What are the characteristics of big data?

The editor will share with you what are the characteristics of big data. I hope you will gain something after reading this article. Let's discuss it together.

Big data refers to the data set that can not be captured, managed and processed with conventional software tools within a certain period of time. It is a massive, high growth rate and diversified information asset that requires a new processing model to have stronger decision-making power, insight and process optimization ability. Features: mass, high speed, diversity, low value density, authenticity.

Big data (big data), IT industry term, refers to the data set that can not be captured, managed and processed with conventional software tools within a certain period of time. It is a massive, high growth rate and diversified information asset that requires a new processing model to have stronger decision-making power, insight and process optimization ability.

In the big data era, written by Victor Mayr-Schoenberg and Kenneth Cukeye, big data means that all data are analyzed instead of shortcuts such as random analysis (sampling). Big data's 5V characteristics (proposed by IBM):

Volume (massive): huge amount of data

Centralized storage / centralized computing has been unable to deal with the huge amount of data.

The amount of data is growing exponentially: sensors on earthquakes, logging and oil rigs produce more data in a month than all the movies in the world put together.

Sina Weibo has 250 million + users, peaking at hundreds of millions a day.

Variety (diversity): unstructured data diversity

Text / pictures / videos / documents, such as micro-seismic, electromagnetic and optical fiber distributed temperature monitoring (DTS).

Velocity (high speed): fast data growth

Large user base / large number of devices / real-time mass / exponential growth of data.

Value (low value density): value of data

Each rig has 40000 sensors, but usually only 10% of the data is used.

The investment of each deepwater drilling platform can reach $150m, and it is critical to make effective use of all the data, which is related to safety and optimized operation.

Vercity: the authenticity of data
