Introduction

On a daily, numerous users search for or visit various websites. However, a large number of users remain unaware that websites are split into two separate sections, the front-end, and the back-end. Unlike front-end development, which deals with the visual and interactive aspects of a website, back-end development focuses on building and maintaining server-side applications that facilitate the functionality and data storage of web applications. Essentially, the back-end serves as the hidden portion of a web application that is not visible to the user.

The back-end programming languages include Python, Java, PHP, Ruby, and more, as well as frameworks like Nodejs, Django, and Ruby on Rails. Back-end developers use these tools to create, maintain, and improve the functionality of web applications and sites.

Ruby is a widely-used, dynamic, high-level programming language that is commonly employed for back-end web development. It is popular for its versatility and can be used for building servers and processing data, as well as web scraping and crawling.

Proficiency in Back-End Frameworks

As a back-end developer, you can utilize specialized tools to create a website's architecture, and using frameworks can simplify the process. Furthermore, frameworks assist in enhancing the website's security and scalability. Hence, there are specific frameworks that back-end developers should contemplate using while developing a website.

• Nodejs

Node.js is a JavaScript runtime environment used for building server-side web applications. Its event-driven, non-blocking architecture makes it highly scalable and efficient. Node.js is built on the Chrome V8 JavaScript engine and is cross-platform, allowing it to work seamlessly on various operating systems such as Windows, Linux, and macOS.

• Django

Django, a high-level Python web framework, enables the development of complex, data-driven web applications. It promotes the creation of clean, reusable code and facilitates rapid development while adhering to the Model-View-Controller (MVC) architectural pattern. With Django, you get an Object-Relational Mapper (ORM) for database management, a powerful templating engine, and an admin interface for managing application data, among other built-in features.

• Ruby on Rails

Ruby on Rails, commonly referred to as just Rails, is a web application framework built on the Ruby programming language. It employs the Model-View-Controller (MVC) architecture, which provides developers with a standardized framework for constructing server-side web applications and APIs. In addition, it offers support for localization and includes libraries, scaffolding, and automated testing to streamline the development process.

Understanding of APIs

As a backend developer, APIs (Application Programming Interfaces) play a crucial role in building and maintaining software systems. APIs offer a standardized approach for applications to exchange data and functionality without requiring knowledge of the underlying code or structure of the other system. Backend developers rely on APIs to create connections between different applications, resulting in an enhanced user experience. JSON, SOAP, and REST are some of the most commonly used APIs among developers.

• JSON

JSON, which stands for JavaScript Object Notation, is a lightweight format for exchanging data and is commonly utilized as an API for back-end frameworks. JSON offers a straightforward, easily readable, and standardized approach for presenting data in a text format that can be smoothly transmitted between various systems.

• SOAP

SOAP (Simple Object Access Protocol) is a protocol that facilitates the exchange of structured data between different systems. It is commonly used as a back-end API for web services, providing a standardized approach for systems to communicate and exchange data consistently and dependably. SOAP messages are usually transmitted over HTTP, and the data is formatted in XML.

• REST

REST (Representational State Transfer) is an architectural style for developing web services and back-end APIs. It is based on a set of principles and constraints that ensure the interoperability, scalability, and maintainability of the API.

Version Control System

A Version Control System (VCS) is a software tool that enables developers to manage changes to their codebase over time. It is particularly valuable for teams of developers working on the same project, as it allows for collaboration and coordination. The VCS tracks every modification of code in a separate database. Here are some examples of popular version control systems:

• GitHub

GitHub is a community-driven open-source platform that provides support for developers. Its cloud-based infrastructure allows developers worldwide to view, collaborate, and contribute to code. With the aid of GitHub, individuals can offer assistance from any location to those in need.

• AWS Code Commit

AWS CodeCommit is another version control system hosted by Amazon. Users can store and manage data along with source code using this platform, which is highly secure and managed by the Git repository.

Data Structures and Algorithms

To excel as a back-end developer, having a strong foundation in Data Structures and Algorithms (DSA) is highly recommended. To prevent memory leaks and ensure efficient data handling, it is essential to retrieve and manage data proficiently. DSA is fundamental to programming, as it enables data organization, editing, and access. Therefore, before embarking on a career as a back-end developer, it is essential to master DSA, as it plays a vital role in optimizing and enhancing the efficiency of the code.

Knowledge About Servers

Important services are typically delivered through servers, making it the only system that cannot be turned off. Therefore, it is crucial to have a good understanding of how servers function. A server is a cloud-based system that stores all necessary data and provides other systems connected to the network with services such as file storage, database access, and security. The information on the server is used to retrieve and reorganize previously saved data. The most popular server management tools include Kubernetes, Docker, and others.

Problem-Solving

Back-end developers must possess strong problem-solving skills, as it is an essential skill for their role. They should be able to quickly identify and resolve issues to ensure that the system functions smoothly and meets the end-users requirements. By combining their technical knowledge and problem-solving abilities, they can create reliable and robust systems that cater to their users' needs.
