Savez-vous ce qu’est le big data ? Savez-vous quel en est son but premier et pourquoi ? Depuis le début d’Internet, toutes les données de navigations et autres sont stockées un peu partout dans le monde sur des centaines des serveurs différents et parfois même là où on ne les attend pas. Nous allons voir ensemble à quoi et comment sont utilisées ces données.
Tout d’abord, qu’est-ce que c’est ? L’idée principale du BigData est + ou – comme celle des cookies, c’est-à-dire enregistrer beaucoup de données, le plus possible (d’où sont nom : « Grande données » / « Données importantes » (en français).
Voici un petit tableau expliquant les volumes de données enregistrées dans le monde entier par période.
Période
Volume
… à 2003
5 exabytes (soit 5 millions de To / 5 milliards de Go) sont enregistrées
En 2011
5 EB (exabytes) étaient produits et récoltés en seulement 2 jours
En 2013
5 EB étaient produits et récoltés en seulement 10 minutes
Ce tableau provient du site : Culture-Informatique
Imaginez ce que cela peut représenté, surtout que maintenant, tout le monde possède généralement un smartphone en plus de son ordinateur, qui utilise lui aussi beaucoup de données.
La ou le bigdata est différent des cookies, c’est que les cookies sont des données de navigations web, et peuvent être effacées, contrairement au BigData.
Qu’est-ce que le Big Data enregistre ?
Quelques petits exemple :
Les sites web sur lesquels vous vous rendez
Les applications de votre smartphone
Vos conversations téléphoniques
Les mails que vous recevez
Les recherches que vous effectués
Vos achats sur internet (afin d’avoir vos centre d’intérêts)
Tout ce qui se connecte et utilise internet en soit… ! Vous ne vous en doutez peut-être pas, mais le B.D enregistre également :
Votre GPS
Tous les appareils connectés de votre domicile et / ou bureau
Vos thermostats (s’ils sont possibles à régler à distance)
etc … (tout les appareils utilisant Internet)
Mais quel en est son objectif ?
L’objectif du BigData est de collecter vos données afin de connaître d’avantages le consommateur pour ensuite lui proposer des produits / services adaptés à vos besoins, envies et recherches précédentes.
Comment sont stockées toutes ces données ?
Le stockage d’un tel volume de données est un travail rigoureux. Normalement, pour stocker un volume de données importantes, on utilise des bases de données (COMING SOON). Le problème est que la taille des données est tellement importante actuellement que ce n’était pas possible, il aura fallu penser à changer toute la manière de stockage… Et c’est à ce moment qu’on créa la règles des 5 V :
Volume : Stocker un maximum d’informations
Variété : Stocker beaucoup de données de toute sortes
Vélocité : Avoir un accès rapidement à toutes ces données
Véracité : Les données doivent être vraies
Valeur : Ces données doivent apporter de la valeur On pourrait y ajouter aussi :
Vertu : Ces données respectent les règlementations en vigueur
En conclusion
Nous pouvons dire qu’il est important de faire attention à nos données et à comment elles pourraient être utilisées. Nous ne pouvons malheureusement pas y faire grand chose, contrairement au cookies (C’est quoi les cookies ?)

vous avez une question particulière à laquelle nous n'avons pas répondu ?
Posez-là nous ici !
Whether you can understand it or not, that s the truth.The so called three people naturally do not include Xi Lerong.
Even though Wei Qingqi and Du Niansha were very determined, they were speechless for a long time as their spirits flew by.It almost hit the flaw that Gui Wujiu s triple paddle wheel had broken through by Xi Lerong and had not yet recovered.
And these four attacks are not just harassment. Each attack has the combat power of a top Taoist realm.As soon as Gui Wujiu s figure disappeared, he was already drifting indifferently from this world, not knowing where he ended up.
The vast charm of shamanism and the small sword in the turbid sky formed a unique fusion.His Taoism was profound and profound, and he was obviously superior to himself.
But the method demonstrated by Gui Wu Guo was so miraculous that each of them was intoxicated and lingered for a long time.To say the least, even if the third level of Ping Wheel is not added, just the strengthening of Qi after Gui Wujiu s real breakthrough is already too much for the Ping Wheel magical power that is extremely sensitive to strength and weakness.
