What is the Layered Architecture Pattern?
The layered architecture pattern is a software design approach that organizes code into distinct layers, each with specific responsibilities. This separation of concerns enhances the maintainability, scalability, and testability of software systems.
Key Layers
- Presentation Layer: Responsible for user interface and user interaction.
- Business Logic Layer: Contains the core functionality and business rules of the application.
- Data Access Layer: Manages data storage and retrieval operations.
- Common Services Layer: Provides reusable services such as logging and authentication.
Benefits
- Separation of concerns enhances code clarity.
- Easier to modify one layer without impacting others.
- Facilitates team collaboration by allowing developers to work on different layers concurrently.
Conclusion
The layered architecture pattern is instrumental in building robust software applications by promoting organized code structure and clear responsibilities across different components. It is widely used in enterprise applications and can be adopted in various programming languages.
