Tables and databases are closely related concepts.
A database is a collection of organized and stored data that can be viewed as an electronic filing cabinet. It is used to store and manage large amounts of data and provide access and manipulation of this data. Databases are structured and can be designed and managed according to specific models and rules.
The table is one of the organizational forms of data in the database and the basic unit in the database. A table consists of rows and columns, with rows representing records or data items and columns representing attributes or fields of data. Each table has a unique name, and different columns and data types can be defined to store various data.
In a database, you can create multiple tables to represent different entities or relationships, and use rows in the tables to store specific data. Through the definition of table structure and the association between tables, complex data models and connections between data can be established.
To summarize, tables are the way data is stored in the database, and the database is the overall container and management system for data. Tables can be created, queried, updated, deleted and other operations through the functions provided by the database to meet user needs for data.
