 Notations for Algorithms

We need a notation to represent algorithms. There are mainly three different notations for representing algorithms.
•
A programming language is a notation for expressing algorithms to be executed by computers.
•
Pseudo code is a notation similar to programming languages. Algorithms expressed in pseudo code are not intended to be executed by computers, but for communication among people.
•
Flowchart is a diagrammatic notation for representing algorithms

Introduction to SQL

Th e Structured Query Language (SQL) is a standard programming language to access and manipulate databases. SQL allows the user to  reate, retrieve, alter, and transfer information
among databases. It is a language designed for managing and accessing data in a Relational
Data Base Management System (RDBMS).

Th ere are many versions of SQL. Th e original version was developed at IBM’s Research centre and originally called as Sequel in early 1970’s. Later the language was changed to SQL.

In 1986, ANSI (American National Standard Institute) published an SQL standard that was
updated again in 1992, the latest SQL was released in 2008 and named as SQL 2008.
