The role of big data is as follows:
1, the processing and analysis of big data is becoming the node of the new generation of information technology integrated application. Mobile Internet, digital home, Internet of Things, social network and e-commerce are the application forms of the new generation of information technology, and these applications constantly produce big data.
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.
3. The use of big data will become a key factor to improve core competitiveness. The decision-making of all walks of life pays more and more attention to the analysis of big data, which allows retailers to grasp the market dynamics in real time and respond quickly.
Big data:
Big data, or huge amount of data, means that the amount of data involved is so large that it can't be captured, managed, processed and sorted out within a reasonable time by current mainstream software tools to help enterprises make more active business decisions.
In The Age of Big Data, co-authored by Victor Meyer-Schoenberg and Kenneth Cookeye, big data means that all data are used for analysis and processing, and there is no shortcut to random analysis (sampling survey). Big data induction has five characteristics: volume (mass), speed (high speed), diversity (diversity), value (low value density) and authenticity.
The definition given by McKinsey Global Institute is that the scale of data sets far exceeds the capabilities of traditional database software tools in acquisition, storage, management and analysis, with four characteristics: massive data scale, rapid data flow, diverse data types and low value density.
