SQL

Structured Query Language (SQL) is a programming language designed for managing and manipulating data in relational databases. It enables users to execute various operations such as querying, updating, organizing data, defining the database schema, and overseeing user permissions.

SQL commands serve as the means to interact with a database and are generally divided into five primary categories based on their purpose, allowing users to define, query, manipulate, and manage data effectively.

Following best practices in SQL is vital for creating efficient, secure, and maintainable code. These practices help maintain data integrity, enhance query performance, and safeguard against common security threats, resulting in more reliable and scalable database applications.

The main distinction between SQL and NoSQL databases pertains to their data organization and scalability capabilities.

SQL serves as the standard method for handling data in relational databases, focusing on querying, manipulating, and defining data structures. It also plays a key role in managing user access, making it fundamental to data management.
