WHAT IS SQL?

It is commonly used for operations such data querying, updating, adding, and removing in a database. It is a standard language for interfacing with relational database management systems (RDBMS). The main purpose of SQL is to query data from databases. SELECT queries can be used to extract certain data from one or more tables. Additionally, it is used to build and maintain a database's structure, which includes defining relationships between tables, setting constraints, and creating and modifying tables (CREATE TABLE, ALTER TABLE).  SQL is frequently used to communicate with databases and retrieve or update data in the backend of web applications.
