Chapter 23 The Second Dancing Flame
After class ended at 5:30 p.m., Su Xiaomu left the school with his backpack.

This day is not bad, at least there are more opportunities to use spoken English.

Fortunately, knowing a foreign language and speaking it is also considered a skill.

Back in the small nest, the landlady hadn't come back yet, but she sent a message in advance that she would arrive home in 20 minutes, telling Su Xiaomu not to worry.

Su Xiaomu replied with an 'oh'.

casually.

Whether it would make the landlady vomit blood with anger, Su Xiaomu didn't have the corresponding consciousness.

Su Xiaomu, who was sitting on the sofa in the living room, thought about it and called out the small garbage system.

Looking at the remainder of the points income: 980.

He flicked the point mall with his fingers, and flames burst out of the gray mist.

"The second flame."

Su Xiaomu was a little surprised.

The computer binary basic sequence has brought him far more than the fifth place in the 64K demo competition and the reward of [-] 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 the binary representation of 0 and 1, which leads to the same goal by different routes.

The understanding of the binary basic column formula is actually an understanding of the more convenient manipulation of the computer itself, and a solid foundation is also needed for a high-rise building.

After all, no one is particularly willing to take the time to understand the binary itself these days...

Looking at the second flame, Su Xiaomu also wanted to know, is this system that has been made a show, is it going to continue on the path related to computer science, or is it going to show off to the sky?
Or is there something else?

The six words of abnormally serious operation plus the numbness of Xiu's scalp are basically equivalent to Sao.

If perfect assistance...

Then I saw the introduction of the new flame:

[Basic principles of data warehouse and data mining]

Price: 680 points.

This time, I did not experience the purchase price.

However, Su Xiaomu hesitated. He knew the two terms data warehouse and data mining. Computer Science and Technology was offered as a sophomore in a combined undergraduate and master's program.

But the proportion is very low.

Su Xiaomu had never had a class before changing classes.

The addition of these two things can almost only 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 hidden, unknown but potentially useful information and knowledge from a large amount of incomplete, noisy, fuzzy, and random practical application data. .

More simply, data mining and analysis is performed on the business data collected by the data warehouse to 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 thing: 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.

Su Xiaomu is hesitant about the application and practical significance of data warehouse and data mining in some business fields:

Merchandising, manufacturing, financial services/credit cards, telecommunications.

But this has nothing to do with him, he is just a child, and the content on the curriculum is almost enough for him to broaden his horizons.

In addition, the remaining points are only 1000 points away from the 20 points in the lottery.

A little itchy.

The lottery can also prove the lineage!
Use 680 points to exchange for a basic principle that is not used now, but will be used in the long future, although it is the way of computer science...

But 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!

"Hurry up and exchange it for me, or I will kill you!"

Su Xiaomu said viciously.

[The exchange is successful, 680 points will be 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 slammed.

"I'm coming."

Su Xiaomu hurriedly went to open the door, wondering why he had to knock on the door when there was a doorbell, his hand didn't hurt.

When I opened the door, I saw the cool Soho.

Su Xiaomu said with a playful smile, "Ah, the landlord is back, it's been hard work."

Su Ho snorted, and while going to open the door of 601, he said, "Hmph, you little rascal, why did you leave without saying hello in the morning, and you didn't know you were gone until you had breakfast!"

"You didn't follow me..." As soon as Su Xiaomu said the words, he realized that something was wrong, and he still couldn't take it back.

He just remembered that after dinner last night, the landlady said something to have some porridge tomorrow morning.

Su Ho looked at Su Xiaomu with the white part of his big eyes, "Oh! You only have a memory when you're a hooligan!"

…………

This person is really a social animal. When Su Xiaomu ate alone in the school cafeteria, he didn't feel any difference. Isn't it just to solve the necessary nutritional intake for the body?
Now he knew that he was wrong. Looking at Su He who was busy in the kitchen, Su Xiaomu suddenly understood that the word life actually had something to do with it.

"You are from South China University of Technology's combined undergraduate and master's program in the all-English class. Your English is pretty good?"

During the meal, Su Ho asked casually.

"Eat without a word or sleep without a word."

Su Xiaomu lowered his head to pick up the rice, 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.

Su Ho smiled, very happy, and forgot about being cold and violent on 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, and looked at Su Ho with a bit of playfulness, "Aren't you afraid? Do you really want to have that non-anxious dream together?"

Su Ho looked Su Xiaomu up and down several times, "May I borrow your guts?"

Su Xiaomu told himself that even a man can't be cowardly, he must...

Must be cowardly.

The landlady is still very fierce, no, knocking on the chest!

…………

…………

After returning to 603 on his side, Su Xiaomu pulled the system out.

The flame is still jumping in place, and the more it looks, the more it looks like a famous Internet celebrity dancing—…

With the mental preparation for the first time, Su Xiaomu specially told himself that men in science and engineering should be strong, not cowardly, and break at key points.

There are always more solutions than problems!
After flicking the small flame, the dimmed flame spewed out lines of text:

Like last time, let's start with the most basic concepts:
A data warehouse is: subject-oriented, integrated, stable, and time-oriented collection of data.

……

Data mining is an interdisciplinary subject, which improves 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 place, it is the same six points:
. . . . . .

①: 1PB=1024TB=1048576GB
======
Broken bowl.

I went to the hospital to see a doctor. I have conjunctivitis in my eyes. It’s not serious. I washed my eyes and put eye drops, but I have reduced my eyes to look at my computer and mobile phone in the past two days, so there are fewer updates, such as...

Three shifts today.
