The world contains an unimaginable amount of digital information, and it is becoming faster and faster ... from business to science, from government to art, this influence is everywhere. Scientists and computer engineers have created a model for this phenomenon.

New term: teasing big data. What does the era of big data mean? What does the concept of big data mean? What does the analysis of big data mean? What is the so-called big data? What is its origin and definition?

Look at it.

One: the definition of big data.

1. Big data, also known as huge data, refers to information that involves so much data that it cannot be captured, managed, processed and arranged by human brains or even mainstream software tools to help enterprises make more active decisions within a reasonable time.

2. Big data technology refers to the technical ability to quickly obtain valuable information from all kinds of big data, including data collection, storage, management, analysis and mining, visualization and other technologies and their integration. Suitable for big data

Technology, including large-scale parallel processing (MPP) database, data mining power grid, distributed file system, distributed database, cloud computing platform, Internet and extensible storage system.

The Internet is a magical big network, and the development of big data is also a model. If you really want to know about big data, you can come here. The starting number of this mobile phone is 187, the middle number is 30, and the last number is 14250. You can find it by combining them in order. What I want to say is, unless you want to do or understand this, if you just join in the fun, don't come.

3. Big data application refers to the integration and application of big data technology to a specific big data collection to obtain valuable information. For different businesses in different fields and enterprises, or even the same business of different enterprises in the same field, the big data technology and big data information system adopted may be quite different due to different business requirements, data collection and analysis, and mining objectives. Only by insisting on the synchronous development of the trinity of combing objects, technologies and applications can we

Can fully realize the value of big data.

When your technology reaches the limit, it is also the limit of data. Big data is not how to define it, but how to use it. The biggest challenge is which technologies can make better use of data and how to apply big data. Compared with traditional databases, the rise of open source big data analysis tools such as Hadoop and the value of these unstructured data services.

Second, the types and value mining methods of big data

1, the types of big data can be roughly divided into three categories:

1) Traditional enterprise data: including customer data, traditional ERP data, inventory data and account data of CRM system.

2) Machine generated/sensor data: including CallDetail records, smart meters, industrial equipment sensors, equipment logs (usually digital exhaust), transaction data, etc.

3) Socialdata: including user behavior records, feedback data, etc. Social media platforms such as Twitter and Facebook.

2. There are four main methods for big data mining business value:

1) subdivide customer groups, and then customize special services for each group.

2) Simulate the real environment, explore new demands and improve the return on investment.

3) Strengthen departmental contact and improve the efficiency of the whole management chain and industrial chain.

4) Reduce service costs, find hidden clues and innovate products and services.

Third, the characteristics of big data.

The industry usually uses four V's (namely, volume, category, value and speed) to summarize the characteristics of big data. Specifically, big data has four basic characteristics:

1 is a huge amount of data.

A large amount of data refers to a large data set, which is generally around 10TB. However, in practical application, many enterprise users put multiple data sets together, which has formed a PB-level data volume. According to Baidu's data, its new homepage navigation needs to provide more than1.5pb (1Pb =1024tb) every day, and if printed, it will exceed 500 billion A4 sheets. It has been confirmed that up to now, the data volume of all printed matter produced by human beings is only 200PB.

2. There are various types of data.

There are many kinds of data, which come from various data sources, and the types and formats of data are increasingly rich, which has broken through the previously defined category of structured data, including semi-structured and unstructured data. Nowadays, data types are not only text, but also pictures, videos, audio, geographic information and other types of data, and personalized data accounts for an absolute majority.

3, the processing speed is fast.

In the case of huge amount of data, real-time data processing can also be realized. Data processing follows the funny law of 1 sec, and quickly obtains high-value information from all kinds of data.

4, it is high-value authenticity and low density.

The data is highly authentic. With people's interest in new data sources such as social data, enterprise content, transaction and application data, the limitations of traditional data sources have been broken, and enterprises increasingly need effective information power to ensure their authenticity and security. Take video as an example. An hour of video, in the process of uninterrupted monitoring, may only have one or two seconds of useful data.

Four: the role of big data

1, the processing and analysis of big data is becoming the node of the new generation of information technology integrated application.

