What is SQL

What is SQL - SQL stands for Structured Query Language. SQL or also often referred to as a query is a language used to access the database. SQL was first introduced in IBM in 1970 and an ISO and ANSII standard is set for SQL. This standard does not depend on the machine used (IBM, Microsoft or Oracle). Almost all database software knows or understands SQL. So, the SQL command on all database software is almost the same.
