SQL stands for "Structured Query Language." It's a programming language used for managing and manipulating relational databases. The primary functions of SQL include inserting and updating data in databases, retrieving data from databases, and performing various operations on the data.
SQL provides a standardized way for applications to communicate with relational database management systems (RDBMS). Some common RDBMS include MySQL, PostgreSQL, Microsoft SQL Server, and Oracle Database.
The language allows users to define the structure of the data (using commands like CREATE TABLE), insert data into the database (using commands like INSERT), retrieve data from the database (using commands like SELECT), and update or delete data (using commands like UPDATE and DELETE).
In essence, SQL provides a set of commands that enable users to interact with databases, making it a crucial tool for anyone working with data storage and retrieval.
