Website backend design

What Is Back-end?

The back-end is all of the technology required to process the incoming request and generate and send the response to the client. This typically includes three major parts:

• The server. This is the computer that receives requests.
• The app. This is the application running on the server that listens for requests, retrieves information from the database, and sends a response.
• The database. Databases are used to organize and persist data.

What Is Backend Development?

So far, what you have is an example of a static website — its content doesn’t really change much. For static sites, all the necessary information that determines what’s on the web page is in the frontend code itself. Static websites are good for showcasing things like businesses, restaurants, portfolios, or professional profiles. But if you want to turn your site into something that users can interact with, you’ll need to get more in-depth with regard to what’s going on behind the scenes of the website.

The backend (or “server-side”) is the portion of the website you don’t see. It’s responsible for storing and organizing data, and ensuring everything on the client-side actually works. The backend communicates with the front-end, sending and receiving information to be displayed as a web page. Whenever you fill out a contact form, type in a web address, or make a purchase (any user interaction on the client-side), your browser sends a request to the server-side, which returns information in the form of frontend code that the browser can interpret and display.

Your new site will need to have additional backend components to make it a dynamic web application — a website whose content can change based on what is in its database , and that can be modified by user input. This is distinct from a static website, which doesn’t require a database because its content generally stays the same.

Skill sets required to become a Backend Developer

A backend developer works with the following

• Web Development Languages
• Database and cache
• Server
• API (REST & SOAP)

WHAT IS A DATABASE, AND WHY DO WE NEED TO USE THEM?

Databases are commonly used on the back-end of web applications. These databases provide an interface to save data in a persistent way to memory. Storing the data in a database both reduces the load on the main memory of the server CPU and allows the data to be retrieved if the server crashes or loses power.

Roles and responsibilities of Backend Developer

• The backend developer job is to understand the goals of the website and come up with effective solutions
• Storing data and also ensuring that it is displayed to that user who are supposed to have access to it
• Responsible for developing Payment processing system like accepting data, securely storing that info, and making charges to that payment
• Manage APIs resources which work across devices
• He or she might be involved in the architecture of a system and Data science analyses.
• Developers are responsible to organize the logic of the system which runs across various devices
• Backend developer also needs to involved in building frameworks or the architecture to make it easier to program against.
• Back-end developers should have the skill for implementing algorithms and solving system related problems.
