Building a dynamic website involves developing the front and back end. While the front end involves building the widgets, as well as everything you see when you view the website on a browser, the back end deals with those things which you can't see.
Back-end development means using programming languages like Python, PHP or Java to develop the server side of a website.
It is likely that you are already familiar with some of the programming languages that exist, since there are so many. This article looks specifically at the top 6 back-end languages and their features.
- Back-end programming languages are computer languages with special syntaxes used to develop the server side of a website or mobile app.
- Server-side or back-end development is building the server, database, and application programming interfaces (APIs) that power a website from behind the scene.
- A server-side developer is an expert that uses one of these programming languages to develop the back end of a web or mobile app.
What Is Back-End Development?
Server-side development involves building the server-side logic, architecture, databases, application programming interface (APIs) and servers that power a website.
To understand the back end, you need to know more about the front or client side. The client side of a website is everything a user interacts with. It is made up of elements such as the navigation menu, buttons, contact forms, and sidebars. The front-end of a website encompasses everything you can see and interact with.
But these element are not the only part of making a website dynamic. A dynamic website displays different content for each user based on the data retrieved from the database.
For example, an e-commerce website will display different shipping and billing information for various users, based on the data stored and retrieved from the website's database.
For that to happen, the front end must interact with the back end to display specific content for each user. The server and the database are the back-end systems that support the front end; they make the website dynamic and facilitate user engagement.
So, back-end development is the process of building the server, database and APIs that make you interact with the client side of a website.
What Is a Back-End Developer?
A back-end developer is an expert that builds and maintains the mechanisms that power a website from behind the scene.
Those mechanisms include the database that stores information, the server that keeps the site or app online and the various APIs that enhance the system's functionalities.
Unlike their front-end counterparts, which focus on everything you see on a site, server-side developers store data in the database, security and other functions, which you cannot see.
As part of a team, back-end programmers collaborate with client-side developers, product managers, software architectures and site testers to build the structure of a mobile app or website.
They must be familiar with tools and frameworks like Python, Java, Ruby, NodeJS, Laravel, etc., to develop a back end that performs quickly and responsively to the user's requests.
Below are some of the responsibilities of a back-end programmer.
- Build and maintain a website or app. Back-end developers' primary role is to use various tools, frameworks and programming languages to determine how best to build user-friendly websites that load fast. This role requires an understanding of cross-platform functionality and compatibility.
- Perform quality assurance testing. Server-side programmers oversee software testing to optimise the user interface and experience, ensuring the site displays on all devices and browsers.
- Write code. Programmers must write clean, easily maintainable code and work with front-end developers to transfer data to the client.
- Debugging and troubleshooting. Back-end developers must be able to debug code to eliminate errors and improve performance.
What Are Back-End Languages?
Back-end languages are the computer languages, with unique syntax, that programmers use to build the system that powers a web app. There are many server-side languages developers can use.
Below are just a few:
These programming languages make it easy for developers to connect a website to the database and server, as well as to build web APIs.
Aside from that, programmers use back-end languages to create interactive online tools, mobile apps, desktop apps, websites, online games, software prototypes, etc.
Below you can find a list of the top 6 most popular back-end languages:
Python is a server-side coding language used in software development. It is a high-level, all-purpose, interpreted, and object-oriented programming language developers use to build software.
Python uses range from machine learning to task automation, data analysis, building websites, and testing software. Its versatility and beginner-friendliness have made it one of the most used computer coding languages.
As a programming language, it is used to process data, store, retrieve, or update information in database management, route URL, and test software.
Software developers often use Python in web development to build the server side of a website or application. Django and Flask are two common Python frameworks used in web development.

PHP, an acronym for Hypertext Preprocessor, is an open-source, server-side scripting and programming language developers use to create the back end of a website, application or CRM.
It is versatile and great for beginners and experts, and it is updated regularly to follow the latest technology trends.
Unlike front-end languages that run on the client side, PHP runs on the server and makes it possible to communicate with the database when building the back end of your website.
When the server receives a script, it will process the request and send the result or output displayed on the browser in HTML format.
Along with SQL, you can store, retrieve or update information in your database and make a website dynamic by displaying information from the database to the browser.
Features of PHP
- Beginner-friendly. PHP is one of the few server-side languages that is easy for beginners to learn. Its learning curve is not as steep as other languages.
- Speed. It is about three times faster than most programming languages at runtime, which means that any website built with it loads faster and boosts SEO.
- General purpose. It is a general-purpose back-end language that is useful in creating e-commerce websites, blogs, desktop applications and social media apps like Facebook. Also, you can send emails with PHP.
- Support. PHP is a popular programming language with a large community that can assist you if there is an error in your code. Also, it has many documentation and information online that can provide guidance.

- Real-time chats. It is well-suited for processing real-time communication due to its single-thread asynchronous nature, making it valuable in building chatbots, multi-person chat and push notifications.
- Data streaming. Entertainment companies like Netflix use NodeJS for streaming data because it is lightweight and fast.
- Single Page Applications (SPAs). NodeJs event loop makes it possible to build Single Page Applications where the whole application is loaded on a single page.
C# or C-Sharp
C# is a general-purpose, object-oriented programming language developed by Microsoft. It is an increment of C++ primarily used on the Windows .NET framework and remains the primary technology for developing desktop applications on Windows.
As a modern all-purpose coding language, C# developers can use it to perform various tasks that span various professions.
Uses of C#
Software engineers can use C# to create several programs and applications like mobile and desktop apps, cloud-based services, websites, games, and enterprise software.
- Web development. Software developers use C# to build dynamic websites on the .NET platform. Since C# is object-oriented, developers can build efficient, easily scalable and maintainable websites.

- Games. Another use of C# is in the development of games. Unity Engine is an example of a game development platform that uses C# to make games. C# seamlessly integrates with Unity and can be used on any modern mobile device with a cross-platform technology like Xamarin.
C# is highly scalable and easy to maintain. The strict nature of its static code makes it reliably consistent, allowing developers to make an easy adjustments and smooth maintenance.
Aside from that, it has a vast developer community that provides support when you have problems with your code.
SQL, which stands for Structure Query Language, is a standardised programming language developers can use to manage relational databases and carry out various operations on the data.
As a coding language, it offers looping, logic directives, variables, etc. But it is not a language like Java or C++. It is considered a fourth-generation because it contains statements similar to human language, while Java or C++ are third-generation languages.
Instead of being a language for building websites or apps, it is used to store, retrieve and manipulate data in a database.
Back-end programmers can use SQL to get valuable server-side information to carry out tasks that allow a website's or app's front end to run smoothly.
Standard Query Language is used for the following:
- Modifying the database table and index structures,
- Adding, updating and deleting tables or rows in the database,
- Retrieving information from a relational database management system.
- Developers can use SQL for transaction processing, analytics applications and other apps that communicate with a relational database.
