What is Django?

Django is software you can use to develop web applications quickly and efficiently. Most web applications have several common functions, like authentication, information retrieval from a database, and cookie management. Developers have to code similar functionality into every web app they write. Django makes their job easier by grouping the different functions into a large collection of reusable modules, called a web application framework. Developers use the Django web framework to organize and write their code more efficiently and significantly reduce web development time.

There are several web frameworks on the market. Django was written in the Python language, and it is one among many Python web frameworks. However, developers often prefer the Django web framework over others for the following reasons.

The Django framework is well organized and straightforward to install and learn, so you can get started within hours. Django designers created the framework to quickly implement any web architecture in code. It supports rapid development and clean, pragmatic design. You can write code in just a few lines because Django provides a ready-to-use structure for several common web development tasks, such as:

Django is a free and open-source Python project with an active community that reviews and maintains the software. A not-for-profit organization called the Django Software Foundation promotes and supports the use and maintenance of Django. It runs regular meetups, gatherings, and community events that encourage other developers to review and contribute to the Django project. The result is a high-quality, feature-rich web framework that is free to use.

Because of its popularity, the framework continues to evolve and has a strong support infrastructure. A large number of individuals and companies provide free and paid support for any development challenges you might face when you're using Django.

Any web application is made of two parts: server code and client code. The client or website visitor has a browser. When they type a URL into their browser, they send a request to the web server machine on which the web app is running. The server processes the request by using a database and sends information back to the client as a response. The client code displays the information to the visitor as a web page.

Django models act as the interface between the database and the server code. They are the single definitive source of information about your data. These data models contain the essential fields and operations you require to interact with your database. Django models thus convert your database tables into classes or objects in the Python code. This is called object-relational mapping.

Generally, each model maps to a single database table and has attributes that represent the database fields. If, for instance, your website comprises employee details it could be represented.
