Introduction to the Structure Query Language(SQL):

      Structured Query Language is the language of database. SQL (Structured Query Language) is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS).

• Structure Query Language and commonly pronounced as "SEQUEL" (Structured English Query Language).
• Dr. E.F Codd published the paper on relational database model in june 1970. IBM Corporation, Inc.
• SEQUEL later become SQL.
• It allows the user to communicate as the server.
• It is easy to learn and use.
• It is functionally complete, by allowing the use to define, retrieve and manipulate the data.
• Although most database systems use SQL, most of them also have their own additional proprietary extensions that are usually only used on their system. However, the 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.
