What is Back-End Development?

Back-end development refers to the part of a website or application that you don’t see, which works behind the scenes to make everything function properly. It handles the communication between the database (where information is stored) and the browser (where you see and interact with the website).

In other words, it focuses on ensuring that the front-end elements of a web application can function seamlessly. The main focus areas of back-end development are:

• Server: The hardware or software that provides services to other computers in the network. For instance, web servers host websites and serve them to users who request them via browsers.

• Database: The organized collection of data, generally stored and accessed electronically. Databases store everything from user information to transaction records, which the application needs to access and manipulate.

• Application logic: The code that defines the behavior and logic of an application. This includes everything from processing user inputs to performing calculations and making decisions based on the data.

For example, when you log into a website, the back-end code checks the database for your credentials (username and password) and, if correct, retrieves and returns the correct user data to the front end. It then displays your personalized content.

Who is a Back-End Developer?

A back-end developer is responsible for server-side web application logic and integrating the work done by front-end developers.

Back-end developers create web services and APIs (tools that allow different software components to communicate) that front-end and mobile app developers use to build their parts of the application. Currently the demand for web developers (including back-end specialists) is expected to grow by 16% between 2022 and 2032, according to the U.S. Bureau of Labor Statistics. 

This number is higher than in many other sectors, reflecting the bright prospects of building a career in this field. Looking to become a web developer? Get started with Mimo—a flexible platform that helps you master coding and build a real-world portfolio.
