A large data
From the use of the database as the primary means of data management start, data generation mode of human society has gone through three stages, and it is a huge change in the way the data generated finally lead to big data.
1) operating systems stage.
Appears database makes data management complexity is greatly reduced, in actual use, the database system used by most operators, operating as a data management system, subsystem, such as supermarket sales records system, the bank's transaction system, hospital patients medical records.
The first amount of data in human society is the start of a big leap in the operating systems for wider use database. The main feature of this stage is to generate data is often accompanied by a certain degree of operational activities; and the data is recorded in a database, for example, a product sold in every store will have a corresponding sales records in the database. Such data generation mode is passive.
2) user-generated content stage.
Birth of the Internet to promote human society, the amount of data appear second great leap forward, but the real outbreak data produced in the era of Web 2.0, Web 2.0 and the most important sign is user-generated content. Such data in recent years has been showing explosive growth.
There are two main reasons for the following aspects. [Many beginners, the concept of big data is ambiguous, what big data is, what to do, when to learn, which is in accordance with what line to learn, learn where to complete the development, want to learn, I want to learn students are welcome to join big data learning qq group: 458 345 782, there are a lot of dry goods (zero-based combat and advanced classical) for everyone to share, and a senior lecturer at Tsinghua graduate of big data to you free lessons to share with the most current complete big data-end real practical learning process system]
Is a blog, microblogging and micro letter to Chu and now the rapid development of new social networks on behalf of such user-generated data willingness to be more intense.
Based smart phones, tablet PCs appear as the representative of new mobile devices, which are easy to carry, all-weather mobile devices to access the network makes way for people to express their opinions on the Internet more convenient. This phase of data generation mode is active.
3) perception systems stage.
A large amount of human social data of the third leap eventually led to the creation of large data, today we are at this stage. The fundamental reason is that the widespread use of leap-sensing system.
With the development of technology, people have the ability to create tiny sensors with processing functions, and start these devices are widely deployed in every corner of society, to monitor the functioning of the entire society through these devices. These devices would continuously produce new data, such data generation mode is automatic.
In simple terms, data generation experienced a passive, active and automatic three stages. These passive, active and automated data constitute the data source big data, but the most fundamental reason for which type of data is automatically generated big data.
The role of Big Data
Big Data Although conceived in information and communication technology, but its impact on social, economic, lives in no way limited to the technical level. More essentially, it provides us with a new way of looking at the world, that is the decision-making behavior it will be increasingly based on data analysis rather than as in the past with more experience and intuition. Specifically, the big data will have the following effect.
1) analysis of the large data processing is becoming the next generation of information technology applications fusion junction.
Mobile Internet, networking, social networking, digital home, e-commerce is the application form the next generation of information technology, these applications continue to produce big data.
These cloud mass, a large variety of computing platforms and data storage provides. Through the management of data from different sources, processing, analysis and optimization, the results back to these applications, will create huge economic and social value, big data has the energy of the birth of social change.
2) Big Data is the information industry sustained rapid growth of the new engine.
New technology for big data market, new products, new services, new formats will continue to emerge.
In the field of integrated hardware and devices, big data will chip storage industry have a major impact, also gave birth to the integration of data processing server storage, memory, calculation and other markets.
Software and services in the field of big data will lead to rapid data processing and analysis, data mining technology and software development products.
3) the use of big data will be a key factor to improve the core competitiveness.
All walks of life decision-making is shifting from a "business-driven" "data driven" to.
In business, the analysis of big data allows retailers the real-time grasp of market trends and make quick response, can provide decision support to develop more accurate and effective marketing strategies for businesses, can help companies to provide consumers with more timely and personalized service.
In the medical field, can improve the diagnostic accuracy and effectiveness of the drug.
In the public sector, big data have begun to play an important role in promoting economic development, maintaining social stability and other aspects.
4) the era of big data, methods and means of scientific research will be a significant change.
For example, a sample survey is a basic social science research methods, in the era of big data, the researchers through real-time monitoring, data tracking study mass behavior generated on the Internet, excavation analysis revealed the regularity of things, proposed conclusions and countermeasures.
