What Is Backend Development?
Before diving into the Backend Development Roadmap: A Complete Guide, let’s understand what backend development actually means.
Think about ordering food online.
You open an app, browse restaurants, place an order, and make a payment.
What happens behind the scenes?
A lot.
The backend handles:
- User authentication
- Database storage
- Payment processing
- Business logic
- Order management
- Notifications
In simple terms, the backend is the engine that powers a website or application.
The frontend is what users see.
The backend is what makes everything work.
