Structured Query Language or SQL is a programming language used to communicate with a database. It is mainly used to deal with the rational database. SQL is used to modify index structure and database tables. It was originally known as Structured Query English Language. Donald D. Chamberlin and Raymond F. Boyce developed to the language during 1970 at IBM. All rational databases use SQL as their normal database language. Examples of the rational database are SQL server, MS Access, and Oracle. A programming language that explains what you do not how the task is done is a declarative language and SQL is a declarative language. That is statements in SQL only ask what you want to insert or delete or retrieve from the database, not the way the same is to be done. This is why SQL is also called as query language since we can only use to ask query from the database using SQL. However, the language is as difficult and complex as much it is popular. The basic concepts of programming language and database management system are required when you choose SQL as a subject. The students must possess the complete knowledge and conceptual clarity about DBMS and RDBMS if he wants to master SQL. The knowledge of SQL can only be improved with practice. The course in SQL requires the students to complete and submit a number of practical and theoretical assignments.
