What is sql

SQL (pronounced "ess-que-el") stands for Structured Query Language. It is used to communicate with the database. According to ANSI (American National Standards Institute), SQL is the standard language for relational database management systems. Statements written in SQL are used to perform tasks such as update data on a database, or retrieve data from database. Some of the common relational database management systems that use SQL are: Microsoft SQL Server, Access, Oracle, Sybase, Ingres, etc. Although most database systems use SQL, but most of them also have their own additional proprietary extensions that are generally only used on their system. However, standard SQL commands such as "Select", "Insert", "Update", "Delete", "Create", and "Drop" can be used to accomplish almost everything that one needs to do with a database. This tutorial provide you with the instruction on the basics of each of these commands as well as allow you to put them to practice using the SQL Interpreter.
