SQL, standing for Structured Query Language, is the standard language for interacting with relational database management systems (RDBMS). It enables users to access, manage, and manipulate data stored in databases. Its importance stems from its widespread use in various industries, from small businesses to large corporations, for data analysis, reporting, and application development.

1.1. What Is SQL Used For?

SQL is a versatile tool with numerous applications:

Data Retrieval: Extracting specific information from databases using queries.
Data Modification: Updating, inserting, or deleting data within databases.
Schema Definition: Creating and modifying database structures, such as tables and indexes.
Access Control: Managing user permissions and security settings.
Reporting and Analytics: Generating reports and performing data analysis to gain insights.

SQL operates on a variety of platforms, including Windows, Linux, and macOS, and is compatible with various programming languages, making it a flexible choice for developers and data professionals. SQL’s design allows users, regardless of their coding skills, to perform data queries using simple keywords like “SELECT”, “UPDATE”, or “DELETE”.

1.2. Popular Relational Database Management Systems (RDBMS) Using SQL

Several RDBMS utilize SQL as their primary query language:

RDBMS	Description
MySQL	An open-source RDBMS widely used for web applications.