Mobile Internet, Internet of Things, social networks, digital home, e-commerce and so on are the application forms of the new generation of information technology, and these applications constantly produce big data. Cloud computing provides a storage and computing platform for these massive and diverse big data. Through the management, processing, analysis and optimization of data from different sources, the results are fed back to the above applications, thus creating great economic and social value.

Big data has the energy to promote social change. But releasing this energy requires strict data governance, insightful data analysis and an environment to stimulate management innovation (Ramayya Krishnan, Dean of Hindes College of Carnegie Mellon University).

2. Big data is the new engine for the sustained and rapid growth of the information industry.

New technologies, new products, new services and new formats will emerge in the big data market. In the field of hardware and integrated equipment, big data will have an important impact on the chip and storage industry, and will also give birth to markets such as integrated data storage and processing servers and memory computing. In the field of software and services, big data will lead to the development of fast data processing and analysis, data mining technology and software products.

3. The use of big data will become a key factor to improve core competitiveness.

Decisions in all walks of life are driven by teasing business.

Transform data-driven fun. The analysis of big data allows retailers to grasp the market dynamics in real time and respond quickly; It can provide decision support for merchants to formulate more accurate and effective marketing strategies; Can help enterprises to provide consumers with more timely and personalized services; In the medical field, it can improve the accuracy of diagnosis and the effectiveness of drugs; In the public sector, big data has also begun to play an important role in promoting economic development and maintaining social stability.

4. In the era of big data, the methods and means of scientific research will undergo major changes.

For example, sampling survey is the basic research method of social science. In the era of big data, we can monitor and track the massive behavior data generated by research objects on the Internet in real time, conduct mining and analysis, reveal regular things, and put forward research conclusions and countermeasures.

Verb (abbreviation for verb) The commercial value of big data.

1. Segmentation of customer base

Funny big data can segment customer groups and then take unique actions for each group. Marketing and service for specific customer groups has always been the pursuit of businesses. The massive data of cloud storage and the analysis technology of combing big data places make it possible to segment consumers in real time and with high cost performance.

Step 2 simulate reality

Use funny big data to simulate the real situation, explore new needs and improve the return on investment. Nowadays, more and more products are equipped with sensors, and the popularity of cars and smart phones makes the data that can be collected explode. Social networks such as blogs, Twitter, Facebook and Weibo are also generating huge amounts of data.

Cloud computing and big data analysis technology enable businesses to store and analyze these data together with transaction behavior data in real time, which is very cost-effective. Trading process, product use and human behavior can all be digitized. The technology of teasing big data can integrate these data for data mining, so in some cases, we can judge which scheme is different under different variables through model simulation (such as different promotion schemes in different regions).

The return on investment is the highest.

3. Improve the return on investment.

Improve the sharing degree of combing big data achievements in relevant departments and improve the return on investment of the entire management chain and industrial chain. Departments with strong ability to sort out big data can share the results of big data with departments with weak ability to sort out big data through cloud computing, Internet and internal search engines, and help them create business value by sorting out big data.

4. Lease of data storage space

Both enterprises and individuals have the demand for massive information storage. Only by storing these data correctly can we further explore their potential value. Specifically, this business model can be subdivided into personal file storage and enterprise use.

There are two kinds of families. Mainly through the easy-to-use API, users can easily put all kinds of data objects in the cloud, and then charge according to the usage like water and electricity. At present, many companies have launched corresponding services, such as Asia.

Mei Sen, Netease, Nokia, etc. Operators have also launched corresponding services, such as China Mobile's Cai Yun service.

5. Manage customer relationships

The purpose of customer management application is to deeply analyze and understand customers from different angles according to their attributes (including natural attributes and behavioral attributes), so as to increase new customers, improve customer loyalty, reduce customer churn rate and increase customer consumption. For small and medium-sized customers, specialized CRM is obviously big and expensive. Many small and medium-sized enterprises use Fetion as their main CRM. For example, add old customers in Fetion Group and post new customers in the circle of friends in the group.

Product preview, special sales notice, complete pre-sales and after-sales service, etc.

6. Personalized and accurate recommendation

Within operators, it is common to recommend various services or applications according to users' preferences, such as app store software recommendation and IPTV video program recommendation.

