Record bed mania 

On Sunday, I slept more than in the morning, and there was no indication of bed. I feel like it is too much. Can this waste so much time for a young man? The so-called "one inch of time, one inch of gold!

I heard that when people are lying down, the amount of blood flowing through the brain is the most (someone says it is upside down. Don't use it if it's upside down. 1. I haven't reached that level yet. 2. I don't want to worry about congestion yet. It's not good if I get paralyzed or something .), More than sitting and standing. In combination with a good environment, the human thinking ability is the best at this time.

Now that you are in bed, you have to think about some meaningful things (I am a good citizen and I don't want to do these things ). When I got in touch with my work, I often thought about two problems (I also thought about it at ordinary times, but I was disturbed by the cumbersome work and life, and I was not completely calm down and thought about it, it seems that sometimes you have to drink jingxin oral liquid, haha ...) :

I. analysis, design, and implementation of an information system after excluding factors such as team communication and cooperation, system maintenance and upgrade, performance, security, stability, architecture and deployment, etc, what is the most direct and direct system design model (model? I think it is like this:

User operation interface (proportional operation interface) and other necessary technologies (such as Access Control controller call interface) + SQL + database (db)

The above thinking reminds me of the research methods of mathematics and physics in Middle School: Eliminate all interference factors and abstract the most primitive and fundamental things. For example, the second law of Newton dynamics should be studied. During Experiment verification, friction and wind resistance should be ruled out in many cases.

2. Why do the above model (model) mention or only database and SQL? Many information systems do not use databases as storage methods or do not have external storage methods. They also run well and are very moist. It is not universal or general. This model (pattern) is very unsuccessful. It seems like it's finished. Is that true? Let me talk about it slowly. First of all, remember, here is just a record of sentiment, not an academic paper. You don't have to be so aggressive! Second, the database and SQL mentioned in this model are just the alias for data storage and processing in the Information System (only this technology is much used now, I have to be represented at the "NPC and CPPCC" here, haha ...). Also, I dare say that all information systems now need to store data and process data. In the most exaggerated and worst cases, you have to store your own program files! Your program files are also data.

Now let's talk about other things. Recently I have nothing to do with reading scientific and educational films about the evolution of the universe and life on Earth. The most fundamental and abstract description of the discovery of the universe and life is "winning by volume and increasing storage capacity ".

First, the universe is huge. It takes about six minutes for the sun to reach the Earth. Imagine that the light would take six minutes every second for 0.3 million kilometers. The fastest human supersonic aircraft would not know how long it would take. It takes half a year for humans to reach Mars using existing technologies at the shortest distance. It is not known how long it will take to exit the solar system, it seems that an exsolar system detector launched in the early 1970s s in the United States is still flying in the solar system. In the Milky Way, there are trillions of stellar systems like the solar system (in short, more than all the ox hairs in the world ). In the universe, a galaxy like the Milky Way forms a total galaxy, With a number less than the number of hennets in the Milky Way. Now it's over. No, I heard there are other total galaxies outside of the total galaxy. What's more, there is no way to predict the number of things. How can this be endless! Is there any boundary in the universe! According to the old man hawking, the universe is boundless. It seems very mysterious to hear that we ordinary people cannot understand it. I have heard that we must have rich mathematical knowledge and multi-dimensional space-time concepts to understand it. We are now living in a long, wide, and high three-dimensional plus a half-dimension timeline. I still can understand this. Do you have any experience in life! However, today's physicists, physicists, and astronomers export the universe to 11 dimensions. This may be hard to understand for most people. It seems that the universe is very generous. It gives us such a large activity space for humans (the vast number of real estate companies and speculators on the earth want to speculate on the house, it seems that there will never be a chance in the vast universe, haha .....). There is no need to compete with aliens in such a large territory. Here, I want to talk about other things. I have heard that the legendary western economics is the contradiction between the scarcity of research resources and the endless desires of mankind. I doubt the above. The universe is so big that we can say that resources are scarce. We humans have never seen or touched anything in the universe. When will a great overflight of human thoughts, a great breakthrough in technology, and a great discovery of the Universe (similar to the geographic discoveries of Columbus in the past) Develop and utilize infinite resources in the universe, at that time, what we really wanted was what we had. We lived a fairy-like day and distributed on demand to realize communism, moving from the inevitable kingdom to the kingdom of freedom (suspending for three minutes, obscenity, envy ....). So I said that the old studies studying "Western Economics" are a bit confusing. Science and technology are the first force. It seems that this sentence is correct. I would like to add another sentence, science and technology are the first elements to promote economic development in the future. In the future, there should be a new economics course (hereinafter referred to as "cosmic Economics"), which is mainly used to study the contradiction between current incompetence and endless desires and the inability to develop and use infinite resources in the universe.

After talking about the big and wide universe, let's talk about the tiny and small atoms and basic particles that make up materials. I heard that there are 108 basic elements that humans know now (and it seems to be 109, I forgot ). A certain number of element atoms can form a single molecule. These super-large numbers of molecules constitute what we see in our eyes. For example, a drop of water is composed of hundreds of millions of water molecules. Countless drops of water make up the water we use in production and life. It can be seen that the composition of the universe is sometimes simple and simple-"winning by quantity ".

Now the longest-lived animal in the world is known as a turtle. It is said that it can live in its one thousand S, but its longevity secrets are: less activity, less thinking, and less metabolism. This is similar to the practice of a monk in the past. For me, I don't want to live such a way of life. I 'd rather have a shorter life than I would have to live. However, the evolution of turtles over the past one thousand years is not worth mentioning. Human Tail removal has evolved over millions of years. In addition, if our solar system accidentally flew to the black hole, it would take millions of years for the whole solar system to be completely swallowed up by the black hole, during this period, humans and other living and dead things are suffering and even more terrible than living in hell-in the earth, due to the powerful gravity of the black hole, frequent earthquakes and volcanic outbreaks have changed the Earth's shape. The huge meteorite in space affected by the gravity of the black hole has attacked the earth in large numbers, and the atmosphere will no longer be able to protect us; the original Sun giving life to the Earth has become unamiable because of the black hole gravity. It is frequently opening harmful substances and rays to the Earth; before the last Earth is swallowed up by a black hole, it is torn apart by the high temperature and frequent geological movements of the earth. However, most of these scenes can be seen by future humans, in addition, it seems that more than 1 million years has allowed humans to endure suffering and terror for a long time. It can be seen from this that nature sometimes seems to be too unenforceable, and it is a drag-and-drop thing, whether it is a good thing or a bad thing. I can't describe it with "slow track" at all.

Okay, so many topics should be taken back. I think the database technology in information technology is very consistent with the basic description of the universe and life in terms of "being tolerant, winning by quantity, and being slow. Large database data storage capacity, wide data storage range, and complex storage data structures and categories. If we need to build a virtual universe in the computer information system that day, I think using the database (ultra-large-scale data storage) technology is the best technical solution, because it contains the most basic attributes of the description of the universe and life. I remember a person in charge of IBM China's DB2 department saying: "An information system with large amounts of data is a mature and successful system, it is a system that can be used for application promotion. (in this case, the person in charge is a female. I wrote this article on the Women's Day. I would like to give it a thumbs up first ). Large-scale data storage and processing technology (especially the current database technology) is a simulation and replication of the real universe.
