The basic characteristics of the database are: unstructured data, data independence, small data redundancy, easy expansion, unified management and control. The database uses a complex data model to represent the data structure, and the database management system is used to manage and control the database to ensure the security and integrity of the database.

A database is a warehouse where data is stored. It has a large storage space and can store millions, tens of millions and hundreds of millions of pieces of data.
