What is SQL?

Structured Query Language (SQL) is a specialized programming language designed specifically for managing and manipulating relational databases. It allows users to perform a variety of operations on the data stored within those databases, such as querying data, inserting new records, updating existing records, and deleting data. SQL provides a standardized way for users to interact with the database, enabling them to retrieve specific information through queries and to manage the overall structure of the database itself, including the creation and modification of tables and relationships between them.

The focus of SQL on relational databases distinguishes it from other programming languages used in different contexts. For instance, it is not a general-purpose programming language for developing web applications, nor is it a markup language for creating web pages. Additionally, it does not relate to user interface design. Therefore, understanding SQL is fundamental for anyone involved in data-driven tasks, as it equips them with the tools to effectively manage and utilize the data within relational databases.
