 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.

Part 3 || Specification and Abstraction || 11 Std || Computer Science

 

       An algorithm is a sequence of instructions to accomplish a task or solve a problem. An instruction describes an action. When the instructions are executed, a process evolves, which accomplishes the intended task or solves the given problem. We can compare an algorithm to a recipe, and the resulting process to cooking.

         We are interested in executing our algorithms in a computer. A computer can only execute instructions in a programming language. Instructions of a computer are also known as statements.Therefore, ultimately, algorithms must be expressed using statements of a programming language.

 Introduction

Internet Protocol (IP) is the principle of the communications protocol in the Internet protocols for layering on datagram across boundaries of other networks. The main function is to allows Internet working and boost up the Internet. Internet protocol (IP) will deliver packets from the source host and it will deliver to the destination host via through an IP address in the packets header. Vint Cerf and Bob Kahnin in 1974 introduced IP connection less datagram service was in the transmission control program. 

 

Now the IP is referred as TCP/IP Transmission Control Protocol/Internet Protocol.

Relational Algebra in DBMS

What is Relational Algebra?

Relational Algebra, was first created by Edgar F Codd while at IBM. It was used for modeling the data stored in relational databases and defining queries on it.

Relational Algebra is a procedural query language used to query the database tables using SQL. Relational algebra operations are performed recursively on a relation (table) to yield an output. The output of these operations is a new relation, which might be formed by one or more input relations. Relational Algebra is divided into various
groups

SELECT ( symbol : ó)

PROJECT ( symbol : Ð)
