What is the role of the application programming interface (API) in the interaction between the database and the user interface?

API (Application Programming Interface) acts as an intermediary between the database and the user interface. It provides a standardized way to request, retrieve, and modify data, hiding the details of database implementation.

Role of API:

• Abstracts the complexity of working with the database.
• Ensures security by controlling access to data.
• Allows changing the internal structure of the database without affecting the UI.
• Handles business logic and data validation.

For example, the user interface sends a request through the API, the API performs operations with the database, and returns the result for display to the user.
