Web Application

If you are creating the web development or full stack development then django is one of the most popular tool will help you.by learning this django you can make your businesses to the digital presence.

In today era , we are leading two life's one is real-offline life and other one is online life mostly we depend on online life. Suppose in a scenario if we need to buy something from shop we have the digital presence of that shop products then knowing the requirement details of the product which we want to buy from that particular shop then we purchase it from the house itself.so all the business have the digital presence and how this digital presence will began by creating the " WEBSITE ".

The Person who help the enabled the creating the website for business/company we called them as Web developer who are creating the website.

Normal people called it as "Website" but the persons who are coming from the IT background called it as " Web Application "

if we want to create a web application by using python or java programming languages but this languages are just requirement but it is not the full requirement only partially we are using this programming languages to create web application other technologies are also needed because a web application is a application which can be visualize in 3 different layers.

now, what are this 3 layers means

1. The first layer is layer that we technically called as FRONTEND
2. The second layer we technically called as BACKEND
3. Of course , the first and second layers are useless without this layer that is DATA BASE

let us brief on this 3 layers of web application

Front end :- In simple words what we or user can see on the screen

suppose in a scenario if we open a amazon what we see in page that's all products details by this that details we interact with that product .

Every web application as a unique front end. if you want to create a frontend there is some code in the background and that code may not written in programming languages like python or java..etc there are few technologies which have been tailor made for this purpose and what are that technologies ?

let us discuss

1. html
2. css
3. java script

and of course there is one frame work which is combination of above three that is Bootstrap framework.

Backend :- This layer where hard core programming happen . where we write the code in python , java programming languages. Obviously for backend what we require is a programming languages such as python and django.

Database :- It is important layer. The approach is different from above two layers and technology & language require is also different from that two layers. The language which will learn to take care of data base is "sql (Structured Query Language ) ".

If you want to access a web application such as myntra , amazon ..etc what should we want to do means via through internet we send our request to the server the moment when send the request the server execute the application and send the responses through the user via internet .

suppose in a scenario in real time we searching one plus mobile phones in the amazon via internet and based on our request the server provide all manufacturing mobiles by oneplus.
