What is Big Data?
Big data, or big data, refers to the amount of data involved that is so large that it cannot be captured, managed, processed, and organized into a collection of information to help enterprises make business decisions through mainstream software tools in a reasonable time. The earliest reference to the term big data can be traced back to Apacheorg's open source project Nutc. Big data is used to describe large data sets that need to be batched or analyzed at the same time to update a web search index.
Big data can be divided into big data technology, big data engineering, big data science, and big data application. There are four levels of technical characteristics: First, the volume of data is huge. From the TB level, jump to the PB level;Second, there are many types of data. Such as web logs, geolocation information, and so on. Third, the value density is low and the commercial value is high. In the case of continuous monitoring, for example, the data that may be useful is only one or two seconds. Fourth, the processing speed is fast. The last point of the one-second rule is fundamentally different from traditional data mining techniques.
The strategic significance of big data technology is not to grasp the huge amount of data information, but to professionalize the processing of this meaningful data. In other words, if big data is compared to an industry, then the key to the profitability of this industry is to improve the "processing ability" of data, and realize the "value-added" of data through "processing". Compared with traditional data warehouse applications, big data analysis has the characteristics of large data volume and complex query and analysis. Big data technology is widely used in retail, healthcare, finance, education, agriculture and other fields.
