Structured Query Language (SQL) is a programming language used to manage and manipulate data in relational database management systems (RDBMS). SQL is a standard language that is used by many different RDBMS, including MySQL, Oracle, and Microsoft SQL Server.
SQL is used to create, modify, and query databases. It allows users to perform a wide range of operations on the data stored in a database, including inserting, updating, and deleting records; creating and modifying database structures; and querying data using complex criteria.
SQL is a powerful and flexible language that allows users to specify exactly what data they want to retrieve or modify. It also provides a range of functions and operators that can be used to manipulate data in sophisticated ways. For example, users can use SQL to perform calculations, join data from multiple tables, and group data by specific criteria.
SQL is used in a wide variety of applications and industries, including business, finance, healthcare, and government. It is a crucial tool for managing and organizing large amounts of data, and is an essential skill for database administrators, data analysts, and other professionals who work with data.
