What is Backend Development?

Backend development is also known as server-sider-development. It is everything that the users don’t see and contains behind the scenes activities that occur performing any action on a website or a app. It focuses primarily on databases, backend logic, APIs and Servers. This is called backend development in a simple way. The backend of a website or a mobile app is a combination of servers, applications, and databases, it reads the data from a database and update the data and delete the data or information from the database. Recall the example of a Medium website, What do you think happen when you submit your login/Signup details? To give a brief overview let us see the terminology of it.

When you click on submit button after filling the form, they are sent to the server that then processes your data and stores it in the database. Now they’d have the details shared by the user, then it stores that same data in a database. But did you see any of this happening? No, because it happened behind the scenes. Thus, it is known as the backend development. It is just an overview of what the backend is, but this is not it, there is a lot to it.

Now we’d have an idea what backend is? let us discuss what backend developers are?

A backend developer is one who makes us of the technology required to develop the products for the backend of any website or a app. A backend developer is responsible for building a structure of a software application.

Backend developers typically work in groups with a team. They’d use various types of tools, languages, and frameworks to accomplish these tasks. To do all this, they use a variety of server-side languages, including Java, .NET, PHP, Ruby, NodeJS, and etc. They do use databases like MySQL, MongoDB, Oracle, SQL, PostgreSQL, HarperDB, etc. to create, read, update, and delete the data and server it back to the client-side or the frontend of the application/website.

Backend Developer Skills

To become a backend developer, you should have good knowledge about these topics:

  • Backend Programming Languages

Backend Programming Language

There are 2- Kinds of backend programming language:

  • Object-Oriented (OOP) — It is a programming architecture built upon the concept of classes and objects. It is used to structure a program into simple, reusable pieces of code snippets (called classes), which are then used to create individual instances of objects. A class is an abstract blueprint that is used to create more concrete and specific objects. And objects are the instances of a class.
  1. In object-oriented programming languages, statements are executed in a particular order. Some of the popular object-oriented backend languages include Python, Java, and .NET.
  • Functional — Functional programming is a programming paradigm in which everything is bound in mathematical functions style. It is a way of software development by creating pure functions. Functional programming languages avoid the concepts of shared state and mutable data that is observed in OOP. They emphasize expressions and declarations rather than execution.

Some of the companies that use PHP as a backend are Facebook, Lyft, Viber, and Hootsuite.

  • Python — Python was first curated by Guido van Rossum in 1991. Python is an interpreted general-purpose programming language. It declines the need for coding to a significant level.

Every website needs a database to deal with the client data. A database stores the data and site content in a way that makes it simple to recover, arrange, alter, and store information. A backend developer should have extensive knowledge of various DBMS technologies.

There are two types of databases available in the market — SQL, and NoSQL. A SQL database is one where the data is mapped in a table and each one is linked to another in a significant way. SQL databases work on queries and produce results based on them. The NoSQL database where, unlike SQL, there is no need to structure the data beforehand. NoSQL databases work essentially on JSON (JavaScript Object Notation) and XML (Extensible Markup Language).

Knowledge of APIs

The entire internet works via the medium of APIs. API stands for Application Programming Interface and API is a medium through which two computer software can talk to each other.

API is a set of rules and definitions that allow different clients, software, or services to communicate with each other over the internet. When two systems communicate, the server is the one that provides the API, and the client is the one who consumes it.

APIs take a request from the client or user and send it to the server, which then sends back a response based on the request.

This communication is done through HTTP methods such as:

  • GET: used to retrieve a resource.

Backend developers should have extensive knowledge about APIs since they are medium which enables data transfer. APIs generally act as a mediator between the backend and the databases enabling the developers to fetch the user data. Backend developers create APIs using various languages and frameworks including Python, NodeJS, etc. These APIs then can be consumed by frontend developers to collect the data, and show it on the frontend side of the website, and enhance the User Experience.

The two most recognized positions for API information are JSON, which represents JavaScript Object Notation, and XML, which represents eXtensible Markup Language.

Knwoledge of Servers

Every web application that you see today runs on a remote PC called a server. On the internet, the term “server” is commonly used to refer to the computer system that receives requests for web-based files which includes HTML, CSS, Javascript, etc., and sends those files to the client.

Since servers are the most commonly used medium to deliver important services, most servers are never turned off. This part of the servers makes it an essential element for a backend developer to learn about. Some examples of the servers are Apache, Nginx, IIS servers, and Microsoft IIS.

Some other backend development skills include –

  • Ability to manage a hosting environment along with database administration.

Conclusion

The web is a rapidly evolving universe. Everything that we use and see in our daily lives has moved to the web. With this upsurge in technology, the demand for backend developers is also rising.
