Backendjärjestelmä

Backendjärjestelmä, often referred to as the server-side of an application, is the part that users don't directly interact with. It encompasses the server, application logic, and databases that power a website or software. This system is responsible for handling data storage, processing, and retrieval, as well as managing user authentication and authorization. When a user makes a request through the frontend interface, the backend system receives that request, processes it, and sends back the necessary information or performs the requested action. Key components of a backendjärjestelmä include programming languages like Python, Java, or Node.js, databases such as PostgreSQL or MongoDB, and web servers like Apache or Nginx. The backend's primary role is to ensure the application functions correctly, securely, and efficiently, providing the underlying infrastructure for the user-facing frontend.
