Is the big case technique big data?

In this summer's hit TV series "The Longest Day in Chang 'an", Jing 'an Company selected Zhang Xiaojing to handle the case for them by means of a big case, and also hyped up various things by means of a big case. This big case technology sounds like the ancient version of big data, so is it big data after all?

Big data lies in discovering and understanding the content of information and the relationship between information. Prediction based on correlation analysis is the core of big data. "Big data" is not just a "big" data set; If it is a data set with sufficient scale and dimension, it can be used for some prediction, analysis and more valuable information extraction.

Predicting this, we have been doing it. The ancients predicted the weather by looking at the sky, and we decided what clothes to wear tomorrow by looking at the weather forecast. Fans asked Octopus to predict whether the team would win or lose, and countless investors wanted to know what the stock market would be like tomorrow.

What's the difference between forecasting and forecasting? Yes If a bear Haizi throws a steel shovel right above me, I'm sure it will hit me in the face, so I quickly avoid it. The gravity of the earth and the steel shovel that Xiong Haizi threw directly above me are the reasons, and hitting me in the face is the result. I make a prediction based on causality. The prediction of big data is based on relevance. By looking for the relationship between data to predict, it does not explain, does not explain "why", only answers "what".

It can be seen that the big case technology does not have enough data and is not analyzed by correlation, so it is not real big data.
