What are the three components of system design?
The three primary components of system design are:
1. Frontend (Client-Side)
The frontend is the part of the system that users interact with directly, usually through web or mobile interfaces. It involves:
- User interface (UI) design
- User experience (UX) optimization
- Handling user input and interacting with the backend via APIs
2. Backend (Server-Side)
The backend consists of the server-side components that process requests, handle business logic, and interact with the database. Key elements include:
- Application servers: Execute the core business logic.
- APIs: Facilitate communication between the frontend and backend.
- Databases: Store and retrieve data efficiently.
3. Data Storage
Data storage encompasses the databases and file storage systems that store the application's data. This includes:
- Relational Databases (SQL): For structured data.
- NoSQL Databases: For unstructured or flexible data types.
- Caching systems: Tools like Redis or Memcached for improving data retrieval speed.
These three components work together to deliver a complete system that handles both user interactions and data processing.
