The Beginner’s Guide to Python Back-End Development

posted in: Uncategorized | 0

With experience or continued education, web developers can advance into computer systems management positions. Web development refers to the construction of websites and online applications. The field can also encompass web design, programming, website maintenance, security, and database management. The discipline brings together front-end and back-end development, which deal with client-facing and server-side development. Phoenix is a modern web framework written in Elixir, a high-performance and scalable programming language. It is designed to make building and deploying web applications easier and faster.

After the website goes live, back-end developers maintain and upgrade the system and its components as needed. In the computer world, the “backend” refers to any part of a website or software program that users do not see. It contrasts with the frontend, which refers to a program’s or website’s user interface. In programming terminology, the backend is the “data access layer,” while the frontend is the “presentation layer.” Now you hopefully have a good idea of the differences between the frontend and backend, and how they work together to create functional, user-friendly websites.

Java is another general-purpose programming language often used in the back-end of application development. It was built to be deployable across a wide range of environments and is flexible enough to support complex, high-performing software projects. It contains behind-the-scene activities that occur when performing any action on a website. It can be an account login or making a purchase from an online store. Code written by back-end developers helps browsers to communicate with database information.

  • Using the same language will make your code cleaner and more consistent.
  • The back-end is the code that runs on the server, that receives requests from the clients, and contains the logic to send the appropriate data back to the client.
  • CareerFoundry is an online school for people looking to switch to a rewarding career in tech.
  • Back-end developers are required to have technical expertise, analytical thinking, and excellent collaboration skills.
  • You get to learn about the most useful backend technologies, like MongoDB, and RabbitMQ.

A framework’s main objective is to standardize and simplify the development process by providing tools, libraries, and components that can be reused when developing web applications. In WordPress, the backend is the administration area of the website that can only be accessed by logged in users. Here, the site owner and their team can create content, install plugins, manage design settings, and more.

What is frontend development?

While server-side is among the most important components of a website, you should know that the server cannot initiate any responses without corresponding requests. Therefore, server-side serves as a secondary element in constructing a website, and it requires a proper incoming request to gather and send the data back to the frontend. Databases contain all the information ever received for any website or application, and these are hubs of broken-down pieces of information that are later used for various purposes.

Kotlin’s popularity among developers stems from its straightforward syntax and extensive features. Kotlin has a compact codebase that makes it a stable and consistent language for code development. You can easily detect codes at compile time which can be resolved before running the code. Python is a programming language that has endeared itself to many professionals. Data scientists, software engineers, machine-learning experts, and hackers love Python because of its flexibility, adaptability, and object-oriented features. Using JavaScript, Node.js makes it easy to send and sync data between the server and client sides.

Data Skills That Will Make You Better At Your Job

You’ll be in charge of implementing measures like user authentication, data encryption, and protection against common security vulnerabilities. For example, you might set up two-factor authentication to enhance user account security and prevent unauthorized access to sensitive financial data in a banking application. Here, you will learn Node.js and build web applications using the Express framework. If you want to start learning backend development, learn with freeCodeCamp’s Relational Database Course. Backend developers are in charge of the logic behind web applications and making the frontend function optimally.

So far, what you have is an example of a static website—its content doesn’t really change much. For static sites, all the necessary information that determines what’s on the web page is in the frontend code itself. So you decide to open an online store where people can shop and place orders anytime. This means your site will now have to store information about products, purchases, user profiles, credit cards, and more.

The back-end is the code that runs on the server, that receives requests from the clients, and contains the logic to send the appropriate data back to the client. The back-end also includes the database, which will persistently store all of the data for the application. This article focuses on the hardware and software on the server-side that make this possible.

If it starts sending more responses for a single request, it will end up throwing errors, and your website will not work properly. By doing this, you’re enabling an architecture that can be highly scaled. A database-operation intensive application could have an optimized solution for databases. And a heavy traffic bound site should have a good CDN mechanism to offload static assets, and so on. And the best way to do something comes out of necessity or interest.

Learn back-end development by writing real code

Convention over Configuration – Configuration files are not utilized by Ruby on Rails as it provides dynamic runtime extensions, reflections, and conventions. It follows a “Convention over Configuration” approach for automatically assigning value without requiring user intervention. Multiple configuration files are utilized by software systems like Java web application frameworks, with each having multiple settings. Convention raises productivity as users are not required to assign time for config file setup.

Besides backend programming languages, backend frameworks and libraries are used to provide extra functionality to create web applications. Back-end development means working on server-side software, which focuses on everything you can’t see on a website. Back-end developers ensure the website performs correctly, focusing on databases, back-end logic, application programming interface (APIs), architecture, and servers. They use code that helps browsers communicate with databases, store, understand, and delete data. Front-end developers build and maintain the front-end of websites and applications, the interface that users view, click, etc.
