Quick Summary
Backend development handles server-side operations, database management, APIs, and business logic that enable application functionality.
Backend Development, or server-side development, focuses on the behind-the-scenes functionality of web applications. It involves creating and maintaining the technology that powers the frontend, including databases, server logic, and APIs.
Backend Components
- Server: Handles requests and responses
- Database: Stores and retrieves data
- API: Communication interface
- Business Logic: Application rules and processes
- Authentication: User identity and security
Popular Backend Languages
| Language | Frameworks | Best For |
