Full Form of SQL is Structured Query Language: SQL stands for the Structured query language. It’s typically pronounced as see-well. It’s a widely used programming language designed for operating with relational database Management System.
Initially, it was named as SEQUEL (Structured English question Language) designed to add, update or take away information from among a database. Later, it modified its name as Structured search language (SQL). SQL is originally primarily based upon relational algebra and Tuple relational Calculus. SQL was developed at IBM by Donald D. Chamberlin and Raymond F. Boyce within the early Nineteen Seventies.
According to Wikipedia:
SQL (Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). In comparison to older read/write APIs like ISAM or VSAM, SQL offers two main advantages: First, it introduced the concept of accessing many records with one single command, and second, it eliminates the need to specify how to reach a record, e.g.: with or without an index.
Originally based upon relational algebra and tuple relational calculus, SQL consists of a data definition language, data manipulation language, and data control language. The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements.
SQL was one of the first commercial languages for Edgar F. Codd’s relational model, as described in his influential 1970 paper, “A Relational Model of Data for Large Shared Data Banks”. Despite not entirely adhering to the relational model as described by Codd, it became the most widely used database language.
SQL may be a wide used programing language designed for working with RDBMS. Initially it had been named as SEQUEL (Structured English question Language), designed to add, update, or remove information within a database, or to control the data of the database. Later it had been modified to its name that we all know these days Structured query language. SQL is wide employed by several database software package systems together with MY SQL, Microsoft SQL Server and Oracle database.
