What is SQL?
SQL (Structured Query Language) is a programming language designed for managing relational databases. It allows users to perform tasks such as creating and modifying database structures, inserting, updating, and deleting data, and retrieving data from databases. SQL is widely used in businesses and organizations to manage large amounts of data efficiently and effectively.
SQL consists of various commands, including SELECT, INSERT, UPDATE, DELETE, CREATE, and DROP. These commands are used to perform different tasks on databases. For example, the SELECT command is used to retrieve data from a database, the INSERT command is used to add new data to a database, and the UPDATE command is used to modify existing data in a database.
SQL is used by a variety of relational database management systems (RDBMS), such as MySQL, Oracle, Microsoft SQL Server, and PostgreSQL. These systems provide tools and interfaces for users to interact with SQL and perform various database-related tasks.
