After class ended at 5:30 pm, Su Xiaomu left the school with his backpack.
The day went well, at least I had more opportunities to use spoken English.
Fortunately, knowing a foreign language is a skill.
When we got back to the den, the landlady hadn't come back yet, but she sent a message in advance saying that she wouldn't be home for another 20 minutes, so Su Xiaomu didn't have to worry.
Su Xiaomu replied "oh".
Carelessly.
Su Xiaomu didn't realize whether it would make the landlady so angry that she vomited blood.
Su Xiaomu, who was sitting on the sofa in the living room, thought for a while and called out the small garbage system.
I looked at the remaining points income: 980.
I flicked the points mall with my fingers, and flames appeared in the gray sky.
"The second flame."
Su Xiaomu was a little surprised.
The basic computer binary formula has brought him far more than the fifth place in the 64K demo competition and the reward of 6,000 US dollars.
It also creates more possibilities for his future.
The binary system is the basic system used by current computer systems and can be regarded as the basis for all operations that rely on computers.
No matter what method is used, the final feedback received by the machine itself is 0 and 1 expressed in binary. Different approaches lead to the same goal.
The understanding of the basic binary formula is actually the understanding of the more convenient control of the computer itself, and the foundation stone must be solid to build a high-level building.
After all, no one these days particularly wants to take the time to understand binary itself...
Looking at this second flame, Su Xiaomu also wanted to know, is this system that has somehow become so popular, should it continue on a path related to computer science, or is it planning to show off to the sky?
Or is there something else?
The six words "extraordinarily serious operation" and "showing off" with a numb scalp are basically equivalent to "coquettish".
If it is a perfect assistant...
Then I saw the introduction of the new flame:
[Basic principles of data warehouse and data mining]
Price: 680 points.
This time I didn’t get to experience the purchase price.
However, Su Xiaomu hesitated. He knew the terms data warehouse and data mining. This course was offered in the second year of his undergraduate program in Computer Science and Technology.
However, the proportion is very low.
Su Xiaomu had never had a class before changing classes.
These two things combined almost exclusively serve commercial enterprises;
Just like a data warehouse, simply put, it is a warehouse that reflects the accumulation of existing and historical business data of an enterprise and is used to support management decisions.
Data mining is the process of extracting information and knowledge that is implicit in it, that people do not know in advance, but is potentially useful, from a large amount of incomplete, noisy, fuzzy, and random practical application data.
.
More simply, through data mining and analysis of enterprise business data collected by the data warehouse, we can know which products are more popular and which products should be removed from the shelves.
Similar to a more fashionable word: big data.
However, the widely recognized definition of big data has one point: it must be data with a volume of data reaching the petabyte level. ①
Therefore, data warehouse and data mining alone are not equal to big data, and big data is not traditional data warehouse and data mining.
What Su Xiaomu hesitates about is the application and practical significance of data warehouse and data mining in some business fields:
But this has nothing to do with him. He is just a child, and the content on the curriculum is almost enough to broaden his horizons.
In addition, the current points balance is only 20 points away from the 1,000 points in the lottery.
A little itchy.
Draw a lottery and prove your pedigree!
Use 680 points to exchange for a basic principle that cannot be used now but will be used in the long future, although it is the path of computer science...
However, Su Xiaomu, who is used to being poor, really has to think about it.
There is no chance to get bonus points now, so be careful!
"Exchange it for me quickly, or I'll beat you to death!"
Su Xiaomu said fiercely.
[The redemption is successful, 680 points are deducted, leaving 300 points.]
Looking at the darker and longer flames on the barrage, Su Xiaomu was about to poke a wave when the door was knocked.
"I'm coming."
Su Xiaomu hurriedly opened the door, wondering why she would knock on the door if there was a doorbell. Wouldn't her hand hurt?
When I opened the door, I saw the cold Soho.
Su Xiaomu said with a playful smile, "Ah, the landlord is back, thank you for your hard work."
Su Ho snorted and went to open the door of 601 while saying, "Huh, you little gangster, why did you leave without saying hello this morning? I didn't know you were gone until you made breakfast!"
"You didn't follow me either..." As soon as Su Xiaomu said the words, he realized something was wrong. He hurriedly tried to take it back, but still couldn't take it back.
He just remembered that after dinner last night, the landlady said that he would have some porridge tomorrow morning.
Su Ho looked at Su Xiaomu with the white part of his big eyes, "Ha! You only have memory when you are acting like a gangster!"
…………
This person is really a social animal. When Su Xiaomu ate alone in the school cafeteria before, he didn't feel anything different. Wasn't it just to meet the body's necessary nutritional intake?
Now he knew that he was wrong. Looking at Su Ho who was busy in the kitchen, Su Xiaomu suddenly understood that the word life actually meant something.
"You studied in an all-English class at the Bachelor's and Master's degrees in Accounting from South China University of Technology. Your English is pretty good?"
While eating, Su Ho asked casually.
"You eat without talking or sleep without talking."
Su Xiaomu lowered his head to pick up the rice, his face expressionless.
Su Ho was so angry, "You!"
When I had dinner yesterday, I didn’t see you eating without saying a word!
"I just transferred to another class to make up for it. My English is average and my final score is 61." Su Xiaomu had to answer truthfully.
It's not easy to multiply by ten either.
Su Ho smiled so happily that he forgot about the cold bullying he received from the Internet in the afternoon.
Oh oh oh, it’s shameless to be a girl?...
After eating, Su Ho muttered, "Let's find a master tomorrow to remove the partition in the middle. It will be convenient."
When Su Xiaomu heard this, he really meant it. He looked at Su Ho with amusement, "Aren't you afraid? Do you really want to have a non-anxious dream together?"
Su Ho looked at Su Xiaomu up and down several times, "Can I lend you some courage?"
Su Xiaomu told herself that even a man cannot be a coward, he must...
Must be cowardly.
The landlady is still very fierce, no, knock her chest!
…………
…………
After returning to his own 603, Su Xiaomu pulled out the system.
The flame is still jumping in place, and the more you look at it, the more it looks like the dance of a famous internet celebrity——...
With the first mental preparation, Su Xiaomu specially told himself that men in science and engineering should be strong, not timid, and break at the critical place.
There are always more solutions than problems!
He stirred up a small flame, and the dimmed flame spurted out lines of text:
Like last time, start with the most basic concepts:
A data warehouse is a subject-oriented, integrated, stable, and time-oriented collection of data.
…
Data mining is an interdisciplinary subject that elevates people's application of data from low-level simple queries to mining knowledge from data and providing decision support.
…
In the least up and down places, there are the same six points:

Broken bowl.
I went to the hospital and saw a doctor. I had conjunctivitis in my eyes. It was not serious. I washed my eyes and put eye drops. However, I have used my eyes less to look at computers and mobile phones in the past two days, so there are less updates, such as...
