Structured Query Language – SQL

Structured Query Language, or SQL, is a standard programming language used to manage and manipulate databases. It is widely used in IT to store, retrieve, and organize data efficiently.

SQL allows users to perform various operations such as querying data, updating records, and controlling access within relational database management systems (RDBMS). Popular databases, such as MySQL, Microsoft SQL Server, PostgreSQL, and Oracle Database, all rely on SQL. Its standardized syntax makes it a foundational skill in data analysis, software development, and IT system administration.