But about half an hour later, he sensed clearly that the man was blocking him again.Now, Qin Menglin has made up for this step. In fact, the fundamental Taoist techniques of each sect are not visible if they are not the true teachings of the sect but now there is no obstacle to Gui Wujia breaking the rules.
Zhang Xuan s whole body froze, and his whole body seemed to transform into heaven in an instant, soaring above the nine heavens.Anyone who used his magical powers later or changed his moves midway would lose a layer of momentum and fall at a disadvantage in the face of his subtle methods.
Within ten years, it was enough to refine dozens of Yin Yang Cave Heavens to fill the gaps in the Holy Religion.After more than a hundred breaths, Gui Wujiu shook his head and smiled, and said I understand.
Instead, the atmosphere suddenly changed, from joy to vigilance.And a wonderful force overflowed from the gap between his five fingers, and in an instant a wave of bows and arrows was formed, which was the method of doubling the power.
The formation of the array of magical powers is still the same as the previous method.In the following ten years, he conquered all over the world and rapidly expanded his sphere of influence.
Gui Wujiu, Qin Menglin, and Huang Xiyin jumped up and stood on the top of the mountain.One wave causes thousands of waves to follow. From a macro perspective, the top figure of a generation is like the head of the flying geese formation, which will have an unstoppable impact on the other heroes of the same generation.
Then he resisted with high speed and smashed the densest flying stone fire balls one by one, intercepting most of them.As for Qin Menglin s ability to reach this point, there are too many incredible variables hidden in it.
The time is ripe for acquittal. He took a step forward and said Friend Qingdao, you can rest assured.Just when he was thinking this, there was a flower in front of him.
In order to ensure his perfect state, he can fight with all his strength.The person in front of him shook his head, half curious, half excited, with a hint of ill intention in his eyes, and said loudly You are not to blame The moment he spoke, his magic power gradually became more powerful.
But in fact, the physical properties of heaven and earth have their own limits.When it comes to the subtleties of Taoism Precise and mysterious, it is actually Yin and Yang Dao that is the leader.
Shentu Longshu said calmly Friend Huang, what do you want from this trip Huang Xiyin did not speak directly, but looked at Shentu carefully.As a result, his reputation and luck gradually deteriorated.
Mr. Xin Ming certainly knows that although this Eight Swords in One in fact, the name may not be appropriate, it is very different from the Eight Swords in One in popular understanding although it is extremely powerful, Gui Wugui can also deal with it.It can be clearly seen that although the two of them are fighting in the air, as long as they drop slightly and reach a height that is less than ten thousand miles away from the ground, except for the place where Xi Lerong has already laid out the forbidden formation, the rest of the ground is made of earth and stone no matter how hard it is.
Meditate and practice to adjust your state. Although he didn t go out, Qingyang paid attention to what was going on outside.The results fed back by the two were similar to Qingyang s predictions.
A cold light flashed in Hua Qingyao s eyes. He just paused in the air for a moment, and then rushed towards the golden elixir monk at a faster speed.The huge inkstone fell to the ground. The middle aged scribe in front flicked his sleeves, stepped out of the inkstone with both feet, and walked towards everyone in the air with his whole body.
There are so many monks in the world, and their attack methods are not fixed.Seeing the third level living dead knocking Yin Yang Slash away with one move, he couldn t help but secretly marveled at how powerful he was.
Anyway, more than sixty years have passed, so there is no need to rush into this matter, just look for it slowly.Is it because my qualifications are not good Nor, although I, a Qingjing Sanren, are not good enough.
Because of the long term cultivation of the Concentration Art, the intensity of Qingyang s spiritual thoughts is much higher than that of monks of the same level.The trip up was well worth it. Qingyang sighed a few words and put the entire eagle s nest into the talisman before climbing down from the stone peak along the original path.
When Li Shengbo decided to take action, it was because of the idea of retribution.A cave was dug out. The mountain wall is so smooth that there is almost no place to rely on.
Perhaps the old Taoist priest was really good at gambling.Occasionally Qingyang will give him some spiritual pollen or spiritual flower nectar, and sometimes miscellaneous pills that Qingyang himself does not like.
This will be the result. He said calmly, Fellow Daoist Duan, you don t need to be so restrained.Some of it must be added when refining elixirs for improving cultivation at each level.
