What is Big Data? What are the characteristics of big data?
- Volume: Big data starts with a unit of measurement of at least P (1,000 T), E (1,000,000,000 T), or Z (1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000).
- Variety: Including web logs, audio, video, images, geolocation information, and so on, multiple types of data place higher demands on data processing capabilities.
- Low value density (Value): With the widespread use of the Internet of Things, information perception is ubiquitous, and there is a huge amount of information, but the value density is low, so how to more quickly complete the value of the data through powerful machine algorithms to "purify" the data is a problem that needs to be solved in the era of big data.
- Fast processing speed, high timeliness requirements (Velocity): this is the most significant feature of big data differentiated from traditional data mining.
