Big data technology refers to the application technology of big data, covering all kinds of big data platforms, big data index system and other big data application technology.
Big data is a collection of data that cannot be captured, managed, and processed within a certain timeframe with conventional software tools. It is a massive, high-growth and diverse information asset that requires new processing models to have stronger decision-making, insight discovery and process optimization capabilities.
With the advent of the cloud era, big data has attracted increasing attention. According to a team of analysts, big data is often used to describe the vast amount of unstructured and semi-structured data a company creates that would take too much time and money to download to a relational database for analysis.
Big data analytics is often associated with cloud computing because real-time analysis of large data sets requires frameworks like MapReduce to distribute work to dozens, hundreds or even thousands of computers.

Three dimensions of big data:
1. Theory, which is a necessary pathway to cognition and a baseline that is widely recognized and disseminated. Here from the definition of the characteristics of big data to understand the industry's overall portrayal and characterization of big data; from the discussion of the value of big data to y analyze the preciousness of big data; insight into the development trend of big data; from the privacy of big data, a special and important perspective to look at the long game between people and data.
2, technology, technology is the means to reflect the value of big data and the cornerstone of progress. Here respectively from the cloud computing, distributed processing technology, storage technology and perception technology development to illustrate the big data from the collection, processing, storage to the formation of the results of the whole process.
3, practice, practice is the ultimate value of big data embodiment. Here respectively from the Internet of big data, government big data, enterprise big data and personal big data four aspects to depict the big data has shown a beautiful scene and the blueprint will be realized.
