A database is a structured place where data is stored in an organized manner.
Instead of storing data in files or folders, databases store information in tables.
This makes data easy to search, update, and manage.
Every application that stores user data uses a database in the background.
A database is created to store related data together.
For example, a school database can store students, teachers, and classes.
Creating separate databases helps keep data organized and secure.
After creating a database, it must be selected before performing any operations.
SQL works only on the currently selected database.
If the database is not selected, tables and queries cannot be executed properly.
Large systems usually contain multiple databases.
Each database is created for a specific purpose or application.
This approach improves data management and avoids confusion between projects.
A database acts as the main container for tables.
Inside a database, data is stored in rows and columns using tables.
SQL commands are used to control databases and manage the data stored inside them.
