Full Form of SQL

What is SQL?

SQL or Structured Query Language is a program created and formulated in the Relational Database Management System to handle structured data. Modifying or removing data from inside the database, SQL has initially named a SEQUEL(Structured English Query Language developed addition). With time, this name changed and became SQL.

Structure Query Language(SQL) is a database query language used for storing and managing data in Relational DBMS. SQL was the first commercial language introduced for E.F Codd's Relational model of database. Today almost all RDBMS(MySql, Oracle, Infomix, Sybase, MS Access) use SQL as the standard database query language. SQL is used to perform all types of data operations in RDBMS.

SQL: History

• Based on Relational Algebra and Tuple Relational Calculus, SQL was developed from the beginning.
• Raymond F. Boyce and Donald D. Chamberlin in the initial 1970s, at IBM, developed and produced SQL.
• The main reason to develop SQL was to run and retrieve information contained in IBM’s actual quasi-relational database management system.

SQL: Applications

• In gathering details.
• Operating on analytical queries
• To compose the Scripts for Data Integration
• To modify the mark designs and the database table.

SQL: Benefits

• SQL makes it easy to manage data structures.
• ISO & ANSI use SQL databases that use guidelines that are well described and long-established.
• SQL is seen in operating laptops, systems, servers and even a few smartphones inside the software.
• As it is an interactive domain language, SQL can be used to exchange and share information with the databases, and to address the complex questions in seconds.
• Users can create multiple views of the structure of the database by the SQL language as well as the databases for various individuals.

SQL: Limitations

• As it has a complex interface, SQL is difficult for some people to access.
• Due to the invisible business rules in SQL, the programmers using SQL do not have full command over the database.
• To guarantee vendor lock-in, many of the databases change from proprietary enhancements to standard SQL.
• Some programmers have trouble accessing different models of SQL due to high operating costs.
