Back-End
Backend development is a set of hardware and software with which the logic of the site is
implemented. It is one of the most important parts, this is where machine logic makes all
beautiful things created by designers and implemented by frontend developers work. Simply put,
this is something that is hidden from the user's eyes and occurs outside of his browser and
computer.
For example, when you enter a query on the search engine page and press the Enter key, the
frontend ends and the backend begins. Your request is sent to the Google or Yandex server, where
the search algorithms are located. This is where all the “magic” happens. As soon as the
information that you were looking for appears on the monitor, it again returns to the frontend
zone.
We use different backend languages considering clients' demands, for example:
Node JS, C#,
Java, PHP, Ruby, C++, GoLang.
Also, different database management systems are used for backend development:
MySQL,
PostgreSQL,
SQLite, MongoDB.
