is the volume of the database large and the amount of concurrent data on the website large enough to be called Big Data?

An example is:

You bought a refrigerator in JD, the refrigerator at night, when you are worried about the refrigerator empty, a shop will send you a push to say beer 50 percent. (almost 50 characters)

At the very least, you have petabytes of data, and a lot of data is written every day, and you need to read that data often.

Data is large, the relationship between the data is very complex, the data contains a lot of information, the frequency of data update is high

Data flows continuously into the database (no matter what database, or even just storage). The data is then analyzed in a variety of scenarios, for example, a person's two-degree relationship.

Find the connection between seemingly unrelated data, that is, let the dead data have a soul ~

Store all things---analysis of all the things that are stored. Analysis results anything (past, present and future)

The big data is to summarize people's habits or behavior in a statistical way.
That's how I understand it.

Analyze the correlation between things with as many dimensions as possible and as comprehensive a large amount of data.

Big data people can't afford to play. Large storage capacity, complex analysis, relational Network + intelligent analysis.
