What is SQL? Structured Query Language is a computer language that we use to interact with a relational database.SQL is a tool for organizing, managing, and retrieving archived data from a computer database. The original name was given by IBM as Structured English Query Language, abbreviated by the acronym SEQUEL. When data needs to be retrieved from a database, SQL is used to make the request. The DBMS processes the SQL query retrieves the requested data and returns it to us. Rather, SQL statements describe how a collection of data should be organized or what data should be extracted or added to the database. In common usage, SQL encompasses DDL and DML commands for create, updates, modified or other operations on database structure.
