Syllabus Point
- Assess the contribution of back-end web development to the success of a web application
Understanding the critical role of backend development in handling business logic, managing data, and ensuring security is essential for recognising how backend and frontend work together to create successful web applications.
Key functions of backend development
- Handles user authentication
- Processes business logic
- Manages databases
- Provides APIs for front end communication
- Scalability
- Performance optimisation (async)
Package manager
Used to install and manage packages used in the backend.
Separation from the front end
Modern web applications often separate the front and back end using microservices and RESTful APIs.
Advantages
- Handles core logic, data processing, integration with databases
- Enables secure communication, data protection, access control
- Supports scalability and performance
- Allows integration with APIs, external services and gateways
- Dynamic content generation
Disadvantages
- More complex than front end
- Can increase development time and maintenance effort
- Server configuration and deployment challenging for beginners
- Poorly designed backend can bottleneck performance and UX
