What is sql, and other method like authentication and authorisation.

Question

Accepted Answer

SQL is a programming language used for managing data in relational databases. Authentication verifies a user's identity, while authorization determines what actions they can perform.

SQL (Structured Query Language) is used to communicate with databases to perform tasks such as querying, updating, and deleting data.
Authentication is the process of verifying a user's identity, typically through credentials like usernames and passwords.
Authorization determines what actions a user is allowed to perform after they have been authenticated. This is usually based on roles or permissions assigned to the user.
Other methods of authentication and authorization include multi-factor authentication, biometrics, and role-based access control (RBAC).