I originally thought it was a hard job, but I didn t expect to get the late stage foundation building blood spirit beads that Qi Refining monks dream of.You killed Liang Qingtian with just one move. Now you are shouting to kill the head of the Liang family.
If it had been before, Qingyang might have taken a detour if he didn t want to cause trouble.Qingyang and others were happy to be quiet, so they sat there drinking tea and chatting while waiting for the Jindan Conference to start.
The sequelae of Qingyang s blood burning surgery have long since receded, and most of his internal injuries have healed.The main reason was that the items of the foundation building monks were too valuable and the Qi refining monks couldn t afford them.
The price was a bit high. It wasn t that he couldn t afford the spiritual stone, but that the price was at least 20 to 30 higher than the price outside.But even the masters were dispatched, so it shouldn t be too difficult.
A foundation building monk made as many as a dozen or as few as seven or eight blood spirit beads before he died.The name of the sword owned by Soul Seducer Sang Fan is called Hantan Sword.
Only Lu Dingshan s injury is slightly more serious, which may affect his performance.I can testify for him. On the third day after the Blood River Secret Palace was discovered, Junior Brother Qingyang followed We met at the river, and we took turns breaking the formation for the next half month.
it should not leak anything. As for whether this guy will take revenge in the future, Qingyang is not afraid of him now, will he still be afraid of him in the future He looked in the direction where the seducer Sang Fan was escaping.I didn t expect Ouyang Jing to catch up with me, and I don t know what method he used.
Because of this, there was no one around to chat with them.This luck can be described as unparalleled. Many trial disciples can t help but daydream, how wonderful it would be if they were the one who encountered the third level living dead The thousand year old elixir is his own, which will bring great glory to the sect, and he can also be in the limelight.
Behind the bearded man, there were dozens of monks, some of whom were also cultivated in the Golden Core.On this day, Qingyang once again encountered a group of trial disciples.
At this moment, someone suddenly said, You Qingfeng Palace really spent a lot of money on the elixir worth more than 10,000 spiritual stones.Ordinary pills no longer have much effect on him, but Qingyang s Linghua Honey does not have this shortcoming, so he After seeing Qingyang s Spirit Flower Honey in the auditorium, I came here directly.
After taking back the magic weapon, all the golden elixir monks completely relaxed.When Tao Youcheng died, he fell into the blood pool, so his blood became the nutrition of the blood lotus root.
There was little news about the Moon God, but it was intercepted by Varok s Domain of the Dead.With an unpleasant sound of squeaking , the incarnation made of magic power showed a very weird distortion.
It gathered crazily towards the center and was instilled into Nicolu s body.In his expectation, Anthony was the most dangerous moment in this promotion ceremony, because the opponent had only become a sixth ring grand wizard for a short period of time, less than two years, and the other selected grand wizards had basically already set foot in the process.
After all, someone just threw the tritium crystal as a snack like a dog training.There were all trustworthy people present, and Linn did not hide the principles of the new fighter plane, so he introduced Dennis s explosive thruster emphatically.
IQ. The wizards in the large exhibition hall also had difficulty understanding this so called wave particle duality.Since everyone has no objections, let s continue to follow Speaker Linn s cleanup plan.
We d better go take a look Vittorio suggested. If anyone can answer this question, it s probably Lynn who proposed the theory of relativity
At the same time, a large group of wizards were arguing with each other in front of a luxurious manor.Sean nodded with great satisfaction. His self created cleaning magic seemed to be perfect and he just needed to name it.
Please forgive me for disturbing your sleep, Your Majesty the Duke.End of Chapter Since many wizards were very interested in this new realm, Linn briefly described some of God s characteristics and non confidential information.
Another function of this magical technique is to share perception.Naturally, the only Corona Medal was awarded to Linn.
Aurora said in agreement. Of course there are elements that are much smaller than basic atoms, such as thunder elements, light elements, and those elemental ghosts
But they couldn t sense them before, so they couldn t be sure whether these elements really existed.this may be the reason why the other party can easily affect and distort time and space.
Let s fly with the planet
Fly to the boundless void of the universe and run towards true freedom Lin En was just a little short of taking action.I remember that he recently stopped in the City of Fire and Oil.
The second step is to explain all this with a planetary orbit model that is relatively easy to understand.I have no way to confirm the authenticity. Vittorio s expression was no better than that of Linn and others.
