SQL

SQL (Structured Query Language) is a programming language used to manage relational databases. SQL is used to create, modify, and query databases, and is the standard language used for communicating with most relational database management systems (RDBMS). SQL is used for a wide range of applications, from managing large-scale enterprise databases to creating simple databases for small businesses or personal use. Some common uses of SQL include retrieving and manipulating data, creating and modifying database schemas, and administering database security and permissions. SQL uses a variety of statements, such as SELECT, INSERT, UPDATE, and DELETE, to manipulate data in a database. These statements are used to create, modify, and query data stored in tables, and can be used to perform complex operations such as aggregations, joins, and subqueries. SQL is a highly versatile language and can be used with a wide range of database management systems, including MySQL, Oracle, Microsoft SQL Server, PostgreSQL, and SQLite, among others. Its standardized syntax and broad usage make it a valuable skill for data analysts, database administrators, and software developers.
