Introduction to Data Structures

Introduction

Data Structure is defined because the cluster of {data of | knowledge| of information} elements that provides an efficient method of storing and organizing data within the pc so it may be used with efficiency. Data Structures are wide used in nearly every side of computing i.e. OS, Compiler style, Artificial intelligence, Graphics and many more.

Data Structures are the most part of several computing algorithms as they enable the programmers to handle the info in an efficient method. It plays a vitle role in enhancing the performance of software or a program because the main function of the software is to store and retrieve the user's data as quick as possible.

Basic terminology

Data structures are the building blocks of any program or the software system. Selecting the acceptable data structure for a program is that the    most difficult task for an engineer. Following terminology is used as so much as data structures are involved

Data: data may be defined as an elementary worth or the collection of values, for example, student's name and its id are the info about the student.

Group Items: data things that have subordinate data things are referred to as cluster item, for example, the name of a student will have a first name and the last name.

Record: Record may be defined because of the collection of various data things, for example, if we tend to talk about the student entity, then its name, address, course, and marks may be sorted together to make the record for the student.

File: A File is a collection of various records of 1 type of entity, for example, if there are 60 employees within the class, and then there'll be twenty records within the connected file wherever every record contains the info about each employee.

Attribute and Entity: an entity represents the class of bound objects. It contains various attributes. Every attribute represents the particular property of that entity.

Field: Field could be a single elementary unit of information representing the attribute of an entity.

Need of data Structures

As applications are becoming complexes and the quantity of data is increasing day by day, there could arise the following problems:

Processor speed: To handle a very large amount of data, high-speed processing is required, but because the data is growing day by day to the billions of files per entity, the processor could fail to affect that much quantity of data.

Data Search: think about an inventory size of 106 things in a store, if our application needs to search for a particular item, it must traverse 106 items every time, leads to speed down the search method.

Multiple requests: If thousands of users are searching the data simultaneously on a web server, then there are the chances that a really large server may be failed throughout that process in order to resolve the on top of issues, data structures are used. Data is organized to make {a data |a knowledge| an information} structure in such the way that each one things aren't needed to be searched and needed data may be searched instantly.

Advantages of data Structures

Efficiency: efficiency of a program depends upon the selection of data structures. For example: suppose, we've got some data and that we need to perform the search for a particular record. In this case, if we organize our data in an array, we thought to search consecutive part by part. Hence, victimization array might not be terribly economical here. There are higher data structures which may build the search method economical like ordered array, binary search tree or hash tables.

Reusability: data structures are reusable, i.e. once we've got enforced a specific system, we will use it at the other place. Implementation of data structures may be compiled into libraries which may be used by completely different shoppers.

Abstraction: system is fixed by the ADT that provides a level of abstraction. The shopper program uses the info structure through interface solely, while not stepping into the implementation details.
