Backend

The backend is the technical foundation of a web application, responsible for processing data, managing databases, and handling the application's logic and functionality behind the scenes. It serves as the bridge between the frontend (user interface) and the database, enabling users to interact with the application and facilitating the storage and retrieval of data.

Business Logic: The backend contains the application's core logic, including user authentication, data validation, calculations, and other processing tasks.

Database Interaction: It manages the storage, retrieval, and modification of data in databases, ensuring data integrity and efficiency.

APIs: The backend exposes APIs that allow the frontend to communicate with it, enabling actions like retrieving data, submitting forms, and performing various tasks.

Server: The backend is hosted on servers, which handle requests from users, process them, and send back the appropriate responses.

Security: It implements security measures to protect data and ensure authorized access, often involving encryption, authentication, and authorization mechanisms.

Scalability: The backend architecture is designed to accommodate different levels of user traffic and can be scaled up or down as needed.
