Although the acquisition end has a plurality of databases, if the mass data are effectively analyzed, the data from the front end are imported into a centralized large distributed database, and preprocessing of some data is performed;

s3: big data statistics and analysis

The statistics and analysis mainly uses a distributed database or a distributed computing cluster to perform common analysis and classification on mass data stored in the distributed database so as to meet the analysis requirements of most data;

s4: big data mining

Unlike the foregoing statistical and analytical processes, data mining generally has no preset theme, and is mainly performed on existing data based on various algorithms, so as to achieve a predictive effect, thereby meeting the requirements of some high-level data analysis.
