The relationship between big data and database

1. data storage: both big data and databases involve data storage. Databases store data in tables in a structured way, while big data can include structured, semi-structured and unstructured data, which can be stored by various storage technologies, such as distributed file system and NoSQL database.

2. Data management: The database provides data management functions, including data addition, modification, deletion and query. Big data needs to use different tools and technologies to manage and process large-scale and diverse data, such as distributed computing, data mining and machine learning.

3. Data analysis: The database can be used for data analysis and query, but for big data, the traditional database system cannot meet the requirements of processing large-scale data. Big data needs to use distributed computing and parallel processing technology to improve the speed and efficiency of data processing, and can carry out complex data analysis and mining.