Three bottomless depressions first appeared on the ground, and expanded at a speed visible to the naked eye.Having regained his ability to move, Harrov, who was closest to the source of the explosion, covered his chest and coughed violently.
Although the great Moon God has some response to our devout prayers day and night, the end is not over yet.They were obviously The last batch arrived, and tens of thousands of wizards had already gathered in the huge exhibition hall, exchanging and talking about their insights and research in various fields of magic.
As for how to defeat Ella , Lin En already had some ideas in mind.Lucia only felt a fear that penetrated into her soul, and then she fell into darkness
This was not the darkness created by the nuclear explosion.
It is enough to understand the commands and know how to handle some daily tasks.What restrained the powerful monster was an alchemical creation called a fighter plane, and its driver was a halfling like himself.
Vittorio left After that, he temporarily took over the duties of dean.Where s the charge Where did the charge go Roll and Glenn looked at each other, and a chill suddenly surged into their hearts from the soles of their feet.
Even the magic network cannot connect there, and Raphael cannot cover everything, and all actions must be done consciously.Waves of violent, eardrum shattering roars resounded in the underground space The simple bronze door and Cynthia behind it were both caught in the hot fire at the same moment.
If he was lucky enough, he might have a chance of winning in the end.When I was in Yingyuan, I crossed hundreds of feet of yellow spring water.
Unexpectedly, they were not lucky enough. They encountered a group of forest beasts.My master is indeed not here. He Ever since the old man broke through the realm of divine transformation, the dragon has rarely seen its head but not its tail, and it has been rare to see it for decades.
Therefore, except for a few people in Baimei City who knew that Qingyang was not as simple as he appeared, the other monks in the team only regarded Qingyang as an ordinary Jindan monk, and it was difficult to notice him.Big, he questioned You are not my queen, why should I bow to you Hearing this, Baimei Ghost King was stunned for a moment.
It seems that it is not easy to impress the Long Eyebrow Ghost King.And the battles not only take place inside and outside the city walls, there are battlefields in the air, underground, and throughout Funiu City.
He was just the son of a small city lord who was a casual cultivator.After hearing what the two said, everyone realized that there was indeed something abnormal about this white haired old woman.
The True Ten Kings Sealing Formation is a formation they set up with their own bodies.After thinking about it, you were the only one, Shuangxi Ghost King You were in my mansion back then.
It was a little slower and only then did I catch up.The Giant Ghost King and the Long Eyebrow Ghost King were very fast and arrived in front of the Baimei Ghost King in a blink of an eye.
In the past, Qingyang s cultivation level was low. At that time, I could give him a few pointers and he would benefit a lot.Those few months were the most comfortable period of her life.
This time he really found a treasure. The monks in Crouching Tiger City are all satisfied.The head of the Tian family Originally, he wanted to give some to Qingyang, but Qingyang didn t like these low level materials and he was determined not to want them.
If he cannot be beaten, he can escape. But there is a saying that if he escapes, the monk cannot escape the temple.After all, Qingyang s strength is still a little bit worse.
As a result, the one and the other increased. Qingyang, who was originally slightly weaker, actually suppressed the Nascent Soul followers of the Fuliu Ghost King in the battle, and clearly had the upper hand.The One Horned Ghost King Since he chose to come quietly, he couldn t spoil his affairs in a big way, so if he could, he d better not mention it.
However, this corpse eating mother worm can only be used once.Youdao said that the nights were long and the dreams were many.
If he retreats, he will die. Moreover, Fuliu Ghost King wants to establish his authority, so it is impossible for him to retreat.A huge stone tablet appeared in each of these ten positions.
Their number is very small. Most of the monks He had already left them far behind, and unknowingly he was standing at the top of the monks.Because high level monks are reluctant to leave their previous realms, their souls can still be preserved in the outside world for a long time, and they can slowly look for objects to seize their bodies.
The monster beast does not show weakness and shows its full strength.Only by using the Three Yuan Sword Formation in time could he block the previous attack.
After these spiders emerged from the ground, they aggressively attacked the monks next to them.During the thirty years in the cold cave, in addition to practicing, Qingyang also tried to use Yin Yang Xuan Gong.
No matter what the goals of both sides of the battle are, it cannot be solved by an outsider from Qingyang.