After analyzing the algorithm, it can be extended to commercial services, and data mining technology can be used to help customers carry out precise marketing. Future profits can come from the share of customer value-added parts.

Take the daily spam message place as an example. Not all emails are spam places, because the recipients don't need them, so they are regarded as spam. After analyzing the user's behavior data, we can send the needed information to those who need it, and turn the spam messages into valuable information. In McDonald's in Japan, users download coupons on their mobile phones and then go to restaurants to pay with the mobile wallet of operator DoCoMo. Operators and McDonald's collect relevant consumption information, such as what they often buy.

Hamburg, which store to go to, how often to spend, and then accurately push coupons to users.

7. Data search

Data search is not a new application. With the advent of the era of teasing big data, people's demand for real-time and all-round search has become stronger and stronger. We need to be able to search various social networks, user behaviors and other data. Its commercial application value lies in linking real-time data processing with analysis and advertising, that is, real-time advertising business and social service of mobile advertising in applications.

The information of users' online behavior mastered by operators makes the obtained data more comprehensive and more commercial. Typical applications such as China Mobile's funny Pangu search website.

Six: the important impact of big data on the economy and society

1, which can promote the realization of huge economic benefits.

For example, the contribution to the growth of retail net profit in China, and the reduction of R&D and assembly costs of manufacturing products. It is estimated that in 20 13 years, global big data will directly and indirectly drive information technology expenditure to reach120 billion US dollars.

2. It can promote the improvement of social management level.

The application of big data in the field of public services can effectively promote the development of related work, improve the decision-making level, service efficiency and social management level of relevant departments, and generate great social value. By analyzing the traffic flow data collected in real time, many cities in Europe can guide drivers to choose the best route, thus improving urban traffic conditions.

3. Without high-performance analysis tools, the value of big data cannot be released.

We must keep a clear understanding of the application of big data, neither blindly believe its analysis results nor deny its important role because it is not completely accurate.

1) Due to various reasons, the data objects to be analyzed and processed will inevitably contain all kinds of wrong data and useless data, while the technologies such as data analysis and artificial intelligence, which are the core of big data technology, are not yet fully mature, so it is impossible to require the computer to complete the big data analysis and processing results to be completely accurate. For example, by analyzing the search content of hundreds of millions of users, Google can predict the outbreak of influenza faster than professional organizations, but this prediction is inaccurate many times due to the interference of useless information on Weibo.

2) It must be clearly positioned. The focus of the role and value of big data is to guide and stimulate the innovative thinking of big data users and assist decision-making. Simply put, when you deal with a problem, usually people can think of one method. Big data can provide ten reference methods, even if only three are feasible, it will triple the thinking of solving the problem.

Therefore, objectively understanding and giving play to the role of big data, without exaggerating or shrinking, is the premise of accurately understanding and applying big data.

Seven: Finally, the Beijing Universiade will give you a summary.

Regardless of whether the core value of big data is prediction or not, the decision-making model based on big data has brought profits and word of mouth to many enterprises.

1. From the value chain analysis of big data, there are three modes:

1) holding big data, but not making good use of it; Typical are financial institutions, telecommunications industry, government agencies and so on.

2) I don't have data, but I know how to help people with data use it; Typical IT consulting and service enterprises, such as Accenture, IBM and Oracle Bone Inscriptions.

3) There are both data and big data thinking; Typical ones are Google, Amazon, MasterCard, etc.

2. The most valuable things in the field of big data in the future are two things:

1) People with big data thinking can turn the potential value of big data into real benefits;

2) Business areas that have not been touched by big data. These are unexplored oil wells and gold mines, also known as the blue ocean.

Big data is a typical field where information technology and professional technology, information technology industry and various industries are closely integrated, with strong application demand and broad application prospects. In order to grasp the new opportunities brought by this emerging field, it is necessary to continuously track and study big data, continuously improve the cognition and understanding of big data, adhere to the synergy between technological innovation and application innovation, accelerate the development and utilization of big data in various fields of economy and society, and promote the development of big data in countries, industries and enterprises.

The application requirements and application level of data have entered a new stage.
