Watching flowers in the fog-What blinded your sight?

The problem I encountered recently is that I was confused when I watched a dozen sets of database videos. A kind of database stuff seems like a thin air. I wanted to look for this database textbook first, but I felt that the materials on the superstar were not very useful. I finally gave up, and I didn't care about it. It was not until today that I had taken a course by Mr. Mi that I suddenly realized that my heart was lost because I didn't create a directory for the database knowledge in my mind, so what I learned was not home to me, that's why I feel guilty. Then, I looked back at my learning experience and found it was like this!

Teacher Mi once again uses the story of "walking in the forest" to tell us the truth: learning requires macro control, so that it is not lost. After learning, knowledge can truly belong to you. I learned data in the previous section, as shown in Figure 1. I met a knowledge point and formed a knot. At last, there were many knots on the rope, but it was still a straight line. The knowledge structure was one-dimensional. This is like a database without indexes. It only has the functionality of disgusting people and is not practical at all. The so-called macro control is to first create a two-dimensional or higher main architecture in your mind, that is, a directory, which is like a subject created before building a house. Then you can improve your architecture through learning, which is the process of building walls. In this way, your knowledge structure is a two-dimensional network 2, which is not easy to lose. After the establishment of the Knowledge Network, the directory becomes the index in your knowledge database, which is also convenient to use. It provides more interfaces for you to access the knowledge database.

 

In the above explanation, Do you think learning is like this? No, this is not enough. Teacher mi will teach us more than this!

First of all, I recently discovered that things in the database are very similar to the knowledge in VB. It is reasonable to use the concepts in VB to explain some knowledge in the database. This is why I understand that Mr Mi advocates that programming should start with VB. This is because the concept in VB is not as hard to understand as in other languages, and it is relatively easy for cainiao to teach other languages. The second reason is that after learning VB, it is helpful to understand the concepts of other languages and migrate through learning. In fact, the process of learning VB is to create a directory in your mind without knowing it. At the same time, this directory is still a class, which provides nodes for your learning of other knowledge. One sentence is to help the Group process new knowledge!

Besides our time management, do you think there is a relationship between time management and macro control? Think about the folders in my Foxmail. What is it like? That's right, it's a directory. In fact, time management also creates an architecture, but its object is your life. This directory receives all the things and returns them to each folder after processing. This is another class. This directory makes your life organized, so you are confused, so you have no choice but to be efficient.

What should I do next? The instructor said in the quick reading class. Then you can learn English! Can you understand the relationship between English learning and macro control? Where is its directory? Well, this time I also feel that there is no directory for learning English, because the document says that language cannot be treated as knowledge.

Well, to sum up, I think the learning of knowledge can be shown in the following illustration:
