SQL, or Structured Query Language, is a programming language used to manage and manipulate relational databases. It consists of several basic commands that form the foundation of SQL operations. The most common commands include SELECT, which retrieves data from one or more tables; INSERT, which adds new records to a table; UPDATE, which modifies existing records; and DELETE, which removes records from a table. Additionally, there are commands such as CREATE TABLE, which creates a new table in a database, and ALTER TABLE, which modifies the structure of an existing table. These basic SQL commands, when combined and executed correctly, allow users to effectively interact with databases and retrieve, modify, or delete data.
