2021 IEEE 6th International Conference on Big Data Analytics (ICBDA)
Big Data overall architecture consists of three layers: data storage, data processing, and data analysis. Data storage layer stores complex types and mass data, the data processing layer realizes real-time processing of massive data, and only through the data analysis layer, smart, in-depth, and valuable information are got. When talking about big data, it comes to the first is 4V characteristics of big data, namely Volumes, Variety, Velocity , Veracity. Big data processing key technology generally includes: data acquisition, data preprocessing, data storage and data management, data analysis and mining, big show and application (big data retrieval, data visualization, big data applications, data security, etc.).
