Web Framework

A web framework provides a standard way to build and deploy web applications with coding architecture and a collection of libraries or tools that allow developers to create web applications more easily and efficiently.

Using a web framework, you can significantly reduce your coding time.

For example, if you want to build user management functionalities in your web applications from scratch, you need to spend long hours building code; however, when using a web framework, you can use pre-made code by simply importing the code for user-management functionalities.

There are different types of web frameworks, from frontend-focused and backend-focused frameworks to full-stack frameworks, which can be used for both frontend and backend.

The scope of functionalities of web frameworks can be very different. Many front-end frameworks can be just called libraries, depending on the definition.

For example, Bootstrap is one of the most popular front-end web frameworks. It provides HTML, CSS, and JavaScript-based design templates and quick styling tools (classes) for layout, components, and other design elements. Bootstrap is very useful for quick styling but cannot be used for backend-related functionalities such as user authentication or database management.

On the other hand, backend or full-stack web frameworks, including Django, can provide user management, database management, or security management functionalities.

Django

Django is a Python-based full-stack web framework. It is considered a full-stack web framework that provides front and backend functionalities. (Recently, Django has been becoming increasingly popular for backend functionalities, providing APIs to frontend frameworks such as React.js. We'll explain this later.

There are several benefits of using Django for web applications.

Here are some examples of benefits:

You'll be able to minimize your coding time. Following the Django framework, you can make a simple app within a day.
You'll be able to access a built-in admin interface as soon as you implement a model (database).
You'll be released from SQL coding. Django's Object-Relational Mapping (ORM) system allows developers to interact with databases using Python code instead of SQL queries.
You can build a secured app quickly. Django includes many security features, such as protection against cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks.
You can scale up your app quickly. Django is designed to be scalable, meaning it can handle large amounts of traffic and data.

If you are a beginner, you may need help understanding what we are discussing, but you'll gradually understand these benefits through this course.
