ETL stands for extraction, transformation, loading, and it refers to the composite process of transferring data from one application or automated information system to another. The purpose of any ETL application is to deliver data from external systems to the user’s system in a timely manner. As a rule, ETL applications are used when transferring data from external sources into the database of business intelligence systems. Therefore, organization of the ETL process is an integral part of the development project of almost any database. Our experts deploy custom or ready-made ETL and BI tools on-premise through SaaS or hybrid models.

      Frequently Asked Questions (FAQ)

      Backend is the part of a website that is not visible from the outside because it is an executable program code, and users see the interface drawn by the browser (frontend), that is, the layout of sites in HTML.
      The back end software engineer works with the tools available on the server where the site is located. They can use any universal programming language, for example, back end Python, PHP, Java, or Ruby. The choice may be affected by the specific task and the project.
      The components of the backend web development also include server-side databases and database management systems: MySQL, SQLite, PostgreSQL, and MongoDB. Depending on the tools used, developer responsibilities vary.

      Server-side is necessary for safely keeping and allocating data, app hosting, and enhanced security. Backend developers prescribe the logic of IT products. They are responsible for the internal content of the system, data storage, and transfer. They also test the API (application programming interface) – a special set of commands/controls. It is designed for interaction of different programs with each other.
      In other words, the back end developer makes sure that the server generates a response and sends it to the right computer. Many people don’t even think about backend actions; for them, the page loads by itself.

      Those are services that offer backend web development or developers. Such experts are responsible for the functional core of the software, site, or mobile application. IntelliSoft is one of the companies that can implement your ideas by offering qualified engineers.

      They typically include three parts:

      • The server. It is basically a machine that processes client’s requests and returns the necessary information. At the same time, one server can process requests from many clients, just as one client can access many servers.
      • API. The application programming interface is the part of the server with which the client directly interacts. The idea is to let users easily find a website and make it through to it.
      • The database. The server only processes information, but does not store it. For this purpose, there are special tools called databases. For example, when you make a purchase in an online store, the server accesses the database to check the availability of goods, and only then allows you to buy them.

      The backend is the heart of the website, the logic of its operation, and the interaction between the server and the content. Without this software-hardware complex, the website and the server will not work correctly.

      Top four back end programming languages as of today are:

      • Python
      • PHP
      • Java
      • C#

      Say, a user goes to the Amazon website to look for a dress. A backend dev applies server-side language to retrieve all info about available dresses from a database. That data is processed in an app and returned to the user through the frontend language.
