The frontend is everything the user sees and interacts with in a web application – like buttons, text, forms, images, navigation menus.
The backend powers the application: processes requests, manages data, and sends responses.These are used to build the server-side logic.
A database is where the application stores, organizes, and retrieves data.Data is stored in tables (rows & columns).Structured and uses SQL (Structured Query Language).
