every time you treat a patient, you must hold out a certain medical case, will be as many famous medical cases as possible to your patients, I am afraid it will not be long before the big trouble.

The ancient law of China is the case law, which requires the judge to extrapolate and play the proper role on the basis of the learning case. A joke, if you like the "rolling the United States case", the United States will be rolling, I am afraid that we need to prepare the line early.
