Software architecture defines the overall structure and design of a system. It includes:
Components:
- Modules: Distinct functional units
- Services: Independent, reusable functions
- Databases: Data storage and management systems
Interfaces:
- APIs: Define how components interact
- User interfaces: How users interact with the system
- External interfaces: Connections to other systems
Relationships:
- Dependencies: How components rely on each other
- Data flow: How information moves through the system
- Control flow: The sequence of operations
Architecture Design Patterns:
- MVC: Model-View-Controller pattern
- Microservices: Distributed system architecture
- Layered architecture: Separation of concerns
Non-Functional Requirements:
- Scalability: Ability to handle growth
- Security: Protection against threats
- Performance: Speed and efficiency
Good architecture ensures a system is maintainable, scalable and efficient.
