What is Backend Development?

Backend development involves server-side functions that facilitate user actions like making payments and checking out on websites like Amazon. The process involves the server, database, and application logic implemented by backend developers. It sends and receives data and works invisibly to display information on the front end. Backend developers handle everything behind the scenes, from databases to servers to API creation and data architecture. Various tools, languages, and technologies are used to accomplish these tasks, such as MongoDB, Oracle, MySQL, and SQL servers for CRUD operations. They serve the data back to the client-side of the application.

Backend Technologies for Web Development

Backend technologies are crucial for web development as they form the foundation of software creation. Specialized backend developers are required for the website or application to function well, be responsive and fast. With the exponential growth of backend technologies, it’s essential to choose the appropriate technology for your project. The benefits of backend technologies include task automation, developer productivity enhancement, simplified development processes, quicker development, improved product quality, scalability and robustness, and enhanced security and integration.

  • Django is a scalable framework that allows apps to switch from small to large-scale projects quickly and efficiently.
  • Django provides helper modules and libraries that developers can use to handle common web development tasks like user authentication, site maps, RSS feeds, and content administration.

Code:
“`
# import Django
import django

# check Django version
print(django.get_version())
“`

Spring Boot: A Framework for Java-based Web Development
