<\/a>Web Application:
\n<\/b><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

The applications which will provide services over the web are called web applications.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Eg: gmail.com, facebook.com,www.pythonpower.in<\/b> etc
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Every web application contains 2 main components<\/span><\/span><\/p>\n


<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\t\t\t1) Front-End<\/span><\/b><\/div>\n

2) Back-End
<\/b>
\n\t\t\t<\/span><\/p>\n
\n
\n

1) Front-End:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

.<\/b> It represents what user is seeing on the website
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>We can develop Front-End content by using the following technologies:
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

  HTML, JS, CSS, JQuery and BootStrap
\n<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

.<\/b> JQuery and Bootstrap are advanced front-end technologies, which are developed by
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

using HTML, CSS and JavaScript only.
\n<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

HTML:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>HyperText Markup Language<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>Every web application should contain HTML. i.e HTML is the mandatory technology for
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

 web development.It represents structure of web page
\n<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n

CSS:<\/b> <\/span>Cascading Style Sheets
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n
\n
\n
\n
\n

. <\/b>It is optional technology, still every web application contains CSS.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>The main objective of CSS is to add styles to the HTML Pages like colors, fonts, borders etc<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

\n
\n
\n

Java Script:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>It allows to add interactivity to the web application including programming logic.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>The main objective of Java Script is to add functionality to the HTML Pages. ie to add
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

 dynamic nature to the HTML Pages.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

HTML <\/span>\uf0e0 <\/span>Meant for Static Responses
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

HTML+JS <\/span>\uf0e0 <\/span>Meant for Dynamic Responses
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Eg 1: To display “Welcome to PYTHONPOWER<\/b>” response to the end user only HTML is
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

enough,b’z it is static response.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Eg 2: To display current server date and time to the end user, only HTML is not enough
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

we required to use some extra technology like JavaScript,JSP,ASP,PHP ,PYTHON etc as it is
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

dynamic response.<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

\n
\n
\n

Static Response vs Dynamic Response:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>If the response is not varied from time to time and person to person then it is considered
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

 as static response.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Eg: Login Page of Gmail
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Home Page of ICICI Bank
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>If the response is varied from time to time and person to person then it is considered as
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

 dynamic response.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Eg: Inbox Page of Gmail
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

Balance Page of ICICI Bank<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

\n
\n
\n

2) Back End:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

It is the technology used to decide what to show to the end user on the Front-End.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

ie Backend is responsible to generate required response to the end user,which is
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

displayed by the Front-End.
\n<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Back-End has 3 important components:
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

The Language like Java,Python etc
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

The Framework like DJango,Pyramid,Flask etc
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

The Database like SQLite,Oralce,MySQL etc
\n<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n
\n

. <\/b>For the Backend language Python is the best choice b’z of the following reasons:
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>Simple and easy to learn, libraries and concise code.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>For the Framework DJango is the best choice b’z it is Fast, Secure and Scalable. Django
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

  is the most popular web application framework for Python.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>DJango provides inbuilt database which is nothing but SQLite, which is the best choice
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

 for database.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

. <\/b>The following are various popular web applications which are developed by using
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

  Python and DJango
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

Top 5 Features of Django Framework<\/b>: <\/span><\/span><\/p>\n


<\/span><\/p>\n

\n
\n
\n

Django was invented to meet fast-moving newsroom deadlines, while satisfying the tough<\/span><\/span><\/p>\n<\/div>\n<\/div>\n

\n
\n

requirements of experienced Web developers.
\n<\/span><\/span><\/p>\n

The following are main important features of Django<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

1) Fast:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Django was designed to help developers take applications from concept to completion
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

as quickly as possible.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

2) Fully loaded:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Django includes dozens of extras we can use to handle common Web development
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

tasks. Django takes care of user authentication, content administration, site maps, RSS
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

feeds, and many more tasks.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n
\n

3) Security:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Django takes security seriously and helps developers avoid many common security
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

mistakes, such as SQL injection, cross-site scripting, cross-site request forgery and
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

clickjacking. Its user authentication system provides a secure way to manage user
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

accounts and passwords.<\/span><\/span><\/p>\n

\n
\n
\n
\n
\n
\n

4) Scalability:<\/b><\/span><\/span><\/p>\n<\/div>\n<\/div>\n

\n
\n

Some of the busiest sites on the planet use Django\u2019s ability to quickly and flexibly scale
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

to meet the heaviest traffic demands.
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

5) Versatile:
\n<\/b><\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Companies, organizations and governments have used Django to build all sorts of
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

things <\/span>\u2014 <\/span>from content management systems to social networks to scientific
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

computing platforms.
\n<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

Note:<\/b><\/span><\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n

1 )As Django is specially designed web application framework, the most commonly<\/span><\/span><\/p>\n

required activities will takes care automatically by Django and Hence Developer’s life
\n<\/span><\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

will be simplified and we can develop applications very easily.
\n<\/span><\/span><\/p>\n
