Structured Query Language (SQL) is a specialized programming language designed for managing and manipulating data stored in relational databases. It allows users to store, manipulate, and retrieve data efficiently in databases like MySQL, SQL Server, Oracle, and more.

Key Features and Capabilities

SQL can perform a wide range of operations on databases, including:

• Executing queries to retrieve data.

• Inserting, updating, and deleting records.

• Creating new databases and tables.

• Creating stored procedures and views.

• Setting permissions on tables, procedures, and views.

Basic SQL Commands

SQL commands are categorized into several types:

1. Data Definition Language (DDL): Commands like CREATE, ALTER, and DROP to define and modify database structures.

2. Data Manipulation Language (DML): Commands like SELECT, INSERT, UPDATE, and DELETE to manipulate data.

3. Data Query Language (DQL): Primarily the SELECT command to query data.

4. Data Control Language (DCL): Commands like GRANT and REVOKE to control access to data.

5. Transaction Control Language (TCL): Commands like COMMIT and ROLLBACK to manage transactions.
