SQL (Structured Query Language) is a programming language used to manage and manipulate relational databases. It is the standard language used for managing databases in the IT industry. SQL is used to perform tasks such as creating, modifying, and deleting databases, tables, and records; querying data from databases; and managing users and permissions.
SQL is used by developers, data analysts, and database administrators. It allows users to create, store, retrieve, and manipulate data in relational databases. SQL queries are used to extract data from a database based on specific criteria or conditions. SQL statements are executed by a database management system (DBMS) such as MySQL, Oracle, or SQL Server.
Some common SQL commands include SELECT (to query data from a table), INSERT (to add data to a table), UPDATE (to modify data in a table), and DELETE (to remove data from a table). SQL also allows for the use of conditions, such as WHERE, to filter data based on specific criteria, as well as the use of functions to manipulate and transform data.
SQL is a powerful tool for managing and manipulating large datasets. It is widely used in industries such as finance, healthcare, and e-commerce to store and manage data. With the increasing importance of data in the modern world, SQL skills are highly valued by employers.
