What is big data?

What is big data?

"Big Data" in the last two years in the IT industry is a very popular word, and "internet thinking", the big data has begun to apply in various industries, in our country http://www.aliyun.com/zixun/aggregation/33721.html " >2014 held in the two sessions above, heard the most is the use of large data analysis and processing, then what is the big data, how to understand this concept? Let's take a look at it together.

1. Definition of large data

Large data, but also become a huge amount of information, that is, those included in the data volume is very large, large-scale to even through the human brain or even mainstream software tools, in the right and reasonable time to manage, process and dig out useful information, to make decisions to provide more active consultation.

2. Four features of large data

The real-time requirement is strong, the data stored in large amount of value, the data type is numerous, the data quantity is huge. There is a large number of data in almost every industry, but because of the numerous information and consulting complex, we have to search through tools, analysis, processing, induction and other scientific methodologies.

3. Large data collection

Now the development of science and technology and the promotion of the Internet into the Big Data era, in all walks of life output very large data volume, data units from the group began in bytes, KB, MB, GB, TB development to PB, EB, ZB, YB even BB, NB, db to measure. Data collection is no longer a technical study in the large data age, and the focus is on how to dig out valuable information in the face of so much data.

4. Large data mining and processing

Large data now have no way to use the human brain to calculate and predict, and some can not even use a single computer for data mining, so we must use a distributed computing architecture, through the cloud computing distributed processing, distributed database, cloud storage and virtualization technology, So in large data mining and processing is the need to apply cloud technology.

5. Application of Large data

Large data can be used in various sectors of the society, the collection of large data analysis and processing, effective use of data effectively. To give a very simple example, for example, in the cow's genes to find the genes related to cow production, this time we can first on the whole body of the cow gene scan, and then get the effective gene, but because the data collection is very large, this time need to use large data acquisition technology, Then, we analyze and compare them, and excavate the effective main genes.

6. Future development and significance of large data

In general, large data is a large, dynamic, 17812.html "> Sustainable data Mining, through the operation of a new system, tool model for data excavation, so as to obtain valuable new things." In the past, we may be only blinders to the vast data, so we do not understand the nature of things, and thus the wrong judgments made in scientific work, now the advent of the big data age, will be all the truth in front of us.
