What is backend development

Back-end development means that developers write code that cannot be directly seen. Development runs in the background and controls front-end content, including programming architecture, database management and processing-related business logic.

For a website, users can only see part of the website. In most cases, most of the website is invisible. These invisible things are called backends. Next, in the article, I will introduce you to the knowledge about the backends in detail. I hope it will be helpful to you.

Backend introduction

The backend refers to the content that runs in the background and controls the frontend. It is mainly responsible for programming architecture ideas, managing databases, etc. The backend is more about applying to the database and interacting to process the corresponding business logic. What it needs to consider is how to implement functions, data access, platform stability and performance, etc. It involves dynamic languages ​​such as PHP, ASP, JSP, etc.

What exactly is back-end development?

In reality, even though front-end development gets most of the glory, most of the code that exists in the world (arguably the most useful code) is the backend that end users never see. terminal code.

Simply put, back-end development is code written by developers that cannot be directly seen.

What does a backend developer do?

What a backend developer does varies greatly depending on the size and scope of the application they are working on. When I was a backend developer, I did a lot of work on business logic in applications, as well as extracting and retrieving data from the frontend.

In the web development world, most backend developers are engaged in building the actual logic behind the applications they are working on.

Typically, front-end developers build the user interface, while back-end developers write the code to make it work. For example, a front-end developer creates an interface in an application with a button that, when pressed, gets the customer's data.

The backend developer writes the code that makes the button work by indicating what data to pull from the database and pass it back to the frontend (and ultimately display there).

Back-end developers may also be heavily involved in system architecture, deciding how to organize the system's logic so that it can be maintained and operated properly.

He may be involved in building a framework or system architecture to make it easier to program. Backend developers spend more time implementing algorithms and solving problems than frontend developers.

I have always liked back-end development work because it is more of a challenge.

This is not to say that front-end developers don't solve hard problems, but often front-end development jobs are more about creating the user interface and the content associated with it than implementing the actual business logic that makes the application work.

Main technologies and skills of back-end development

As a front-end developer you need to know a series of tools for creating user interfaces, and back-end development People often use a completely different set of tools and skills to do their jobs efficiently. Backend developers are most exposed to knowledge related to SQL databases. Because most back-end data needs to be connected to the database.

The work that the backend often needs to do is to write, read and process data from the database or other data sources. You also need to understand PHP web framework, ASP.net MVC, etc. or server-side web development frameworks used to build applications

Summary: As a qualified back-end developer, you should master various frameworks and libraries, and integrate them into applications and build code and business logic.
