Structured Query Language (SQL)

Structured Query Language (SQL) is the cornerstone for interacting with relational database management systems. Used extensively in data management and retrieval, SQL enables you to manipulate and query data efficiently across diverse systems.

It supports various operations including querying data (SELECT), inserting new data (INSERT), updating existing data (UPDATE), and deleting data (DELETE). SQL is integral in defining and modifying data structures through commands like CREATE, DROP, and ALTER.

Its ability to handle structured data across applications makes it a foundational skill for database administrators, developers, and any professionals involved in data analysis or management.
