Differences and connections between big data and ordinary data

The essence of big data is how to acquire, process and analyze the data when it reaches a certain level. Other issues, such as how to build a data center and whether to adopt the form of data concentration, can be said to have little to do with the essence of big data. The data used by big data can be brought from a centralized place, and it is more likely to be distributed in multiple places or multiple places in one place.

It can be said that big data is a large collection of ordinary data.
