A database is a warehouse that organizes, stores and manages data according to the data structure. It is a collection of organized, shareable and uniformly managed large amounts of data stored in a computer for a long time.

A database is a collection of data stored together in a certain way, shared with multiple users, with as little redundancy as possible, and independent of the application. It can be regarded as an electronic filing cabinet-a place where electronic files are stored. Users can add, query, update, delete and other operations on the data in the file.
