What is big data and what changes it has brought us?

Ten pieces of information about large numbers:

1) Big data computing improves data processing efficiency and increases human cognitive surplus?

Big data technology, like other technological revolutions, starts with efficiency improvement. The emergence of big data technology platform improves the efficiency of data processing. Its efficiency has increased geometrically, and the data that used to take several days or even longer to process may now be completed in a few minutes.

The efficient computing power of big data saves more time for human beings. We all know that efficiency improvement is a typical symbol of the progress of human society, and it can be inferred that big data technology will lead human society to another stage. Using the time saved by big data computing, people can consume, entertain and create. In the future, big data computing will release the huge productivity of human society, increase the cognitive surplus of human beings and help human beings better transform the world. ?

2) Big data lets people know the truth behind things through global data?

Compared with past samples replacing all statistical methods, big data will use global data, and its statistical results will be more accurate, which will help scientists understand the truth behind things. The statistical results brought by big data will correct people's misunderstanding of things in the past, affect the conclusions of human behavior and social behavior in the past, and bring new cognition.

It is beneficial for the government, enterprises and scientists to understand the real reasons for various historical behaviors of human society in the past. Big data statistics will correct the statistical errors of samples and constantly correct statistical conclusions. Big data can bring people closer to understanding nature and increase their understanding of the causes of natural disasters. ?

3) Big data helps to understand the objective laws of the development of things and is conducive to scientific decision-making?

Big data collects global data, accurate data, calculates the truth in the development process of things through big data, and analyzes the development law of human society and nature through data. Using the analysis results provided by big data to summarize and deduce the development law of things, and helping people make scientific decisions by mastering the development law of things, precision marketing in the era of big data is a typical application. ?

4) Big data provides a connection with things and an objective understanding of human behavior?

Before the emergence of big data, the data we learned about human behavior often came from some passive survey forms and lagging statistical data. With big data technology, a large number of sensors, such as mobile apps, cameras, shared pictures and videos, let us understand human behavior more objectively.

Big data technology connects people's behavior, collects people's behavior data through big data, and counts people's behavior after some analysis to help us understand people's behavior. It can be said that an important role of big data is to collect and analyze human behavior data, understand the characteristics of human behavior, and provide basic assets for the commercial application of data value?

5) Big data changes past empirical thinking and helps people build data thinking?

The development of human society has always relied on data, whether it is the evolution of civilizations, agricultural planning, industrial development, military campaigns or political events in various countries.

But after the emergence of big data, we will encounter massive data, multidimensional data, behavioral data, emotional data and real-time data. These data were not known in the past. Through big data computing and analysis technology, people will get different things and different development laws.

Relying on the data analysis report provided by big data, people will find it no longer difficult to decide, judge and understand a thing. Governments and enterprises all over the world will use big data to understand people's needs, abandon past empirical thinking and inertial thinking, master objective laws, and jump out of historical difficulties to predict the future.

Big data development trend:

1) Trend 1: Resource of data?

What is recycling means that big data has become an important strategic resource for enterprises and society and has become a new focus for everyone to grab. Therefore, enterprises must make strategic planning of big data marketing in advance to seize market opportunities.

2) Trend 2: Deep integration with cloud computing?

Big data is inseparable from cloud processing, which provides flexible and extensible infrastructure for big data and is one of the platforms for generating big data. Since 20 13, big data technology and cloud computing technology have been closely integrated, and it is expected that the relationship between them will be closer in the future. In addition, emerging computing forms such as the Internet of Things and the mobile Internet will also help the big data revolution and make big data marketing exert greater influence.

3) Trend 3: Breakthrough of scientific theory?

With the rapid development of big data, just like computers and the Internet, big data is likely to be a new round of technological revolution. The related technologies such as data mining, machine learning and artificial intelligence may change many algorithms and basic theories in the data world and achieve scientific and technological breakthroughs.

Trend 4: The establishment of data science and data alliance?

In the future, data science will become a specialized subject and be recognized by more and more people. Major universities will set up specialized data science majors, which will also give birth to a number of new jobs related to them. At the same time, based on the basic platform of data, a cross-domain data sharing platform will be established. After that, data sharing will expand to the enterprise level and become the core of the future industry.

Big data analysis:?

There is an essential difference between big data analysis and traditional analysis, that is, traditional analysis is based on structured and relational data. And often take a small data set to predict and judge the whole data. But now is the era of big data, and the concept has completely changed. Today's big data analysis is to directly store and manage the entire data set.
