How does a database work?

A database is a structured collection of data that is organized, stored, and managed in a way that allows for efficient retrieval, modification, and deletion of data when needed. Databases work by utilizing a database management system (DBMS), which acts as an intermediary between the users and the actual data stored. The DBMS handles the creation, maintenance, and querying of the database, ensuring data integrity and security. Databases use tables to store data in rows and columns, with each column representing a specific attribute of the data. These tables are connected through relationships, allowing for efficient retrieval and linking of related information. To access data, users interact with the DBMS through a query language or graphical user interface, which translates user commands into instructions that the DBMS can understand. When a query is executed, the DBMS retrieves the relevant data from the database and returns the result to the user.
