Back-End Development – What Is It?


Guys, today our topic is back-end development. Have you ever been interested in what way are all the sites you are getting in everyday running? What lays behind the user-friendly interface and makes sites work without permanent failures and errors? If you said ‘Yes’ at least once, this article is for you.

The fact is that there is a piece of app a user sees, but, usually, the main part of this app remains unseen. And this is what we are talking about – mystical “back-end.”

In the greater part of various applications, there is much more non-user interface code than user-interface code. All the core, logical operations which run an app or a site, as a rule, happens behind the scenes.

And this is a back-end developer who works under the hidden part of frontispiecemain application logic.

What Does “Back-End Development” Mean?

Well, in a word, back-end development is writing a code that is not seen and cannot be experienced directly by a user.

This could involve not only back-end web development, but core application logic, databases, data and application integration, API and other back end processes as well.

In fact, the major part of the existing code – or at least the most useful of it – de facto is back-end code and it is always imperceptible for the end user.

What Do Back-End Developers Do?

The website back-end consists of three main parts that a user never sees: a server, an application, and a database. This code adds utility to everything the front-end developer creates. In general, the majority of back-end developers consider themselves as developers who are building the actual logic behind the application they are working on.

But, surely, back-end developer’s tasks can differ a lot, depending on the size of the app he’s working on.

A back-end developer often works with system’s architecture and builds frameworks to make it easier to program against.

Technologies and Skills To Use in Back-End Development

Back-end developers, as a rule, should have a set of tools and skills to do their jobs effectively.

One of the most essential skills for back-end developers is SQL and databases knowledge.

Database expertise is a must-have skill for a back-end developer as . The most common databases are Oracle, Microsoft SQL Server, MySQL.

Why is it so important? – because back-end developer has to write, read, and process data from a database or other data source.

Back-end developers needs to be familiar with server-side languages for the technology stack they are using.

Java and C# are the most frequently used languages for back-end development. Back-end developer has also to be in the knowledge of PHP web frameworks, Ruby on Rails, or any other server-side framework which is used for building the application.

And, surely, a good back-end developer needs to know about design patterns, algorithms, data structures, etc., as the back-end is usually responsible for the business logic.
