What are Data Structure?

 Data structure is particular way of storing and organising information in a computer system. So that it can be retrieved and used most productively.

      Data is a basic act representing think.

Main element of data structure .....

-Information  ->   Process of Data.

-Knowledge -> Meaningful Information.

-Intelligence ->Application of Knowledge   

APPLICATION OF DATA STRUCTURE

-Storage ->How to store our program.

-Retrival ->How to access data.

-Real world application.

Data struceture mainly specifies the following four things..

-Organization of data.

-Accessing methods.

-Degree of associativity.

-Processing alternatives for information.

Data structure are the building blocks of a program. And hence the selection of a particular data structure stresses on the following two things...

1. Data structure must be rich enough in structure to reflect the relationship existing between the data.

2. Structure should be simple so that we can process data effectively whenever required.

Algorithm + Data Structure =Program.

Data structure are important for the following reasons...

*Data structure are used in almost every program or software system.

* Specific data structures are essential ingredients of many  efficient algorithms, and make possible the management of huge amounts of data, such as large integrated collection of data base.

* Some programming language emphasize data structures, rather than algorithms, as the key organising factor in software design.
